are subsidiaries of Singapore Power Ltd. SPSL provides support services for the electricity market. It receives requests for electricity service connection; offers terms and conditions of service connection; arranges for service connection energisation/turn-on; and collects transmission charges, security deposits and charges for other services on behalf of PowerGrid. SPSL also bills customers for consumption. PowerGrid develops, operates and maintains transmission and distribution facilities. 1.1.2 The supply of electricity and electrical installation practices are governed by the Electricity Act and its subsidiary legislation. 1.2 CONNECTION VOLTAGES AND SUPPLY FREQUENCY 1.2.1 In Singapore, customers’ load installations are connected at the following voltages: 1.2.1.1 Transmission voltage of 66kV and 230kV 1.2.1.2 Distribution voltage of 230V, 400V, 22kV (may vary within ± 6%) The supply voltages are classified in the following categories: 1.2.1.3 Low voltage (LV) refers to 230V, single-phase and 400V, 3-phase 1.2.1.4 High voltage (HV) refers to 22kV 1.2.1.5 Extra high voltage (EHV) refers to 66kV and 230kV L 8 G eneral Inform ation 1.2.2 The following connection schemes are provided, according to customers’ load requirements: 1.2.2.1 230V, 50Hz, single-phase, up to maximum of 23kVA, 100A 1.2.2.2 400V, 50Hz, 3-phase, 4-wire 1.2.2.3 22kV, 50Hz, 3-phase, 3-wire for a Contracted Capacity of: 1.2.2.3.1 between 1,700kW and 12,750kW for 2 HV services 1.2.2.3.2 between 12,751kW and 25,500kW for 4 HV services 1.2.2.4 66kV, 50Hz, 3-phase, 3-wire for connection with minimum Contracted Capacity of 25,500kW 1.2.2.5 230kV, 50Hz, 3-phase, 3-wire for connection with minimum Contracted Capacity of 85,000kW 1.2.3 Where the customer requires a connection voltage and/or frequencies that differ from those specified above, the customer is required to provide, install and maintain the necessary transformation equipment. 1.3 SUBMISSION OF APPLICATION SPSL serves as a one-stop customer service centre. It receives all application forms on behalf of PowerGrid, and responds to all applications made by the Licenced Electrical Worker (LEW), who acts as the customer’s agent for connection to the transmission system. Customers applying for their installations to be connected to PowerGrid’s transmission system must submit their applications through their LEWs. Every application must be accompanied by all supporting documentation requested by SPSL. A copy of the Application Form is shown in Appendix 1. For a development in the conception/planning stage, the customer is advised to seek consultation regarding PowerGrid’s requirements, such as the provision of a substation, for load connection. The Consultation Form (Appendix 2) must be submitted directly to PowerGrid by the customer’s LEW. 1.4 PROVISION OF A SUBSTATION 1.4.1 Direct service connection from PowerGrid’s LV network to the customer’s installation is available for a small load requirement not exceeding 280kVA (400A). However, the provision of a direct service connection is dependent on the available network capacity in the vicinity. If there is insufficient capacity, the customer is required to provide a substation for the connection. L 9 G eneral Inform ation 1.4.2 For a larger load requirement exceeding 280kVA (400A), the customer has to provide a substation for PowerGrid to install necessary equipment to cater for the load. 1.5 DOMESTIC PREMISES AND LOAD REQUIREMENT NOT EXCEEDING 45kVA 1.5.1 For premises where the electricity meter has already been installed by PowerGrid and no extension or rewiring work is required, electricity service connection will be turned-on on the 4th working day from the date of the opening of an account with SPSL. 1.5.2 For premises where there is no electricity meter or where extension or rewiring work is required, the customer has to engage an LEW and submit an application for load connection (See Section 2). 1.6 METER All meters required for measuring a customer’s electricity consumption and demand (where applicable) are provided and maintained by PowerGrid. The customer provides meter boards, compartments, kiosks etc, as PowerGrid may require for the installation of its metering equipment. 1.6.1 Master- And Sub-Metering A “Master-meter” is a meter measuring the consumption for all units and common areas in a building or cluster of buildings which are used or occupied by multiple consumers. A “Sub-meter” is a meter measuring the consumption for a unit in a building or cluster of buildings used or occupied by multiple consumers, whose electricity is taken through a Master-meter. 