Executive Summary This Capability Statement presents the Oman Electricity Transmission Company’s development plans for the 400kV, 220kV and 132kV transmission systems for the years 2012 to 2016. The Statement includes data for the generators, loads, overhead lines, cables, transformers and capacitor banks used in the development of transmission system models for the power system studies undertaken with OETC’s DIgSILENT power system analysis software, version 14, in preparation of this Capability Statement. The Statement also includes the results of power system analysis of the transmission system that defines system performance when operating under the extremes of peak and minimum demand in each of the five years. From this analysis an assessment has been made of the opportunities for the connection of new generation and new demand on the system. Table 1 lists the schedule for committed and planned system development projects on the 400 kV, 220 kV and 132 kV transmission systems, although it should be noted that not all of the projects listed have full authorisation at this time. Implementation of these system development projects will increase the number of 220/132 kV grid stations from eight to fourteen before the summer peak of 2016, with an additional installed firm grid substation capacity of 6,000 MVA. The number of 132/33 kV grid stations will also increase from the forty-six in service at the beginning of 2012 to sixtey five by the summer peak of 2016. In 2010 the company has introduced direct voltage transformation from 132 kV to 11 kV on the transmission system with respective 132/11 kV substation for the major residential/tourism developments at Azaiba Coast (Wave Project) in Muscat area. In addition, during 2012 the company introduced direct voltage transformation from 220kV to 33kV on the transmission system with respective of 220/33 kV substation for the major residential/tourism developments at Blue City in Batinah South area. It is also one of OETC’s strategic planning concepts to complete a 220kV double circuit ring around northern Oman. In 2010 the 220kV connection between the Sohar Interconnector Station (SIS) and Mahadah (Al-Wasit) was completed to help in linking the main load centre in Oman (Muscat) with the UAE (Abu Dhabi Transco) and the rest of the GCC Grid via Sohar and the rapidly developing Sohar port and industrial area. By the year 2012 the 220kV transmission systems will also be extended from Misfah in the Muscat area to Jahloot and further eastwards to Sur. In addition, OETC plans to complete building a 220 kV line between Mahadah to Ibri before summer 2012 to support the voltage and meet the expected load growth in the area. Morever, OETC will introduce the first 400kV system which includes 400kVconnection between Jahloot grid station and Sur power station, 400kV connection between Sur power station and Izki grid station and 400kV connection between Izki grid station and Misfah grid station. Four 400/220kV grid stations will be installed at Sur, Jahloot, Izki and Misfah areas. In accordance with Condition 27 of OETC’s Transmission Licence, the power flow studies presented in this Capability Statement are based on demand forecast data provided by the Oman Power and Water Procurement Company (OPWP) as per its recent Seven-Year Statement. The forecast has been disaggregated by grid station, according to available Distribution companies (DISCO) data, for detailed power system analysis. To be able to perform the studies and produce the results presented in this statement, the Strategic Planning and Studies team has set a deadline to receive data from various parties (OPWP, DISCO, OETC internal departments) as per the Grid Code requirements. Any information received after the deadline will be included in the next Five- Year Annul Transmission Capability Statement (2013-2017). Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 8 In order to model future system development as accurately as possible the distribution companies are required by the Grid Code to provide OETC with information that identifies their load transfer plans, including the load to be transferred, the timing and the grid stations involved, data that is also provided to OPWP for its own forecast of generation requirements. From the individual demand forecasts of the distribution companies, OETC has developed its own demand forecast inline with most of distribution companies provided system forecast for the transmission system as a whole, including the load transfers between grid stations that are then incorporated into the power system models for each year. The forecast average annual growth in system demand of about 10.22 % over the period 2012 –2016 drives many of the planned grid station reinforcements with a large portion of the additional demand supplied to the distribution companies through the 132/33 kV grid stations. To meet security of supply requirements and provide load relief to the heavier loaded grid stations it will be necessary to transfer excess load to the new or existing grid stations. Comparison of the demand forecast with generation availability as defined in the latest OPWP Seven- Year Statement shows sufficient availability in generation capacity after introducing the new generating capacity from Barka Phase-3 (750MW), Sohar Phase-2 (750MW) and Sur IPP (2000MW). As the demand grows, there is a greater need to extend the 220kV transmission systems so that bulk power is transmitted at this voltage rather than 132kV in order to avoid overloads, improve voltages and reduce power losses. Consequently, it is OETC’s objective to operate 220kV as the main transmission voltage and use 132kV for sub-transmission. From Table 1 a total of 54 transmission projects are planned over a five year period, most of projects are designed to increase the transmission system capacity so that it can meet future growth in demand and satisfy the security criteria. This is a major programme of capital investment in its infrastructure that will be spread across the whole network to improve transmission system performance across northern Oman. Power system studies presented in this Statement confirm that the planned investment in 400/220 kV, 220/132 kV and 132/33 kV grid stations and transmission circuits will provide substantial spare capacity on the transmission systems to well beyond 2016. The major technical issue identified in the studies was with high short-circuit fault levels on the 132 kV bus bars at 4 grid stations in the Muscat area. The grid stations at Ghubrah, Bousher, Rusail and Madinat Sultan Qaboos (MSQ) were all shown in earlier studies (OETC Five Year Capability Statement 2008-2012) to have high 132 kV fault levels. Accordingly, OETC has taken appropriate remedial action to address this problem by implementing in the short–term, measures to split the 132 kV bus bars at Rusail and Ghubrah. In 2011, the 132 kV bus bars were split at Rusail and Ghubrah power stations to reduce the short circuit current with zero cost. This will be continued in 2012. In 2013 Rusail will no longer need splitting due to the network development and reconfiguration works which will take place to facilitate the addition of new IPPs, and therefore the Rusail bus bars will be returned to normal operation. In 2014, many generating units at Ghubrah power plant will be retired and no more splitting will be needed. Load flow studies have confirmed that the voltage levels across the transmission system can be maintained within the ±10 % limits as defined in the Grid Code. At Al Hail and at other remote locations, such as Sur at the eastern end of the transmission system, there is a strong case for the deployment of reactive compensation as a cost effective means of improving the system Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 9 voltage. Similarly, with the demand in the Muscat area continuing to grow there are occasions when some grid stations in the Muscat area suffer reduced voltages at times of heavy load. To overcome this problem, Muscat Electricity Distribution Company (MEDC) has installed new capacitor banks on the 33 kV bus bars at Bousher, MSQ, Mawalleh, Mabellah, Qurum, and Jahloot grid stations in 2010 and these capacitor banks produced a significant improvement in the voltage profile across the Muscat area. Also, Majan and Mazoon Distribution Companies have installed capacitor banks at some places in their network. With these capacitor banks the voltage profile has been significantely improved. The voltage problems experienced in the Al Dhahirah area has led OETC to review its plans for system reinforcement to this area with the 220 kV system extended from Mahadah (Al Wasit) to Ibri, with Ibri scheduled upgraded before the 2012 peak. When this work is completed, the transmission system in this area will be fully compliant with the voltage requirements set by the Grid Code and the Transmission Security Standard requirements set by Licence Condition 26. The Statement has reviewed the opportunities for the connection of new generation and new demand and identified those grid stations with substantial spare capacity where it should be possible to connect new demand to the system. Section 2 of the Statement provides an introduction to the document, identifying the main related documentation and the key changes that have taken place on the transmission system since the previous issue of the Statement. Section 3 identifies the technical requirements of the Grid Code and the Transmission Licence with specific attention to system voltage, frequency and security of supply. Section 4 describes the main engineering standards used by OETC in its planning and design of the transmission system. Section 5 describes the existing transmission system and summarises the planned developments in each year over the period 2012 to 2016. Section 6 identifies the existing and planned developments in generation and describes the interconnections both inside Oman and internationally, i.e. PDO and the UAE (Abu Dhabi Transco) respectively. Section 7 presents the demand forecast and compares this with the generation capacity available. Section 8 discusses transmission system performance and presents the results of load flow and short-circuits studies that show the performance of the transmission system at both maximum and minimum peak demand in each year from 2012 to 2016. Section 9 identifies the development opportunities for the connection of new demand and new generating plant to the transmission system. Section 10 presents the areas of the network where network components will be operating above firm capacity during the period 2012 - 2016 and identifies the need for new or renewed derogations from application of the Transmission Security Standard.

