SP Group starts vehicle-to-grid technology trial � THU, JUL 08, 2021 - 9:24 PM | UPDATED THU, JUL 08, 2021 - 9:35 PM TAY PECK GEK � peckgek@sph.com.sg � @PeckGekBT Jimmy Khoo, chief executive of SP PowerGrid, with the V2G-capable Nissan LEAF and a V2G bi-directional charger that will be used in the Singapore trial. NATIONAL grid operator SP Group (SP) has started its trial of vehicle-to-grid (V2G) technology and has raised its investment in a V2G technology rm as Singapore progresses towards wider adoption of electric vehicles (EVs). The company aims to test the viability of tapping the energy stored in EVs in the trial to enhance the reliability of the grid, which will need to support more than 600,000 vehicles when Singapore phases out internal combustion engine vehicles by 2040, said SP in its media statement on Thursday. When charged, EVs store energy in their lithium-ion batteries, which serve as small energy storage systems that can transfer energy back to balance the power grid, such as when renewable energy sources such as solar power fluctuate due to weather conditions. If V2G technology is viable, owners of EVs can be paid for the use of their batteries when they are tapped to mitigate the intermittency problem in other energy sources. SP has stepped up its investment in the V2G technology rm The Mobility House (TMH), but did not provide the speci cs. SP only stated that TMH has a presence in Munich, Zurich and Belmont (in California) , and provides a non-proprietary software for integrating vehicle batteries into power grids using intelligent charging and storage solutions. SP is providing four V2G charging points at SP's premises for the trial, which will be completed in June 2022. V2G technology allows energy transfer between the batteries within an EV and the power grid, and so is more sophisticated than uni-directional charging of EVs.

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/turnon; and collects transmission charges, security deposits and charges for other services on behalf of SPPA. SPSL also bills customers for consumption. SPPA is the Transmission Licensee and owner of the transmission and distribution network. SPPG, the managing agent for and on behalf of SPPA, develops, operates and maintains the 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. 1.1.3 “Customer” and “consumer” shall have the same meaning in this handbook. 1.2 Connection Voltages and Supply Frequency 1.2.1 In Singapore, customers’ installations are connected at the following voltages: (a) Transmission voltage of 66kV and 230kV (b) Distribution voltage of 230V, 400V, 6.6kV and 22kV (may vary within ± 6%) 1.2.2 The supply voltages are classified in the following categories: (a) Low Tension (LT) refers to 230V, single-phase and 400V, 3-phase (b) High Tension (HT) refers to 22kV and 6.6kV (c) Extra-High Tension (EHT) refers to 66kV (d) Ultra-High Tension (UHT) refers to 230kV 1 1.2.3 The following connection schemes are provided, according to customers’ load requirements. It shall apply to new and existing customers, including customers who are revising their Contracted Capacity. The power factor shall be based on 0.85. (a) Low Voltage, 50 Hz: • 230V, single-phase, up to a maximum of 23kVA, 100A • 400V, 3-phase, 4-wire system, up to a maximum of 5000kVA per substation (b) 22kV, 50 Hz, 3-phase, 3-wire system for a Contracted Capacity: • between 1,700kW and 12,750kW for 2 HT 22kV services • between 12,751kW and 25,500kW for 4 HT 22kV services (c) 66kV, 50 Hz, 3-phase, 3-wire system for a Contracted Capacity: • between 25,501kW and 84,999kW for service connection from the nearest feasible 66kV substation • between 85,000kW and 169,999kW for service connection from the nearest feasible 66kV source station (d) 230kV, 50Hz, 3-phase, 3-wire system for connection with minimum Contracted Capacity of 85,000kW 1.2.4 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 1.3.1 SPSL serves as a one-stop customer service centre. It receives all application forms on behalf of SPPA, and responds to all applications made by the Licensed Electrical Worker (LEW), who acts as the customer’s agent for connection to the transmission system. SPSL may, in its sole and absolute discretion, deal with the customer directly. 1.3.2 Customers applying for their installations to be connected to SPPA’s transmission system must submit their applications through their LEWs. Every application must be accompanied by all supporting documentation requested by SPSL, including a letter of consent as shown in Appendix 1. The applications must be submitted via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg. A user manual can also be downloaded from the website. 1.3.3 For data centre developments, customers will need to include IMDA acknowledgement email as part of application submission. Please refer to Singapore Power (SP) eBusiness Portal for more information. 1.3.4 For developments in the conception or planning stage for a new connection or an upgrade / increase in Contracted Capacity to an existing connection, the customer is advised to seek consultation regarding SPPA’s requirements. This includes considerations such as the provision of a substation, modifications to an existing 2 substation/connection, and lead time required for service connection, which is subject to network availability and includes any network reinforcement that may be necessary to support the intended load connection. The Consultation Form must be submitted by the customer’s LEW via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg. A user manual can also be downloaded from the website. 