1.6.1.1 Multi-Metered Premises The following are categories of multi-metered premises: 1.6.1.1.1 Residential premises which have landlord and tenant supply connections 1.6.1.1.2 Commercial complexes which have landlord and tenant supply connections 1.6.1.1.3 Multi-storey factories or industrial complexes which have landlord and tenant supply connections 1.6.1.1.4 All multi-metered premises fall under the Master- and Sub-metering scheme, with the exception of HDB residential premises. L 10 G eneral Inform ation 1.7 TARIFFS FOR NON-CONTESTABLE CUSTOMERS 1.7.1 Tariffs are currently charged for low tension, high tension and extra high tension electricity consumption. 1.7.2 Tariffs are subject to change and are published by SPSL from time to time. Onl i ne i nformati on on the l atest el ectri ci ty tari ffs are avai l abl e at www.spservices.com.sg. 1.8 PAYMENT FOR ELECTRICITY CHARGES BY CONTESTABLE CUSTOMERS Contestable customers pay to SPSL or authorised retailers, charges for electricity consumption as ascertained by meters, and transmission charges and other fixed charges as determined by SPSL. Payment for electricity charges must be made on or before the due date specified in the bill. 1.9 OPENING ACCOUNT AND PAYMENT OF SECURITY DEPOSIT FOR USE OF SYSTEM (UOS) CHARGES The customer must open an account and place a security deposit for UOS charges with SPSL upon application for energisation of service connection. 1.10 TERMINATION OF ACCOUNT Non-contestable customers must give 4 business days’ notice and contestable customers must give 12 business days’ notice to terminate an account. Such notices must be in writing. 1.11 DISCONNECTION OF SERVICE CABLES Disconnection work involves the de-energisation and removal of service cables and equipment (See 4.9.6). The following are indicative lead-times for the work: 1.11.1 For disconnection and removal of LV service cables where road-opening work is not involved, the lead-time is about 5 business days. Where road opening work is involved, a lead-time of 1 month is required. 1.11.2 For disconnection of 6.6kV and 22kV where removal of service cables and equipment are involved, the lead-time is about 1 month. 1.11.3 For disconnection of 66kV and 230kV service cables, the service cable and equipment are de-energised within 10 business days, subject to the approval of the Power System Operator (PSO). The subsequent removal of service cables and equipment will depend on the operational requirement and approval of the PSO. L 11 A pplication For Load C onnection 2.1 DISTRIBUTION CONNECTION 2.1.1 Introduction Each premises can have only one customer’s intake connection point. For modification of connection (such as upgrading of the load requirement) to existing premises, the customer is required to amalgamate the existing service connection into one intake. 2.1.2 Consultation For a development in the initial planning stage, the customer is advised to seek consultation with PowerGrid to ascertain PowerGrid‘s requirements for a new or modified connection to the transmission system. The LEW is required to submit the Consultation Form (Appendix 2), together with a site/ location plan to PowerGrid. After receipt of the submission for consultation, PowerGrid will send a reply stating the approved load and other technical requirements, such as the provision of substation requirements necessary for the load connection to the transmission system. 2.1.3 Application The Application Form (Appendix 1), together with a copy of the site/location plan, must be submitted to SPSL by the LEW for new or modified connections of new or existing premises to the transmission system. Application For Load Connection 2 L 12 A pplication For Load C onnection 2.1.3.1 Processing Of Application Generally, SPSL responds to applications within 10 business days. The responses are made according to the following customer categories: 2.1.3.1.1 Contestable Customer – A Consumer Connection Agreement, containing the service connection charge payable, the offer letter and the standard terms and conditions with respect to the distribution service connection. – If a substation is required, a letter stipulating the requirements will be forwarded to the customer, and an Agreement offered after the substation’s plans are endorsed. 