Introduction 2.1 Licence conditions, Codes and Standards This Transmission System Five-Year Capability Statement covers the period 2012 – 2016 which has been prepared by the Oman Electricity Transmission Company S.A.O.C. (OETC) in accordance with the requirements set down under Licence Condition 27 of the Electricity Transmission and Dispatch Licence granted to the Company on 1 May 2005 by the Authority of Electricity Regulation (AER). The Licence has been granted under the powers invested in the Authority by Article (2) of the Law for the Regulation and Privatisation of the Electricity and Related Water Sector promulgated by Royal Decree 78/2004. The purpose of the Statement is to provide up-to-date transmission system data for potential and existing users of the transmission system so they can identify those parts of the transmission system which offer the opportunity for future development. The Statement is required to be updated annually so that users and potential users of the transmission system are furnished with the latest information. Potential users of the transmission system should be aware of the following main documents that influence the planning and future development of the transmission system infrastructure: i) The Grid Code for the Sultanate of Oman. ii) The Electricity Transmission and Dispatch Licence granted to OETC, notably Licence Condition 26, which defines the requirements for the Security Standards and the maintaining of an Efficient and Economic Transmission System. iii) The approved Transmission Security Standards prepared in accordance with Condition 26 of OETC’s Transmission and Dispatch Licence. iv) The Statement of Charges for Connection to the OETC Electricity Transmission System. v) The Statement of Charges for the Use of the OETC Electricity Transmission System. 2.2 System Development since the 2011-2015 Statement Since the issue of the previous Capability Statement, covering the period 2011 – 2015, the following projects have been or will be completed and energized in time to meet 2012 system peak demand: 1. Installation of fourth 125 MVA transformer at 132/33 kV Bousher Grid Station. 2. Construction of the 132/33kV grid station at Yitti and the associated 132 kV transmission system. 3. Construction of the 132/33kV grid station at Qurum and the associated 132 kV transmission system. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 25 4. Construction of the 132/33kV grid station at Muttrah and the associated 132 kV transmission system. 5. Replacing of the wooden pole O/H lines with steel tower between Mahadah (Al Wasit) and Bureimi grid stations. 6. Construction of the 220/33kV grid station at Blue City. 7. Installation of third 125 MVA transformer at 132/33 kV Barka Main Grid Station. 8. Upgrade Seeb Main 132/33kV grid station from 2 x 63 MVA to 2 x 125 MVA transformers. 9. Upgrade of Dhahirah system from 132kV to 220kV. 10. Construction of 220kV grid station at Sohar for the new Sohar-2 IPP. 11. Construction of the132/33kV grid station at Quriyat and the associated 132 kV transmission system. 12. Reconnection of 132kV lines within Muscat Area. 13. Construction of Misfah 220kV and Barka grid stations and installation of required O/H lines. 2.3 Improvements in the preparation of the Statement Since the issue of the Transmission System Capability Statement for 2011 – 2015 there have been a number of improvements in the data and the power system modelling upon which the studies that are discussed in the Statement are based. The most significant of these are: i. The Statement presents solutions of all problems reported in the Five Year Capability Statement (2008-2012). By the end of the period covered by the present Statement, problems of line and transformer loadings, voltage, and fault current issues will be completely removed. ii. The OETC demand forecast is based on the data provided by the OPWP and distribution companies. iii. Updating the rating of OHL and underground cable conductors. The rating of the double circuit 132kV OHTL with 400mm2 AAAC twin-Yew conductors according to the Oman Electrical Standards OES-32 is 300MVA, while the value used in previous capability statements is 261MVA and the rating of the double circuit 220kV OHTL twin-Araucaria conductors is 673MVA, while the value used in previous capability statements is 762MVA. These changes because of the updated calculation for the overhead lines currents taken into consideration Oman climate condition such as; Wind speed (), Solar irradiance ( ), Ambient temperature ( ), Emissivity factor () and Solar absorption Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 26 coefficient (). The updated values of the line rating in this statement represent the worst weather condition with low wind speed and emissivity factor and with high solar irradiance, ambient temperature and solar absorption coefficient. These values will be used for the planning propose and in the real operation the weather condition is better and the lines can take more power when the wind speed is high and ambient temperature is low (the updated values will not have any implications on connected costumers or power plants). iv. Detailed representation of Sohar Aluminum power plant in the Model. v. Updating Barka-3, Sohar-2 and Sur power plants’ data. vi. Updating the operational limits of generating units according to the received information from the OPWP. The improvements in the demand forecast and the power system modelling should result in similar improvements being achieved in the accuracy of the power system studies upon which network development planning is based. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 27 3. Technical requirements for compliance with the Grid Code and Licence In order to comply with Condition 26 of the Electricity Transmission and Dispatch Licence the transmission system must be planned, designed and operated to provide a secure, efficient and economic supply of electricity that is of an acceptable quality to its users. Whilst Condition 26 specifically sets out the Security of Supply requirements, the most important characteristics that determine the quality of supply are frequency and voltage. The requirements for maintaining transmission system frequency and voltage within specified operating limits are set out in the Grid Code, and most clearly defined under conditions CC.6.1.1 and CC.6.1.2 respectively of the Connection Conditions Code. Other issues that relate to the planning of an economic and cost effective transmission system that provides a voltage supply of acceptable quality, such as standardisation of equipment ratings, limitation of system losses, and the control and limitation of disturbing factors that affect the voltage waveform are covered by relevant Omani and/or International Standards. 3.1 System Frequency In accordance with condition CC.6.1.1 of the Connection Conditions Code, OETC is required to maintain System Frequency within the following limits: a) During normal operating conditions, the nominal system frequency of the transmission system shall be 50.00Hz and will be controlled normally between 49.95Hz and 50.05Hz. b) During exceptional steady state conditions, frequency deviations will not exceed 49.90Hz to 50.10Hz unless disturbed circumstances prevail. c) Under disturbed conditions, system frequency could rise transiently to 51.50 Hz or fall to 48.0 Hz, but not exceed these limits. As CC.6.1.1 points out, the frequency of the total system is responsive to changes in the balance between the active power demand and total available generation capacity. OETC must therefore ensure that sufficient generation capacity and demand is available and connected to the system at all times to respond automatically to active power imbalances and correct any frequency change. 3.2 System Voltage In accordance with condition CC.6.1.2 of the Connection Conditions Code, OETC is required to control system voltage within the following limits: a) The voltage on the 220 kV and 132 kV parts of the Transmission System at each site with a user connection will remain within the limits of ±10% of the nominal voltage level. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 28 b) The voltage on the 66kV, 33 kV and 11 kV sides of transmission transformers at Connection Sites with Users will normally remain within the limits of ±6% of the nominal value unless abnormal conditions prevail. During some system disturbances, such as where short circuits occur, the voltage could collapse transiently to zero at the point of fault until the fault is cleared. Voltage regulation requires both active and reactive power flows across the transmission system to be carefully controlled. The physical characteristics of the plant on the transmission system also give rise to the generation and absorption of reactive power. Reactive power flows across the transmission system can give rise to substantial voltage differences and it is therefore necessary to maintain reactive power balances between sources of capacity and demand on a “zone” basis. Unlike frequency, which is consistent across an interconnected transmission system, voltages at different points on an interconnected system are determined by the local sources of demand and capacity, by the prevailing network configuration and by the reactive power flows across the network. The management of voltage requires control of reactive power and centrally dispatched generators, transformer tap-changers, can provide this by the connection of capacitor banks at 33 kV or below, or by means of static compensation. 3.3 Security of Supply In accordance with Condition 26 of the OETC Transmission Licence the capacity of the Transmission System to transmit electricity shall not be reduced in the event that a single electric line, cable, transformer, circuit breaker and/or associated plant is not in service, provided that during a period in which such single electric line, cable, transformer, circuit breaker and/or associated plant is not in service. The operating voltage of the Transmission System may reduce to any level specified from time to time for such purposes in the Grid Code. In effect, the transmission system should be planned and operated to meet the Transmission Security Standard requirements. The Transmission System taken over by OETC in 2005 had several components that failed to meet the Transmission Security Standard requirement, and the Licence recognised that it might take two years. However, by system peak 2013 all grid stations and overhead lines will meet most of required standards and criteria to bring the whole system into full compliance. To date some of these out of firm situations have been addressed, but equally the steep growth in demand has caused further circuits / transformers to become out of firm.