1.4 Provision of a Substation 1.4.1 Direct service connection from SPPA's LT 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. 1.4.2 For a larger load requirement exceeding 280kVA (400A), the customer has to provide a substation for SPPA 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 SPPA and no extension or rewiring work is required, customer may submit for an opening of utilities account to SPSL directly. Turn on of electricity service connection will happen on customer’s requested turn on date, subject to availability of appointment slots. 1.5.2 For premises where there is no electricity meter or where extension or rewiring work is required, the customer has to engage a LEW and submit an application for load connection. 1.6 Meter 1.6.1 All meters required for measuring a customer’s electricity consumption and demand (where applicable) are provided and maintained by SPPA. The customer has to provide meter boards, compartments, kiosks, etc. as SPPA requires them for the installation of its metering equipment. 1.6.2 Master- And Sub-Metering (a) 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. For master-metering scheme, the common services load must be at least 10% of the total load for the premise. (b) 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. (c) A master and sub-metering scheme is applicable for multi-tenanted premises. Under this scheme, the electricity supply is metered at the intake point and each tenant’s supply is also separately metered and billed under the appropriate tariff. The owner/ developer/ landlord shall be billed for the difference in the consumption between the consumption metered at the intake point and the 3 summated consumption of the tenants. Where the owner/ developer/ landlord takes supply at high tension and is responsible for stepping down the supply to 230V/ 400V for distribution to tenants, a rebate of 2.5 % on the summated consumption of the tenants will be granted. (d) The owner/developer/MCST/landlord is to ensure that the owners (for selfoccupied units) or tenants (as the case might be) of individual units apply for the requisite utility account immediately upon taking possession of such units. The owner/developer/MCST/landlord is to maintain strict access controls over the switchboard, which contains the switches for the electricity supply from the main supply received from the network operator to the individual units at the supplied premises. The owner/developer/MCST/landlord shall be responsible for any charges arising as a result of unauthorised consumption of electricity by individual units or otherwise in the supplied premises. 1.6.3 Multi-Metered Premises The following are categories of multi-metered premises: (a) Residential premises which have landlord and tenant supply connections (b) Commercial complexes which have landlord and tenant supply connections (c) Multi-storey factories or industrial complexes which have landlord and tenant supply connections (d) All multi-metered premises fall under the Master and Sub-metering scheme with the exception of HDB residential premises. 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 quarterly.

Securing of network capacity is achieved by confirmation of Contracted Capacity in Customer Connection Agreement or approval of Revision of Contracted Capacity by the Transmission Licensee. 7 2.3.2 For data centre developments, customers will need to include IMDA acknowledgement email as part of application submission. Please refer to Singapore Power (SP) eBusiness Portal for more information. 2.4 Processing of Application 2.4.1 Generally, SPSL responds to applications within 10 business days. 2.4.2 The responses are made according to the following customer categories: (a) 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. It will be followed by an Agreement subsequently after the substation plans are endorsed. (b) 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 & conditions with respect to the distribution service connection, is offered after the substation plans are endorsed. 2.5 Commencement of Work 2.5.1 SPPG commences work only when the Agreement has been signed and received by SPSL, together with payment of service connection charges. 2.6 Type of Premises 2.6.1 Multi-Metered Premises (a) Multi-metered premises are premises where the landlord/ MCST (i.e. a mastermetered consumer or directly connected consumer) receives bulk intake service connection from SPPA, and transforms/ reticulates the supply to all the tenants (i.e. sub-metered consumers) within the premises. Any application for new or modified connection (includes upgrading) for the bulk intake to the multi-metered premises must be made by the landlord through its LEW. (b) 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. 8 (c) A master-metered installation means an installation in which supply is received by a master-metered consumer and sub-metered consumers (d) A master-metered installation shall have an independent address and its own dedicated access. (e) 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. 2.6.2 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. 2.6.3 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 existing premises. In this case, the existing service cables are amalgamated with the new intake. Hence, there will not be separate direct connections to the tenants of such premises. 2.7 Premises in Private Housing, Industrial Estates, Commercial Developments Requiring Provision of Low Tension (LT) Distribution Network 2.7.1 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. 