2.1.3.1.2 Non-Contestable Customer – A Quotation, containing service connection charge payable and the conditions of service with respect to the distribution service connection. – If a substation is required, a letter stipulating the requirements will be forwarded to the customer. A Supply Agreement, including the service connection charge payable and the terms and conditions with respect to the distribution service connection, is offered after the substation’s plans are endorsed. 2.1.3.2 Commencement Of Work – PowerGrid commences work only when the Agreement has been signed and received by SPSL, together with payment of service connection charges. 2.1.4 Types Of Premises 2.1.4.1 Multi-Metered Premises 2.1.4.1.1 A multi-metered premises is one where the landlord/MCST (i.e. a master- metered consumer or directly connected consumer) receives bulk intake service connection from PowerGrid, and transforms/reticulates the supply to all the tenants (i.e. sub-metered consumers) within the premises. Any application for new or modified connection (including upgrading) for the bulk intake to the multi-metered premises must be made by the landlord through its LEW. A master-metered consumer means a consumer that is responsible for the common usage of a master-metered installation which is connected to the transmission system. A master-metered installation means an installation in which supply is received by a master-metered consumer and sub-metered consumers. L 13 A pplication For Load C onnection A sub-metered consumer means a consumer, other than a master-metered consumer, that receives supply in a master-metered installation via the electrical system owned by a master-metered consumer. 2.1.4.1.2 The landlord/MCST or HDB, in the case of HDB premises, must ensure that the total applied load requirement for service connections to the multi- metered premises meet the total existing and future load requirements for all tenants. All tenants applying for any upgrading of load must do so through their master-metered consumer. In this regard, the master-metered consumer must approve the load of all tenants within the premises. 2.1.4.1.3 If the landlord’s existing approved load is insufficient to cater for the tenants’ load requirement, the landlord, as a master-metered consumer, must submit an application to SPSL for modification (upgrading) of service connection to the exi sti ng premi ses. In thi s case, the exi sti ng servi ce cabl es are amalgamated with the new intake. Hence, there will not be separate direct connections to the tenants of such premises. 2.1.4.2 Premises In Private Housing, Industrial Estates, Commercial Developments Requiring Provision Of Low Voltage (LV) Distribution Network 2.1.4.2.1 For connection to premises where several parcels of land are to be sold or leased individually, one or more substations must be provided by the developer. Where the individual parcels of land are to be sold prior to development of these substations, details of the substation requirements and approved load must be included in the sales agreement by the future land parcel’s owner or lessee. 2.1.4.2.2 The developer must provide the development’s total load requirement and include the breakdown of the individual premises’ load requirement (as specified in the sales agreement) and the communal load requirement, if applicable. 2.1.4.2.3 In the case of landed housing estate development, the LEW must liaise with National Parks Board for the siting of overground distribution boxes on turfed areas. PowerGrid will provide and install the LV distribution network and service connection cables for the development. 2.1.4.3 Premises Involving Temporary Connection With Provision Of Substation 2.1.4.3.1 Special terms and conditions apply in such cases for temporary connection to construction worksites and other temporary premises. The term granted for temporary connection is usually 24 months. 2.1.4.3.2 Where there is a need for the provision of a temporary substation, the customer must provide the site and construct the structure of the substation according to the requirements of PowerGrid. L 14 A pplication For Load C onnection 2.1.4.3.3 There will be a need to install the necessary cables and equipment to facilitate the temporary connection to the distribution network. The customer pays outright costs for the cables and a monthly hiring charge for the use of the equipment (including the cost of insuring the equipment) during the term for temporary connection. 