OETC System Design and Planning Standards In addition to the technical requirements of the Transmission Licence and the Grid Code, the principal electrical standards used by OETC in its planning and design of the 220 kV and 132 kV transmission systems are: 4.1 Oman Electrical Standard OES 11 The standard covers the topic “General Specifications for Electrical Materials and Equipment” and defines the worst case conditions for system design purposes by the following parameters: a) maximum ambient temperature (50˚C) b) maximum surface temperature for metal surfaces (80˚C) c) altitude (between sea level and 30 metres above sea level) d) maximum wind velocity (125km per hour) e) average annual rainfall (100mm) f) maximum relative humidity (100%) The standard also defines the design parameters for the 132 kV systems in terms of highest voltage (145 kV), design fault level (31.5 kA) and the requirement that the system be solidly earthed. Currently it does not specify corresponding figures for the 400 kV and 220 kV systems. 4.2 Oman Electrical Standard OES 25A and 25B These standards define the requirements for aluminium conductor steel reinforced and aluminium alloy conductor overhead lines and aluminium alloy stranded conductor overhead lines. 4.3 Oman Electrical Standard OES 27 Volume 1 of the standard covers the design requirements for a 132/33 kV, 2 x 125 MVA substation with 132 kV gas insulated switchgear, including the 33 kV switchgear. Volume 2 covers similar requirements for the 132/33 kV, 2 x 63 MVA substation with 132 kV outdoor SF6 switchgear. 4.4 Oman Electrical Standard OES 32 The standard covers the design requirements for 132 kV double circuit overhead transmission lines with 400mm 2 All Aluminium Alloy Twin Conductors (AAAC) on lattice steel towers that are deployed across much of the 132 kV transmission system. 4.5 Other Standards In cases where an Omani Standard is not applicable it is usual OETC practice to adopt the appropriate IEC Standard. This particularly applies to the design of the 400kV and 220 kV transmission systems. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 30 5. OETC Transmission System 5.1 Existing 220/132 kV Transmission System The Oman Electricity Transmission Company is authorized to undertake all regulated activities of electricity transmission and dispatch in northern Oman at voltages of 132 kV and above. The existing transmission system has two operating voltages, i.e. 220 kV and 132 kV. It extends across the whole of northern Oman and interconnects bulk consumers and generators of electricity located in the Governorate of Muscat and in the regions of Batinah, Dhahirah, Dakhliyah and Sharquiya. The transmission system was first established under the Ministry of Electricity and Water (MEW) in 1983 and underwent rapid expansion during the 1990s. Consequently much of it has less than 15 year service experience. After the electrical sector was unbundled, the OETC took over the operation of the transmission system on 1 May 2005. The present OETC transmission system consists of:  1344.6 circuit-km of 220 kV overhead transmission lines  3061.46 circuit-km of 132 kV overhead transmission lines  55.4 circuit-km of 220 kV underground cables  98.68 circuit-km of 132 kV underground cables  7630 MVA of 220/132 kV transformer capacity  320 MVA of 220/33 kV transformer capacity  10299 MVA of 132/33 kV transformer capacity  150 MVA of 132/11 kV transformer capacity  Five 220 kV interconnection grid stations  Two 220/132 kV grid stations  One 220/33 kV grid station  Six 220/132/33 kV grid stations  Forty 132/33 kV grid stations  One 132/11 kV grid station The transmission system is interconnected at 220 kV from Mahadah (Al Wasit) grid station with the transmission system of UAE (Abu Dhabi Transco) and through this interconnection it will form part of the GCC Grid that links the electricity supply systems of Kuwait, Saudi Arabia, Bahrain, Qatar, UAE and Oman. This should provide increased security of supply and benefits to the member countries in the form of cost savings from the sharing of reserve capacity and energy resources. The interconnector has been energised and brought into service in Q4 2011. The OETC transmission system is also interconnected with the Sohar Aluminum system at 220 kV via a double circuit cable line that runs between SPS on the OETC system and Sohar Aluminum 220kV busbar. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 31 Under normal conditions the power transfer across the interconnection is forecasted to be negligible, but in the event of an emergency on either network the interconnection can facilitate a power transfer of up to 300 MW to address the shortfall. The OETC transmission system is also interconnected with the PDO transmission network at 132 kV via a single circuit overhead line that runs between Nizwa on the OETC system and Nahda on the PDO system. Under normal conditions the power transfer across the interconnection is forecasted to be negligible, but in the event of an emergency on either network the interconnection can facilitate a power transfer of up to 60 MW to address the shortfall. The transmission system is supplied with electricity generated from ten gas-based power stations located at Ghubrah, Rusail, Wadi Jizzi, Manah, Al Kamil, Barka (ACWA), Barka SMN, Barka III, Sohar I and Sohar II. In addition the transmission system may be supplied from direct customers, such as Sohar Aluminium, PDO, Sohar Refinery, OMCO and OMIFCO. Three Distribution Licence holders, i.e. Muscat Electricity Distribution Company (MEDC), Mazoon Electricity Company (MZEC) and Majan Electricity Company (MJEC), take the bulk of the power transmitted through the main grid, from the 220/132/33 kV, 220/33kV, 132/33 kV and 132/11 kV grid stations. In addition to the three distribution companies, ten large private customers are directly connected to the transmission system. Six of these are connected to the transmission system in the Sohar Industrial Area. The existing private customers are:  220 kV Connections i. Sohar Aluminium Smelter ii. Shadeed Steel  132 kV Connections i. Sohar Industrial Estate ii. Sharq Steel iii. PDO iv. OMCO v. Aromatics vi. Sohar Refinery vii. OMIFCO Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 32 viii. VALE The following new customers will be directly connected during the period covered by the Statement:  Sun Matel (Zoom load) will be connected with the 220 kV Sur IPP grid station in 2015.  The New Muscat International Airport (Ministry of Transport) will be connected to Airport Heights grid station in 2012.  Muscat Steel will be connected with 132kV Rusail grid station in 2013.  Modern Steel will be connected with 132kV Rusail grid station in 2015. In 2011, the system gross peak demand was 4000MW which occurred at 15:00 hours on 18 June, an increase of 10.68 % on the 2010 peak demand. During 2011, the Electric Energy Delivered (EED) to the MIS system from connected generating plants was 18,924,219 GWh whilst that exported from the MIS to the distribution companies was 18,507.886 GWh resulting in transmission system energy losses of 416.333 GWh, which equates to a transmission system energy loss of 2.25 %. 5.2 Future System Development Projects The power system studies presented later in this Capability Statement and used to define the constraints and opportunities that exist on the transmission system over the next five years have been performed on the basis that the committed and planned development projects detailed in Appendix A and summarised below will proceed as planned and be completed to the current schedule. 