2.7.2 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. 2.7.3 In the case of landed housing estate development, the LEW must liaise with relevant Authorities, applicant’s appointed Architects/Civil & Structural Qualified Person and owner of the house for the siting of proposed overground distribution boxes on turfed areas. SPPA will provide and install the LT distribution network and service connection cables for the development. 2.7.4 Premises Involving Temporary Connection with Provision of Substation: (a) 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. (b) 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 SPPA. 9 (c) 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 during the term for temporary connection. 2.7.5 Developers are advised to connect residential developments to the LT distribution network. Opting for a HT supply intake setup will subject the landlord/MCST to the following: (a) Monthly Contracted Capacity charges (b) Operating costs associated with HT equipment setup 2.8 Provision of Substation 2.8.1 When an application for load connection necessitates the provision of a substation (Appendices 9 and 10), a site must be provided and a substation constructed by the customer at its own cost. 2.8.2 The customer can either choose his substation to be a dedicated or non-dedicated one (Appendix 35). If the customer opts for a dedicated substation, he has to inform SPPG when he applies for connection. Otherwise, it shall be assumed that the substation would be non-dedicated. 2.8.3 The substation is to be sited at an inconspicuous location, away from the main entrance of the development and major public roads. It is recommended to harmonise, blend and integrate the substation with the overall design of its development. The siting of the substation must ensure continuous and unobstructed vehicular access to the substation and the associated lead-in pipes at all times, to facilitate equipment delivery, operational activities, maintenance and cabling works by SPPG. 2.8.4 SPPG’s officers and vehicles will have full and unrestricted access to the substation at all times (Appendix 15). 2.9 Service Connection Cables 2.9.1 Generally, SPPA supply, install and maintain customer service cable. However, if the customer’s switchroom is not abutting to SPPA’s switchroom or at different level to the substation building, or service cable to be installed in cable tray/ ladder, or the cable termination to the customer switchboard is not via bottom entry, the customer shall supply, install and maintain the service cable. In the event that customer supplies the service cable, the customer’s LEW shall ensure that the service cable complied with SPPA cable specification, and submit cable sample and specification to Distribution Engineering Section for approval prior to procurement. The general type of cables for service connection is shown in Appendix 36. 2.9.2 For service cable that is supplied, installed and maintained by SPPA, customer shall provide UPVC lead-in pipes from intake point to 300mm beyond boundary line or the roadside drain abutting public road at a depth not exceeding 2.0m from the finished road level.

For service connection at 66kV or above, the lead-in pipes shall 10 be installed under drain / box culvert / utility service duct immediately outside site boundary and are to be extended up to 300mm beyond the road kerb where applicable. 2.9.3 Draw pit(s) shall be provided strategically including each turn of the service cable to facilitate the installation of the service cable. 2.9.4 The distance between surface of trench and service cable termination point shall be at least 900mm. 2.10 Opening of Account for Upgrading/ Downgrading of Electricity Supply (Assuming No Change in Contestability Status) 2.10.1 The consumer is not required to open a new account if the electricity supply remains at low voltage (LV) 2.10.2 The consumer is required to open a new account if the electricity supply is upgraded from LV to high voltage (HV), and the existing LV supply is cut off before the new HV supply is turned on. 2.10.3 The consumer is required to open a new account if the electricity supply is changed from LV to HV, HV to LV or HV to HV at different voltage level (e.g. 6.6kV to 22kV), when the new and existing supply intakes are to run concurrently during transition period. 2.11 Consultation for Transmission Connection 2.11.1 A customer may choose to seek preliminary comments from SPPG via the connection consultation process before submitting a formal application. This practice is encouraged as incorporating SPPA’s requirements in a developer’s preliminary proposal would expedite the application process at a later stage. 2.11.2 To initiate the connection consultation process, the customer has to submit the online Consultation Form through an LEW via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg. 2.12 Application for Transmission Connection 2.12.1 The following are steps in the application for service connection: (a) The customer submits the online Application Form 2 through an LEW via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg, together with a letter of consent (Appendix 1) and IMDA acknowledgement email (for data centre applications only). 2 The 5-year load projection provided by the Customer in the CS1 application form is for planning purpose. Securing of network capacity is achieved by confirmation of Contracted Capacity in Customer Connection Agreement or approval of Revision of Contracted Capacity by the Transmission Licensee. 