2.1.5 Provision Of Substation 2.1.5.1 When an application for load connection necessitates the provision of a substation (See Appendices 9 & 10), a site must be provided and a substation constructed by the customer at its own cost. 2.1.5.2 The customer is advised to site the substation at an inconspicuous location, away from the main entrance of the development and major public roads. The customer is also encouraged to harmonise, blend and integrate the substation with its development. 2.1.5.3 PowerGrid’s officers and vehicles will have full and unrestricted access to the substation. 2.1.6 Types Of Service Connection Cables The types of cables for service connection is shown in Appendix 36. In the event that the customer is required to supply and install the cables, the customer’s LEW has to seek consent from PowerGrid if the cables are different from the list shown in Appendix 36. 2.2 TRANSMISSION CONNECTION 2.2.1 Consultation 2.2.1.1 A customer may choose to seek preliminary comments from PowerGrid via the connection consultation process before submitting a formal application. This practice is encouraged as incorporating PowerGrid’s requirements in a developer’s preliminary proposal would expedite the application process at a later stage. 2.2.1.2 To initiate the connection consultation process, the customer has to submit the Consultation Form (Appendix 2) through an LEW to PowerGrid. L 15 A pplication For Load C onnection 2.2.2 Application The following are steps in the application for service connection: 2.2.2.1 The customer submits the Application Form (Appendix 1) through an LEW to SPSL. 2.2.2.2 A connection proposal, duly endorsed by the PSO, is given to the customer. It outlines the connection scheme, connection voltage, connection equipment and facilities required of the customer and the estimated connection charges. PowerGrid endeavors to respond to the customer, through SPSL, within 60 business days and 100 business days for 66kV connections and 230kV connections respectively. 2.2.2.3 Where the application requires the provision of an EHV substation, the customer must adhere to the general requirements attached in Appendix 17. 2.2.2.4 Once the customer acknowledges acceptance of PowerGrid’s connection proposal , PowerGri d proceeds to execute the Consumer Connecti on Agreement through SPSL. The Agreement contains an offer letter, the standard terms and conditions associated with the connection and an estimation of the connection charges. 2.2.3 Lead-Time For Application Of Transmission Connection 2.2.3.1 The timely provision of electricity supply to a development involves the joint efforts of SPSL, PowerGrid, and the customer and their agents, such as the LEW. While SPSL and PowerGrid will make every effort to engineer and implement the connection scheme, it is at the same time essential for the new customers and their agents to co-operate via timely submission of applications and plans, timely acceptance of the terms and conditions of connection and compliance with the necessary PowerGrid or Transmission Code requirements. L 16 A pplication For Load C onnection 2.2.3.2 As a guide for the customer and their agents, the normal lead-times for the events leading to the energisation of 66kV service connections are listed in the box below. The actual lead-time to energisation may vary for each connection, depending on the actual service cable length and the progress of intermediate events leading to completion of service connection works. Customers will be informed accordingly either at the point of application or at any time a review is required. For 230kV service connections, the customer will be informed of the lead-time only at the point of application. NORMAL LEAD-TIME FOR ENERGISATION OF 66kV SERVICE CONNECTION New 66kV Connection New 66kV Connection from New 66kV Substation from PowerGrid’s Provided by Connection Events Existing Substation Applicant From day of execution of Consumer Connection 21 months 26 months* Agreement to energisation of service connection Note: * The customer is required to handover the substation 8 months prior to target date of energisation of service connection. L 17 Transm ission C harges 3.1 CONSUMER CONNECTION AGREEMENT 3.1.1 All customers are required to enter into a Consumer Connection Agreement with PowerGrid and to pay Use of System (UOS) charges. Customers having a direct connection to the transmission system must also pay a service connecti on charge. For non-contestabl e customers, the Connecti on Agreement is part of the Supply Agreement. 