5.2.1 Projects completed to meet the 2012 peak demand A geo-schematic diagram of the existing transmission system in 2012 is shown in Figure 1. In section 2.2 of this Statement it was noted that a number of projects had been completed since the 2011– 2015 Capability Statement was published and that the new works were being energised so that they were available to meet the peak demand in summer 2012. These projects will provide load relief to some of the heavily loaded grid stations and transmission circuits in addition to improving the voltage profile. The projects designed to meet the 2012 system demand include a new 132kV grid station at Muttrah, Qurum Yitti and Quriyat. And new 220kV grid station at Blue City, Sohar-II IPP, Misfah and Barka-III IPP. The upgrade of the 132 kV double circuit line between Mahadah (Al Wasit) and Bureimi. Also, the replacement of overhead lines with underground cables in Muscat area. A number of grid stations cannot maintain the Transmission Security Standard requirement and additional 125 MVA third transformer capacity is being provided at Barka Main, a fourth transformer of 125MVA capacity is added at Bousher, and the upgrading of Seeb Main transformers from 2 x 63 MVA to 2 x 125MVA to meet the demand in 2012. Other major projects scheduled for that period are the 220 kV systems which will be extended into the Al Dhahirah area. These include construction of a new 220 kV double circuits overhead transmission line from Mahadah (Al Wasit) to Ibri, where a new 220/132 kV, 2 x 500 MVA Ibri grid station will be Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 33 established. This project will help in transferring the flow of the bulk electric power to the more efficient 220 kV system, thus improving the voltage profiles in this area, and reducing power losses. Also, construction of new 132 kV line between Ibri and Dank and upgrading Ibri transformers to 125 MVA. The main investment to meet the 2012 peak is in the extension of the 220 kV transmission systems from Barka-III IPP to Misfah grid station. The new IPPs at Barka and Sohar will be connected to the 220 kV transmission system through new 220 kV GIS substations at Barka-III and Sohar-II. Sohar-II will be connected to SIS (Sohar Interconnector Station) at 220 kV via a double circuit connection. However, part of the route near the power station will have to be run underground because of difficulties in obtaining a right of way for another overhead line. 5.2.2 Projects expected to be completed to meet the 2013 peak demand Figure 2 shows in geo-schematic form the system development plan to meet the demand in 2013 peak demand. The new projects scheduled for completion in time to meet the summer peak demand in 2013 are at various stages of development and the major projects for which a consultant has been appointed for construction. The projects designed to meet the 2013 system demand include a new 132/33kV grid station at Ghubrah, Ayjah, Sur, Hamriyah (Wadi Adai-2) and upgrading of Jahloot to 220kV. The upgrade of the 132 kV double circuit line between Dank and Al Hail grid station will be completed by 2013. Further upgrading projects are also required at Izki grid station from 2x40MVA to 2x125MVA transformers, Mudhaibi grid station from 2x63MVA to 2x125MVA transformers, Dank grid station from 2x15MVA to 2x63MVA transformers and Rustaq grid station from 2 x 63 MVA to 3 x 125 MVA tarnsformers. Sur power station Phase-1 220kV GIS installation is scheduled to be completed to meet the system demand in 2013. The main investment to meet the 2013 peak is in the extension of the 220 kV transmission systems from Misfah to Jahloot and on to Hamriyah (Wadi Adai-2) and Sur grid stations. To cater for future growth in demand, consideration is being given to constructing Sur-Jahloot line for operation at 400 kV, but operating initially at 220kV. The other major projects planned for completion before summer 2013 are the new 220/132 kV, 2 x 500 MVA grid stations to be established at Sur, Al Hamryah and Jahloot. 5.2.3 Projects expected to be completed to meet the 2014 peak demand Figure 3 shows in geo-schematic form the system development plan to meet the 2014 system peak demand. The new projects scheduled for completion in time to meet the summer peak demand in 2014 are at various stages of development and the major projects for which a consultant has been appointed for construction. The projects designed to meet the 2014 system demand include the construction of new 132/33 kV grid stations at Ghala (Madinat Al Arfan), Buremim-2, adding third and fourth transformers at Sohar, Madinat Nizwa, Al Kamil & Al Wafi, Madinat Barka, Al Amerat, Mabellah-2 (Al Khoudh) and Al Khadra. Other projects that are required to meet the 2014 system demand are replacement of 132kV GIS at Rusail, replacement of 132KV AIS to GIS at Mahadh (Al Wasit), adding two 220kV GIS bays at Mahadah (Al Wasit) grid station to connect the GCC link between Oman and UAE, linking Al Falaj, Muttrah and Wadi Kabir grid stations by one circuit, new 400kV overhead line between Sur Power Plant Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 34 and Izki 400/220/132kV grid station. Further upgrading projects are also required at Sumail and Shinas grid station from 2x63MVA to 2x125MVA transformers. The other major project planned for completion before summer 2014 is replacement of 132kV Seeb- Mawalleh overhead line to underground cable and adding new 132kV GIS at Mawalleh to connect Seeb Main and Airport Heights grid stations and adding fourth transformer of 125MVA capacity at Mawalleh grid station. Another major project planned for operating the 220 kV line between Jahloot and Sur grid station to 400 kV with the new 400/220 kV gird stations to be established at Jahloot and Sur. This line is planning to operate to 400 kV to evacuate the full power from Sur power plant (2000 MW). 5.2.4 Projects expected to be completed in time to meet the 2015 peak demand Figure 4 shows in geo-schematic form the system development plan to meet the 2015 peak demand. One of the major projects expected to be connected to the transmission system by summer 2015 is the construction of new 132kV grid station at Free Zone, Ibra, Hajarmat, adding third and fourth transformers at MIS and Muladah, upgrading MSQ from 132kV to 220kV and adding fourth transformer of 125 MVA capacity at MSQ grid station (MSQ-B), adding fourth transformer of 125MVA capacity at Wadi Kabir grid station (Wadi Kabir-B), upgrading Liwa to 220kV and new 400kV Overhead lines between Izki and Misfah with 400kV GIS, 400/220kV at Misfah grid station. 5.2.5 Projects expected to be completed in time to meet the 2016 peak demand Figure 5 shows in geo-schematic form the system arrangement to meet the 2016 peak demand. A project expected to be connected to the transmission system by summer 2016 are converting 132kV OHL Nizwa- Ibri to 220kV in addition to 220kV Overhead line to Izki grid station and new 220kV grid station connected to Mobailah-1 by LILO Filaj-Airport Heights OHL. 5.3 Summary Table 1 in the Executive Summary has summarised the development plans for the OETC Transmission System on a project by project basis at the time of this Statement. The table identifies the projects to which OETC are already committed and those projects that are considered likely to proceed. The power system studies presented later in this Capability Statement to show the expected performance of the transmission system over the period 2012-2016 have been performed on the basis that the committed and planned development projects in Table 1 and detailed in Appendix A will proceed as planned and to be completed on schedule. The system studies are used to identify areas of the transmission system where there are opportunities for connecting new demand and new generation and where constraints should be applied to further development.