11 (b) 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. SPPG endeavours to respond to the customer within 60 business days and 100 business days for 66kV connections and 230kV connections respectively. 2.12.2 Where the application requires the provision of an EHT substation, the customer must adhere to the general requirements (Appendix 16). 2.12.3 Once customer acknowledges acceptance of SPPG’s connection proposal, SPPG proceeds to execute the Consumer Connection 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. 2.13 Lead-Time for Application of Transmission Connection 2.13.1 The timely provision of electricity supply to a development involves the joint efforts of SPSL, SPPG, and the customer and their agents, such as the LEW. While SPSL and SPPG 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 SPPA or Transmission Code requirements. It is the responsibility of the customers to manage and direct their agents to ensure that their agents comply with the necessary SPPA or Transmission Code requirements. 2.13.2 As a guide for the customer and their agents, the typical lead-times for the events leading to the energisation of 66kV service connections, for a service cable length of approximately 2km, are listed in the box below. The actual lead time for 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. 2.13.3 Estimated Lead Time for Energisation of 66kV Service Connection Events New 66kV connection from SPPA’s nearest existing substation From day of execution of consumer connection agreement to energisation of service connection 26 Months 1 Notes: 1 Lead time is based on a service cable length of approximately 2km and is subject to change based on length of service connection cables. Note that this lead time excludes additional time required to comply with requirement from URA Infrastructure Planning Authority Group (IPAG). The customer needs to consult SPPG at least 5-8 years in advance to cater for advanced planning. 12 2.14 Technical Requirements of Distributed Generation and New Extra / Ultra High Tension Connection 2.14.1 The details of technical requirements at the electricity supply network Point of Common Coupling (PCC) for Distributed Generation (DG) and New Extra / Ultra High Tension (EHT/UHT) connection are highlighted in Appendix 46. 2.14.2 The Consumer shall ensure that multiple sources of transmission, and/or distribution, systems are not connected in parallel at any time, and that any switching between circuits is undertaken on “black changeover” or “break before make” basis. 2.14.3 Some of the requirements are covered in the Transmission Code issued by Energy Market Authority (EMA).

SPPG will determine the location where the supply line terminates in the premises, based on ease of accessibility to SPSL and SPPG personnel. 6.1.2 “Electricity Meter” means the electrical device capable of measuring the flow electrical power. 6.1.3 “Meter Installation” means the associated ancillaries (excluding the meter) that includes, but not limited to, the meter board, self-contained metering transformers, wiring, test links, incoming miniature circuit breakers, outgoing isolator etc. 6.1.4 The electricity meters are owned, supplied and maintained by SPPG acting as an agent of SPPA. 6.1.5 The meter installation (excluding the electricity meter) ie. the meter boards, incoming miniature circuit breakers (MCBs), outgoing isolators, electrical wiring and all other electrical or mechanical ancillaries that makes up the meter installation are owned, supplied and maintained by the “Owner” - developer of the estate / estate manager / MCST / HDB upgrading contractors / Town Councils or customer etc. 6.1.6 The Incoming and Outgoing MCBs of the meter are to be clearly labelled accordingly with “Incoming” and “Outgoing” for clear indication and operation. 6.1.7 The “Owner” and its appointed representative for the entire electrical licenced installation which the meter installation is part of, is solely responsible for the maintenance eg. checking and tightening of connections of the meter installation and its ancillaries including that at the meter terminals where the electrical wires belonging to the “Owner” terminate as part of its licensee obligation. “Owners” are allowed to break the SPPA seals and carry out the works by informing Electrical Meters Section so that it can be re-sealed post maintenance. 6.1.8 For “Owners” who install meter box over the meter installation, it is mandatory to submit to Electrical Meters Section the product datasheet for the meter box indicating the IP ratings that ensure the UV-resistance and weather-hardiness of the meter box to withstand the local weather conditions in Singapore. For meter box found at legacy HDB blocks, “Owners” are to provide the meter box datasheet from HDB as per their design specifications. This would apply for upgrading or re-wiring that will affect position / wiring of the electricity meter. It is not required to provide a meter box if the meter installation is located within an enclosure (meter compartments / risers / ducts etc) that shields the meter installation from the elements. “Owners” should take the chance to remove the meter box from such locations wherever practically reasonable if such had meter box installed historically. 34 6.1.9 Electrical Meters Section reserves the rights to decline any express service meter installation request submitted less than 4 business days before the scheduled date of electrical turn-on, due to the lead time required for schedule and resource availability allocation. Applicants are to note that express service charges do not supersede the 4 business days lead time due to