3.1.2 The Consumer Connection Agreement for customers taking HV supply at 6.6kV/22kV or EHV supply at 66kV/230kV will, inter alia, state the Contracted Capacity, which is deemed to be the requirements for a period of five years. Customers cannot reduce their Contracted Capacity until the expiration of the 5-year period or additional 5-year period. Further, a customer who terminates the supply agreement during the 5-year period or additional 5- year period will be required to pay PowerGrid through SPSL/Retailer, the Contracted Capacity Charge for the unexpired portion of the 5-year period. 3.1.3 UOS charges are payments for the use of the transmission services. The UOS charges are paid for electricity consumption at each metered intake supply point in accordance with the voltage at which a customer receives the electricity supply. 3.1.4 In the case of HV and EHV supply to multi-metered premises, the landlord has to enter into a Connection Agreement for the network capacity required for his own load only – i.e. supply for common services, etc. Transm ission Charges 3 L 18 Transm ission C harges 3.2 USE OF SYSTEM (UOS) CHARGES FOR NON-CONTESTABLE CUSTOMERS 3.2.1 UOS charges for non-contestable customers are included in the electricity tariffs offered by SPSL. The types of tariffs currently available are for low tension (LT: 400V/230V), high tension (HT: 22kV and 6.6kV) and extra high tension (EHT: 66kV). 3.2.3 Low Tension (LT) Supply LT customers pay charges based only on energy (kWh units) supplied to an installation. The supply is charged at a flat rate for each kWh delivered at each metered intake supply point. 3.2.4 High Tension (HT)/Extra High Tension (EHT) Supply HT and EHT customers pay charges calculated from tariffs based on the Contracted Capacity Charge, Usage Charge, Uncontracted Capacity Charge and Reactive Power Charge. 3.2.4.1 The Contracted Capacity Charge payable by customers to SPSL is based on kW Contracted Capacity. The Contracted Capacity Charge is calculated as follows: Contracted Capacity Charge = Customer’s Contracted Capacity x Contracted Capacity Rate 3.2.4.2 The Usage Charge payable by the customers to SPSL is based on kWh of electricity supplied. The Usage Charge is calculated as follows: 3.2.4.2.1 For Peak Period Usage Charge = kWh consumed during the Peak Period x Peak Period Rate 3.2.4.2.2 For Off-Peak Period Usage Charge = kWh consumed during the Off-Peak Period x Off-Peak Period Rate 3.2.4.3 The Uncontracted Capacity Charge, which is based on the customer’s excess kW demand, is payable if in any month the customer’s actual kW maximum demand exceeds its Contracted Capacity. The Uncontracted Capacity Charge is calculated based on the following: Uncontracted Capacity Charge =(kW maximum demand – Contracted Capacity) x Uncontracted Capacity Rate L 19 Transm ission C harges 3.2.4.4 The Reactive Power Charge, which is based on the customer’s excess kVArh, is payable if in any month the customer’s kVArh consumption exceeds 62% of its kWh consumption. The Reactive Power Charge is calculated based on the following: Reactive Power Charge =(kVArh – 62% of kWh) x Reactive Power Rate 3.3 USE OF SYSTEM (UOS) CHARGES FOR CONTESTABLE CUSTOMERS Contestable customers pay UOS charges for transmission services at each metered intake supply point in accordance with the voltage at which the customers receive the electricity supply. UOS charges are subject to change and these changes will be published by PowerGrid from time to time. 3.3.1 Low Tension (LT) Supply LT supply is metered on energy (kWh units). LT supply for contestable customers attract UOS charges based onl y on energy suppl i ed to an installation. The supply is charged at a flat rate for each kWh delivered at each metered intake supply point. 3.3.2 High Tension (HT), Extra High Tension (EHT) And Ultra High Tension (UHT: 230kV and above) Supply For HT, EHT and UHT supply, each metered intake supply point attracts its own UOS charges as follows: a) a Contracted Capacity Charge, b) a Peak Period Charge, c) an Off-Peak Period Charge, d) a Reactive Power Charge, and e) (i) an Uncontracted Capacity Charge, and (ii) an Uncontracted Standby Capacity Charge (only for customers with embedded generation who opt to cap their demand drawn from the network). L 20 Transm ission C harges 3.3.2.1 Contracted Capacity Charge 3.3.2.1.1 The Contracted Capacity Charge is a monthly charge for the Contracted Capacity at each metered intake supply point of a customer. The Contracted Capacity of a metered intake supply point is the total supply capacity in kW requested by the customer. 