The planned retirements are as follows: a) Ghubrah Power and Desalination Plant In 2013, it is planned to retire the existing units GT1-9 (144 MW). In addition, ST4 (37 MW), GT10 (26.3 MW) and GT11 (26.3 MW) will be retired in 2014. b) Wadi Jizzi Power Station In 2015, it is planned to retire the existing units GT4 (29.8 MW), GT5 (29.8 MW) and GT8 (29.1). 6.3 Planned future generation (2012 – 2016) There are three main generation developments planned for the period 2012 to 2016: a) Barka III Power Station (IPP) Barka III Independent Power Plant (IPP) has been commissioned recently. There are two gas turbines of 247.5 MW capacity each are available in 2012 and a steam turbine of 249.9 MW capacity which will be available in 2013. The total net generation capacity will be 744.9 MW in 2013. b) Sohar II Power Station (IPP) Sohar II Independent Power Plant (IPP) has been commissioned recently. There are two gas turbines of 247.5 MW capacity each are available in 2012 and a steam turbine of 249.9 MW capacity which will be available in 2013. The total net generation capacity will be 744.9 MW in 2013. c) Sur Power Station (IPP) Sur Independent Power Plant (IPP) will be commissioned in 2013 and 2014. There are five gas turbines of 244MW capacity and only two (217MW each) will be available in 2013. In 2014 the total capacity will reach 2000MW working in a combined cycle with two steam turbines of 311MW and one steam turbine 157MW. Table 3 summarises the net capacity of the additional future generating plant over the period 2012 to 2016 assumed in this Capability Statement. The table shows that an additional 3500 MW of generating capacity from these plants is planned to be in service before the 2014 peak.

The largest generating plant among these is Sohar Aluminium, which may export up to 300 MW. The interconnected system and the private customer generating plants can with the customer’s agreement be made available to support the contracted generation under emergency conditions in order to avoid power cuts in northern Oman because of a shortfall in the contracted generation. These generators are termed “non-contracted” generating plants.

The interconnection connects Mahadah grid station (Al Wasit) to Al Foah grid station in Al Ain in the UAE. The interconnection is via a 220 kV double circuit overhead transmission line with twin Araucaria. In the longer term the principal technical benefit to be obtained from connecting Oman to the GCC Grid is in a reduced spinning reserve requirement, which will be shared between the members of the GCC Grid. However, operation of the interconnection will allow Oman to import/export power from the GCC Grid to meet any potential generation shortfall. 6.5.2 Interconnection with PDO The OETC transmission system is interconnected with the transmission system of the Petroleum Development Oman (PDO) which provides electricity to its sites across the central region of Oman for the purpose of oil exploration and development. The interconnection is made at 132 kV between Nizwa grid station on the OETC system and Nahda 132 kV substation on the PDO 132 kV network by a 67 km Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 47 overhead line with a single Elm. The over head line is owned by PDO. Under normal conditions the power transfer between the two networks is allowed to float around zero MW, with power transfers balanced out over a period. The interconnection essentially allows OETC and PDO to share spinning reserve and supply limited power to each other in emergency conditions on either system. 6.6 Economic Dispatch The Load Dispatch Centre of OETC dispatches generation based on its availability as stated by the Generator on a day-ahead basis, and its price as listed by the Oman Power and Water Procurement Co. (OPWP). Under circumstances where the system frequency is seen to stray outside the specified limits, LDC will issue dispatch instructions to Generators based on Merit Order to rectify the situation. 6.7 Spinning Reserve The Load Dispatch Centre strives to maintain a spinning reserve equal to the rating of the largest generating unit connected to the transmission system. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 48 7. Demand Forecast and Generation Availability 7.1 System Demand Maximum demand usually occurs on the OETC transmission on a weekday in the months of May, June or July, during a period of particularly high temperature and humidity. The growth in air conditioning equipment in domestic and commercial premises in Oman has ensured that peak demand usually occurs during the afternoon. Figure 6 shows the 24-hour demand profile for the transmission system on the day of the 2011 system peak demand (i.e. 18/06/2011). The 2011 system peak demand of 4000.3 MW was recorded at 15:00 hours by the OETC Load Dispatch Centre. The historic growth in system peak demand over the period (2003-2011) is shown in Table 6.

In 2011 the system minimum demand was 909 MW and this occurred on 8 January 2011 at 04:00 AM. The 2011 system minimum demand was 22.72 % of the 2011 system peak demand. The 24-hour profile for the day of minimum demand is shown in Figure 7. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 50 Figure 7: OETC System Load on 2011 Minimum Load Day (08/01/2011) 7.2 Demand Forecast Under clause 3 of Condition 27 of the OETC Transmission and Dispatch Licence it is stated that: “The Licensee shall, when preparing the Capability Statement …. ensure that the forecasts of electricity flows and loading on each part of the Transmission System are consistent with the prevailing electricity demand forecasts prepared and used by the OPWP for the purposes of the Statement of future capacity requirements required by Condition 5 of the OPWP licence”. The OPWP demand forecast is based on data supplied to them by the three distribution companies (i.e. Muscat EDC, Mazoon EC and Majan EC) and includes demand forecasts for the major customers that are, or will be, directly connected to the OETC transmission system at either 220 kV or 132 kV in their respective supply areas. The distribution company forecasts are provided in terms of: a) The growth in major industrial loads b) The growth in major tourism loads c) The annual domestic growth d) The growth in other major loads 200 400 600 800 1000 1200 1400 1600 1800 2000 L o a d ( M W ) Time (hrs) Min Demand Profile Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 51 The forecasts supplied to OPWP relate to the totals for each distribution company and do not indicate how this load is allocated to the individual grid supply points. The forecast data provided to OPWP does, however, include major future connections and the cumulative increase in load over the seven-year period covered by the OPWP Statement. OPWP has then reviewed this data and taken a view as to the probability that the individual schemes will proceed and if so, the rate at which their load will develop. The outcome of this review is presented as the OPWP Demand Forecast in its Seven-Year Statement. The OPWP Demand Forecast was therefore taken as the starting point for developing the demand forecast presented in this OETC Capability Statement. The OETC forecast, however, is required to identify the future demand at individual grid stations at the system peak for each year over the period 2012 to 2016, since this information is required for the power flow studies. Analysis of the demand forecast data used by OPWP in developing its Seven-Year Statement (2012 – 2018) identified basic annual percentage rates of 12.23% for the growth in peak demand in the Mazoon EC, Muscat EDC and Majan DC supply areas. These rates have been applied to the grid station demands in the respective supply areas as noted by the OETC Load Dispatch Centre at the 2011 system peak (i.e. 18/06/2011, 15:00 hour). The demand associated with major industrial and tourism projects as assessed by OPWP (with diversity taken into account) was then superimposed on to the steady growth in the basic demand to produce a basic forecast. Section 5 identified a number of new grid supply points that are scheduled to come into service to meet the summer peak demands from 2012 onwards. These gird stations will provide load relief to the more heavily loaded grid stations and in some cases supply new loads. The distribution companies’ plans for load transfers from existing grid stations that are heavily loaded to new grid stations are one of the most important elements of the demand forecast. Table 7 summarises the load transfers adopted in the studies based on consideration of what is required and what OETC has considered viable. OETC, however, acknowledges that this aspect of the forecast needs to be improved in future and believes that it would be helpful if distribution companies were to give greater consideration to feasible load transfers when planning their distribution networks, and to develop proposals for load transfers in coordination with OETC. Also, the TSS requirement shall be considered at every GSP and all new requirement shall be indicated clearly as indicated by in the Grid Code.

Transmission System Performance The transmission system data used in the power system studies to determine the system performance over the period from 2012 to 2016 is presented in Appendix B of this document. 8.1 Power Flow and Voltage Profiles The extreme cases of maximum and minimum system demand are used to define the performance of the OETC transmission system when it is most heavily stressed. From the studies of these extreme conditions it is possible to identify where the system is strong and has capacity to spare and, conversely, where it is weak and will need strengthening before new connections could be considered. The peak demand case identifies where there is a risk of overloading, of operation above firm capacity, or of system voltages falling below the voltage limits as defined in the Grid Code. The system data described and presented in Appendix B has been used in a series of load flow studies to establish the performance of the OETC transmission system at peak demand in each year from 2012 to 2016 inclusive. The studies were undertaken on the basis that all circuits and plant will be available at system peak in each of the five years and that the system will be developed in accordance with the plans described in Section 5 of the Statement. The studies also assume that the demand will grow in accordance with the Demand Forecast, which is consistent with that produced by the OPWP and distribution companies, and that sufficient generation will be available from both Contracted and Non- Contracted Generating Plants to meet each annual system peak as indicated in the OPWP latest 7 Year Statement. Table 11 shows the summary of the generating plants power assumed to be in service at peak load in each year of the study from 2012 to 2016. Under peak load conditions it is assumed that capacitive support will be switched on, i.e. capacitor banks at 33 kV grid stations are properly adjusted to provide required reactive power and voltage support. In the studies generator terminal voltage and generator-transformer taps are set to control the voltage on the transmission system at the target busbar to within the allowable limits. A second series of load flow studies were undertaken with the transmission system supplying minimum demand. The minimum demand case identifies where there is a risk of the busbar voltages rising above the voltage limits defined in the Grid Code and where additional generation has to be operated to absorb excess reactive power, since there are no reactors connected to the system. At the system minimum demand, the generation is reduced to a level that provides the necessary margin of reserve capacity that is consistent with the operational practices adopted by LDC to handle minimum load conditions. Table 12 shows the generating plants assumed to be in service at minimum load in each year of the study. For 2012, real data are listed in the table. These actual values have been obtained from the LDC Daily Report of the 2012 minimum load which occurred on the 29 th of January 2012 at 04:00 am. The total generation was 1274 MW on that time, which is about 28.86% of expected maximum summer peak (4415MW). Under minimum load conditions it is assumed that all capacitor banks are switched out and some lightly loaded transmission lines are off to avoid overvoltage due to excessive capacitive reactive power.

System diagrams are showing the results of the peak demand. Load flows have also been produced and are available in Appendix C. The results include the following:  Table C.1 shows the transformer percentage loading of all grid stations at system peak demand.  Table C.2 shows the available spare capacity at each grid station in relation to firm capacity at system peak demand. It should be noted that although spare MVA capacities are available at some individual grid stations, there is no guarantee that all can be exploited simultaneously. Lack of available generation and/or voltage level limits may restrict simultaneous utilization of all spare MVA capacities.  Table C.3 shows the percentage loading of each overhead line and underground cable in the transmission system at system peak demand.  Table C.4 shows the voltage profile at each 400 kV, 220 kV, 132 kV and 33 kV bus-bar at maximum and minimum load.  Table C.5 shows the calculated transmission losses at peak demand.  Tables C.6 and C.7 show the maximum three-phase and single-phase to earth short-circuit fault levels respectively. The principal findings from the power system studies are: Grid Stations Firm Capacities a) All 400/220 kV grid stations developed during 2014 to 2016 will have firm capacities as indicated in table C.1. Moreover, these grid stations will have appreciable amount of spare transformer capacities during the same period and for future needs. b) The existing eight 220/132 kV grid stations have adequate amounts of spare capacity available over the period from 2012 to 2016 to cope with growth in demand. The six new 220/132 kV grid stations that will be commissioned over the period 2013 – 2016 at Jahloot, Al-Hamriyah, Sur, Izki, Liwa and Mobalah, will substantially increase the amount of grid transformer capacity connected to the transmission system to facilitate further development of the transmission system. The 220/33 kV grid station at Blue City consists of two 160 MVA transformers. Azaiba Coast (Wave Project) 132/11kV grid station will remain within its firm capacity during the period 2012 to 2016 and beyond this period. This grid station consists of 3x50 MVA transformers with a firm capacity of 100 MVA. c) The 132/33 kV grid stations show some constraints in 2012 and 2013. For example, at the summer peak in 2012, thirteen out of forty seven grid stations will operate above their firm capacity; this represents about 28% of the total grid stations. None of them will be overloaded. In 2013 to 2016, a number of 132/33 kV grid stations will be upgraded and new ones are Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 63 introduced to remove over firm conditions at some locations. In the period 2014 to 2016 all 132/33 kV grid stations will be operating within their firm capacity. d) The number of out-of-firm grid stations during the period 2012 to 2016 are: - 2012 – 13 - 2013 – 13 - 2014 – 0 - 2015 – 0 - 2016 – 0 This is shown graphically in Figure 8. Figure 8: Number of out-of-firm grid stations during 2012-2016. e) Seven temporary transformers are used in 2012 to mitigate over firm issues and provide additional capacity at some 132/33 kV grid stations. The number of these temporary transformers will decrease to five in 2013, three in 2014-2015 and then to only one in 2016. 0 2 4 6 8 10 12 14 2012 2013 2014 2015 2016 N o . o f O u t - o f - F i r m G r i d S t a t i o n s Years Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 64 f) The number of 132 kV overhead and underground lines operating above firm capacity over the summer peak period 2012-2016 will be as follows: - 2012 – 3 - 2013 – 2 - 2014 – 0 - 2015 – 0 - 2016 – 0 Figure 9 shows the reduction in the number of out-of-firm transmission lines during the study period 2012-2016.