3.3.2.1.2 For a new supply, the Contracted Capacity is deemed to be the customer’s requirement for a binding period of 5 years. This period starts from the target date or the date PowerGrid’s plant and equipment, except for the service cable, are available to provide such Contracted Capacity, whichever is the later. For new HT, EHT and UHT supply, the minimum Contracted Capacity for each metered intake supply point shall be as follows: HT with 1 or 2 feeders 1,700kW HT with 3 or more feeders 12,750kW EHT 25,500kW UHT 85,000kW For new supply, a request may be made for intermediate steps before the full Contracted Capacity is implemented during the first year of the 5-year binding period. The first step will be at least one quarter of the customer’s full Contracted Capacity at each metered intake supply point. 3.3.2.1.3 After the 5-year period, the Contracted Capacity at each metered intake supply point may be reduced subject to the following minimum values: HT with 1 or 2 feeders 850kW HT with 3 or more feeders 6,375kW EHT 12,750kW UHT 42,500kW Any revision of the Contracted Capacity after the 5-year period will apply for a minimum binding period of 1 year. 3.3.2.1.4 For a new development with landlord and tenants, the supply capacity required by the landlord himself must meet the minimum values set out in 3.3.2.1.2 and 3.3.2.1.3 above in order for the landlord to qualify for HT or EHT supply. 3.3.2.1.5 Upward revision of the Contracted Capacity may be allowed during the validity of the binding period of 5 years or 1 year of the Contracted Capacity. The revised Contracted Capacity in such cases apply for the remainder of the 5-year period or for a minimum period of 1 year, whichever is the greater, provided PowerGrid is not required to install new or additional equipment. Downward revision during a binding period will not be allowed. L 21 Transm ission C harges 3.3.2.1.6 A customer whose revised contracted capacity requires PowerGrid to install new or additional equipment, will be considered as receiving a new supply with a new 5-year binding period. 3.3.2.2 Peak Period Charge The Peak Period Charge payable is the monthly charge based on the energy (kWh units) supplied to an installation during the peak period – from 7.00am to 11.00pm – in that month. 3.3.2.3 Off-Peak Period Charge The Off-Peak Period Charge payable is the monthly charge based on the energy (kWh units) supplied to an installation during the off-peak period – from 11.00pm to 7.00am – in that month. 3.3.2.4 Reactive Power Charge The Reactive Power Charge is a monthly charge for the installation’s excess kVArh consumption. The excess kVArh is the difference by which the installation’s kVArh consumption drawn from the network in that month is greater than 62% of its kWh consumption drawn from the network in the same month. 3.3.2.5 Uncontracted Capacity Charge 3.3.2.5.1 The Uncontracted Capacity Charge applies to customers without embedded generation. It also applies to existing HT and EHT customers with embedded generation whose monthly maximum demand in kW is the maximum summated demand in kW in the month, determined by summating the kW demand from the network and the kW output from embedded generation. 3.3.2.5.2 The Uncontracted Capacity Charge is a monthly charge for the Uncontracted Capacity consumed. The Uncontracted Capacity is the capacity in kW by which the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point, and is chargeable for the month concerned. 3.3.2.5.3 The Uncontracted Capacity Charge is also applicable to existing HT and EHT customers with embedded generation who opt to cap their power demand in kW drawn from the network in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity. The Uncontracted Capacity for these customers is limited to 20% of the Contracted Capacity. L 22 Transm ission C harges 3.3.2.6 Uncontracted Standby Capacity Charge 3.3.2.6.1 The Uncontracted Standby Capacity Charge applies to existing customers with embedded generation who opt to cap their power demand in kW drawn from the network. This charge applies to such customers in the event that their demand in kW exceeds 120% of the Contracted Capacity at that metered intake supply point due to their failure to cap the kW demand drawn from the network. 3.3.2.6.2 The Uncontracted Standby Capacity Charge is a monthly charge for the Uncontracted Standby Capacity consumed. The Uncontracted Standby Capacity is the capacity in kW by which the demand in kW (measured by the power meter) exceeds 120% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds due to their failure to cap the kW demand drawn from the network, and is chargeable for the month concerned. 