In fact, the voltage at all 33 kV busbars is well regulated to be within around 1.0 p.u. in all cases by exploiting the automatic on-load tap-changer of the 132/33 kV transformers and the capacitor banks regulators. k) Figures 10 and 11 show samples of voltage profiles at Airport Heights and MSQ grid stations. These grid stations have three voltage levels: 220 kV, 132 kV and 33 kV. Although the voltage at 220 kV and 132 kV busbars can change within the allowable range (depending on the load), the voltage at the grid supply points is well regulated at almost 33 kV level (1.0 p.u.).

The average power loss is about 1.47%, which is well within international norms. Figure 12: Transmission power losses at peak demand of the years 2012-2016. Load Growth m) The high growth rate of the existing load coupled with major new industrial developments in Sohar and major tourism projects around the coast to the east and west of Muscat presents a major challenge to OETC in providing the capacity needed to satisfy demand over the next five years. Table C.5 shows that the expected peak load increases from 4332 MW in 2012 to 5889 MW in 2016; which amounts to an increase of about 36% during the study period. Figure 13 shows the expected peak load growth from 2012 to 2016. This peak load includes grid, industrial, auxiliary and desalination loads, but excludes transmission losses. 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 2 2012 2013 2014 2015 2016 % o f P o w e r L o s s Years Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 69 Figure 13: Peak load growth over the period 2012-2016. n) The load flow studies show that the planned 400 kV, 220 kV and 132 kV transmission developments will add substantial new capacity to the transmission system that will enable the transmission system as a whole to cope with new demand in compliance with the Transmission Security Standard. Consequently opportunities for the connection of new load should be available where spare capacity exists. 8.2 Fault levels a)- Three-Phase Short Circuit Studies The maximum 3-Phase and Single-Phase short-circuit fault levels have been determined in accordance with IEC 60909 and as such the calculation excludes the contribution to fault level from sources at lower voltages, e.g. from induction motors connected at 11 kV or below. The method is valid and consistent with that followed by other transmission companies in the absence of data from the distribution companies for short-circuit back-feeds to the grid station 33 kV busbars. Table C.6 summarises the results of the 3-phase fault studies over the period 2012-2016: a) All of the 400 kV busbars have fault levels within the corresponding switchgear ratings. b) All of the 220 kV busbars have fault levels within the corresponding switchgear ratings. c) All the 132 kV buses have fault levels within the corresponding switchgear ratings. 0 1000 2000 3000 4000 5000 6000 2012 2013 2014 2015 2016 P e a k L o a d G r o w t h ( M W ) Years Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 70 d) The 3-phase short-circuit level at all 33 kV busbars does not exceed the switchgear rating. b)- Single-Phase Short Circuit Studies Table C.7 summarises the results of maximum single-phase short circuit studies for years 2012 to 2016. In the years 2012 to 2016 the fault levels across the transmission system are within the corresponding switchgear short-circuit ratings. During 2012, busbar splitting at Ghubrah in addition to Rusail will be adopted to reduce fault level to be within existing switchgear ratings. In 2013, splitting will be implemented at New Ghubrah grid station only. In 2014 and 2016 there will be no need to apply the splitting technique at any busbars in the system. All busbars will be operating normally without the need for splitting. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 71 9. Development Opportunities From the results of the load flow and fault level studies, and from analysis of the magnitude and location of generation and demand on the transmission system it is possible to give some indication as to where future generation and demand can be connected to the transmission system without causing or exacerbating any critical technical issues. 9.1 Review of the generation versus load balance on an area basis The performance of the transmission system is affected by the transfer of power, both real and reactive, from one region to another. Large power transfers between regions over long distances increase the voltage drop across the transmission system. They also increase the power losses and reduce the efficiency of the system. Ideally if the balance between generation and demand is maintained on a regional or area basis then power transfers over long distances can be minimised, thus leading to improvement of the transmission system efficiency and voltage regulation. Figure 14 shows the connectivity of the OETC transmission in 2016 as it extends over the northern regions of Oman, a distance of around 500km from Shinas in the North West to JBB Ali in the south-east. To assess how generation and load is distributed over the transmission system the whole supply area has been split into seven geographic areas: a) Muscat b) Al Batinah South c) Al Batinah North d) Al Bureimi e) Al Dhahirah f) Al Dakhiliah g) Al Sharqiyah Table 13 compares the generation capacity installed in each of the seven areas with the forecast demand at the grid station at the annual system peak over the period 2012 to 2016. Muscat area, although geographically the smallest area, is by far the most heavily populated, with the highest demand (1635.4MW in 2012, rising to 2188.7MW in 2016) and with limited amount of connected generation (1134MW in 2012, falling to 902MW in 2016). This will result in power deficits of 501MW in 2012 and 1287MW in 2016. Muscat area has two power plants; Ghubrah (447MW in 2012, reducing to 215MW in 2016) and Rusail (687MW during the period 2012-2016). Much of the generation currently operating at Ghubrah is the most inefficient in the system. The oldest and inefficient generating units at Ghubrah will be retired in 2013 and 2014, reducing Ghubrah generation to less than 50% of its available capacity of 2012. Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 72 Al Batinah South area covers the coastal strip between Barka on the western outskirts of the Muscat area and Sohar. This area is likely to develop as Sohar port grows, since the main road link between Muscat and Sohar runs through it. It also has been chosen for the Blue City Development which is a major residential and tourist development. Currently, there are three power plants in Al Batiniah South; Barka Phase-I (434MW), Barka Phase-II (681MW) and Barka Phase-III (495MW). As shown in table 13,the load in this area rises from 559.6MW in 2012 to 774.2MW in 2016. The power surplus increases from 1051MW in summer peak 2012 to 1078MW in summer peak 2016. Al Batinah North area is rapidly developing around the new port at Sohar with new industry seeking connections to the OETC transmission system or the distribution system of the Majan Electricity Company. Some of the larger industrial customers in the area, such as Sohar Aluminium Company and Sohar Refinery Company operate their own generating plant and on occasions supply power to the transmission system on a non-contracted basis. The load in Al Batinah North area significantly increases from 829.6MW in 2012 to 997MW in 2016, as shown in table 13. Al Batinah North area has two power plants; Sohar-I (434MW during the period 2012-2016) and Sohar-II (495MW, 745MW, 742MW, 740MW and 739MW in 2012, 2013, 2014, 2015 and 2016 respectively). This will result in power deficits of 68MW in 2012.The generation surplus in 2013, 2014, 2015 and 2016 will be 217.2MW, 252.4MW, 200.3MW and 176MW respectively. The transmission system in the Al Bureimi area provides the interconnection with the UAE (Abu Dhabi Transco) and supplies a number of grid stations that feed the Majan distribution system to supply a number of small towns and villages in this remote area. Wadi Al Jizzi power plant is the only generation in Al Bureimi area with power capacity of 245MW in 2012, 2013 and 2014 respectively reducing to 157MW in 2015, and 2016 due to retirement of old inefficient generating units starting from 2012 through 2016. In 2012 the generation surplus is 103.4MW decreasing to 83MW, 72MW in 2013, and 2014 respectively. In 2015 and 2016 the deficiency in generation will be 25.1MW and 45.5MW respectively. Al Dhahirah has no local generartion while the load in this area significantly increases from 156.6MW in 2012 to 179.2MW in 2016, as shown in table 13. Power is transmitted from Wadi Al Jizzi generating plant over about 160km to supply the grid stations at Ibri, Dank and Al Hail. However, the development plan for the period 2012 – 2016 will see the extension of the 220kV systems from Al Wasit in Bureimi area to Ibri and this should produce a remarkable improvement in the voltage quality. Al Dakhiliah area with its provincial load centres is exhibiting a moderate growth and has a local generating power plant at Manah (273MW) connected to the 132kV transmission system. A connection between OETC and PDO is available in the area through the 132kV Nizwa-Nahada transmission line. Power of 60MW maximum can be exchanged between OETC and PDO systems with an annual zero balance. The deficiency in generation rises from 120.2MW in 2012 to 229.1MW in 2016. Al Sharqiyah area has provincial load centres that are exhibiting moderate growth up to 2013. However, a huge industrial load of 300MW is expected to be requested in 2015 by the Sun Metals Company Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 73 (ZOOM). With the existing power station at Al-Kamil (297MW) the power deficiency is 145MW in 2012. In the Sur area a private customer (OMIFCO) has installed generation that can provide support when required again on a non-contracted basis. In 2013 and 2014, Al Sharqiyah area will see a major generation development by building a power plant at Sur having an early power capacity of 433MW by summer 2013 and a total of 2000MW by summer 2014. The power surplus in this area will be 254MW, 1788MW, and 1448MW, 1417MW in 2013, 2014, 2015, and 2016 respectively. Compared to other areas in Oman, Al Sharqiyah area with Sur power plant of 2000MW will have the largest surplus generating power of 1788MW, 1448MW, and 1417MW in 2014, 2015, and 2016 respectively.

Derogation The load flow studies summarised in Appendix C and discussed in Sections 8 and 9 of this Statement indicate a number of out-of firm grid stations and circuits in the early years of the Statement. In this final section, we review each station / circuit, which is currently failing to meet the Transmission Security Standards; we describe the development activities that OETC is undertaking or planning to undertake to address this non-compliance; and we indicate the expected time by which, in each instance, full Transmission Security Standards compliance should be achieved. It should be noted that the Transmission Security Standard on the transmission system would change in future as demand on the system increases and as the system configuration changes. It is possible that further non-compliances might arise in the future until the overall system becomes substantially more robust through interconnection. OETC will keep this situation under review, and the non-compliance status will be updated in the 2013 Capability Statement. As indicated in sections 8, 9, and summarized in tables 15 and 16 (A &B), there are some grid stations and overhead lines, which do not comply with the Transmission Security Standard. Therefore, it will be necessary for a further location and duration specific derogations to be put in place by the Authority for each of the out of firm circuits noted in table 15, and for each of the stations which do not comply with the Transmission Security Standard at peak and maintenance time noted in table 16 (A) and 16 (B) respectively. The following points should be noted: 1- The loading values show in tables C1 and C3 (Appendix C), are those at the peak load conditions. The system peak lasts only for a period of less than one hour in one day during the relevant year. (For example, refer to Figure 6 of 2011daily load curve peak day). 2- According to the most recent OPWP data, there are two forecast cases: (i) expected case, and (ii) high case. The difference between the high and expected case in 2012 is 147 at the peak. This difference increases in the subsequent years and reaches 1078 MW in 2016, indicating uncertainty in the forecast over the coming years especially with regards to new industrial loads. OETC supports OPWP’s view that the likelihood of the high case demands being realized is heavily dependent on the rate of recovery of the current global economic and financial conditions. OETC intends to monitor closely, in coordination with OPWP, the situation in order to assess the probability associated with the high case projection. 3- It is not prudent to invest in uncertain expansion. OETC will, of course, initiate new projects as new demand becomes more certain. Therefore, in Tables 15 and 16 we concentrate on covering the conditions at the peak in 2012. 4- The modelling reflects all load transfer schemes that have been formally accepted by the relevant distribution company and included in their load forecasts. In addition, the modelling includes certain load transfer schemes, which are not yet confirmed by the distribution company concerned, but which Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 88 in the view of OETC are technically feasible and where no technical impediment to implementation exists. OETC has adopted a three-fold approach to addressing these out of firm situations: 1) Reinforcement plans: strategic upgrading to add new circuits and/or to increase the capacity of grid stations within a minimum of two to five years. This will not just solve the problem; but it will also strengthen the transmission system for future development. This type of solution can only be applied as a longer term solution because of the time taken to implement. Reinforcement is the most robust long term solution for secure system development, but may not necessarily be the least cost solution to address the immediate out of firm conditions on the network. 2) Installing third transformers at heavily loaded grid stations, such as MSQ, Mawalleh, Wadi Kabir, Barka Main, Sumail, Ghubrah and Izki. These will provide a temporary solution to the out-of- firm problems at the heavily loaded grid stations until a permanent solution is put in place. 3) Load Transfer: through agreement with distribution companies, load can be transferred from heavily loaded grid stations to more lightly loaded grid stations over the next three years. This would reduce the loading issues and balance the system during peak time. This is a mid-term solution which could be implemented with the cooperation of distribution companies in certain cases. Given the uncertainty of mid-term load forecasts in Oman at present, this is in some circumstances the most appropriate and economic action to address out of firm conditions on the network. Tables 15 and 16 (A) indicate a number of locations on the system where, at present, the out of firm condition of certain circuits or transformers is shown to exist. Table 16 (B) shows the grid stations which are classified as group E (>100 MW) as per the Transmission Security Standard. Some of them will not comply with Transmission Security Standard (Second Outage) at 2012 maintenance period.

Five-Year Annual Transmission Capability Statement (2012 - 2016) Page | 103 Appendix B: Transmission System Data B.1 Substations Loads and Capacitor data. The grid station real and reactive power load at system peak demand for the period 2012 to 2016 and the respective reactive power support from capacitor banks connected at the grid station 33 kV busbars is shown in Table B.1. 1 This data was used in the power flow studies of system peak demand presented in Section 8 of this Capability Statement. B.2 Overhead Line Circuit Capacities and Parameters. The continuous thermal rating of a circuit is the maximum power flow that can be carried by that circuit on a continuous basis. The thermal rating of an overhead line is the power flow that can be carried by that line without infringing the statutory clearances and causing a risk to public safety and to the line itself. The thermal rating of an underground cable, however, is the maximum power flow that the cable can carry without either causing the cable to fail or to effectively reduce its projected lifespan through a deterioration of the cable insulation. Although the thermal rating of an overhead line is affected by climatic conditions, for the purpose of assessing spare capacity on the transmission system the key climatic condition that limits the circuit rating is the summer rating when the temperature is at its highest and the solar radiation is at its peak. This also corresponds to when the electricity demand is at or near to its peak. The circuit data presented in Table B.2 for the first year of the Statement period (2012) comprises the voltage, resistance, reactance, susceptance and thermal rating of the line and cable circuits. It also shows the circuit length and the type of overhead conductor or underground cable for each circuit. Table B.3 shows the changes to the circuit data required in each of the other four years covered by the Statement. B.3 Transformer data The data used to model the grid supply point transformers in the power flow studies of the 2012 summer peak demand condition is listed in Table B.4. The data comprises the transformer voltage ratio, the resistance and reactance, the tap range and step size. Table B.5 lists changes to the transformer data for the remaining four years of the Statement. 1 The 33 kV busbars at the grid supply points and the capacitors connected to them are owned and operated by the distribution companies.