3.4 TEMPORARY SUPPLY Temporary supply is available only at LT and HT voltages for temporary civil engineering and building construction sites. The UOS charges applicable for the LT and HT temporary supply will be as in 3.2 and 3.3. For temporary supply at HT, the Contracted Capacity applies for a minimum binding period of 1 year. Upward revision of the Contracted Capacity may be allowed during the validity of the binding period of the Contracted Capacity. The revised Contracted Capacity in such cases apply for a minimum period of 1 year, provided PowerGrid is not required to install new or additional equipment. Downward revision during a binding period will not be al l owed. A customer whose revi sed Contracted Capaci ty requi res PowerGrid to install new or additional equipment is considered as receiving a new temporary supply. 3.5 SUPPLY FOR POWER STATIONS The UOS charge for transmission services provided to a power station which draws electricity supply through the generation connection is based only on energy (kWh) units. The UOS charge applies to the sum of the net kWh i mported hal f-hourl y i nto the power stati on through the generati on connection and is based on the connection voltage. The UOS charge for transmission services provided to a power station which draws electricity supply through a separate service connection is the same as for a load and attracts a Contracted Capacity Charge based on the service connection voltage. L 23 Energisation A nd Turn-O n Procedures The term “energise”, in the case of a customer’s installation that is directly connected to the transmission system, refers to the closing of a circuit breaker or other isolating device that is owned and controlled by PowerGrid. “Energisation”, “de-energisation” and “re-energisation” and all grammatical variations of the term shall be interpreted accordingly.

For larger consum ers w ith substations, their supply intake point is usually adjacent to the substation, w hich requires a service cable of approxim ately 15m in m ost instances. Therefore, the standard connection charge is com puted based on a cost of service cable length of 15m . C onsum ers shall pay the additional cost for service cable exceeding 15m . In addition, consum ers shall also pay for those dedicated assets, such as sw itchgear and transform ers, w hich are serving them and do not benefit others. For individual sm all consum ers w ithout substations, the cost of LT service cable for the sam e capacity m ay vary w idely depending on their locations w ith respect to the nearest LT m ains. These consum ers are not the sole beneficiaries of the extension of the LT netw ork. To achieve a greater degree of equity in term s of cost for these general consum ers, a standard cost approach is adopted based on sim ilar requirem ents. The average global cost based on capacity is determ ined from past statistics. A s such, this category of consum ers w hich com prises m ainly the individual landed residential ow ners, applying for the sam e applied load w ould pay the sam e standard connection charge regardless of the location of their prem ises from the existing LT netw ork. Standard charges are only applicable to consum ers w ho are connected to the shared netw ork. The rates, w hich are approved by EM A , are available in the Transm ission Services R ate Schedule. Standard charges are not applicable to consum ers w here the netw ork created is unlikely to be shared by others. Som e of these include supply to H D B prem ises, tem porary w ork sites, public installations and offshore island prem ises. These consum ers w ould have to pay for the full connection netw ork cost, based on user-pay principle, as they are the m ain beneficiaries. 2 Service Connection Charges for HV and EHV Connection C ustom ers receiving H V and EH V connection shall pay the cost of the service connections to their intake equipm ent including cables, associated equipm ent and facilities to effect the connection of custom er’s equipm ent to Pow erG rid’s substation/netw ork. The service connection shall cater for single contingency. C ustom ers requesting for additional level of contingency above single contingency are required to pay for the full cost of such provision. 3 Dedicated Network/Substation The custom er shall pay the full cost for all associated equipm ent and facilities under a dedicated netw ork/substation schem e w hich the netw ork capacity is intended to serve to its developm ent exclusively.
