Contractor Performance Management System Introduction 1. With effect from 1 October 2016, Singapore Power Limited and its Singaporeincorporated subsidiaries (SP Group) has implemented the SP Group’s Contractor Performance Management System (CPMS) to strengthen its partnership with and improve the safety and quality performance of its contractors. 2. Through the CPMS, SP Group aims to take a holistic approach to the selection of its contractors as part of enhancing procurement process, by looking at the performance of its contractors at a quarterly and annual basis and not only based at performance at each individual contract basis. The previous demerit scheme in respect of each contract will be abolished while an incentive and mitigation scheme that goes towards enabling contractors to improve their performance on a longer term basis is now implemented. Objectives 3. The objectives of the CPMS are: (a) (b) (c) to adopt a more holistic approach in reviewing contractors’ overall performance; to work with contractors to raise safety and quality standards; and to encourage an environment of continuous improvement by contractors. 4. In order to achieve the above objectives, CPMS will utilise the following 3 main components: (a) (b) (c) Contractor Performance Assessment (CPA); Business Under Surveillance (BUS) Programme; and Tender Evaluation Framework (TEF). SP Group CPMS V6.0 19 Jul 2023 1 Applicability 5. The CPMS will be applicable for procurement in relation of the following services and works: (a) (b) (c) (d) (e) (f) cable installation, cable jointing and road reinstatement; gas pipe-laying; milling and patching; transmission cable-laying; building and construction; and other road opening-related works (e.g., manhole access works). SP Group intends to broaden the scope of the CPMS to eventually apply the CPMS for procurement of other engineering-related works and services. 6. The CPMS will apply to contracts awarded on or after 1 October 2016 and any ongoing contracts which fall in any of the above categories set out in paragraph 5. All aspects of the CPMS, such as the BUS Programme and rewards and mitigations, will apply to such contracts. Contractor Performance Assessment 7. For each contract, a contractor will be assessed by the relevant SP Group project team in the following four (4) areas: (a) (b) (c) (d) Safety. Quality of Work; Project & Risk Management; and Value Added Services. These scores for each contract (Contract Quarterly Score) will be tabulated at fixed quarterly basis. The individual Contract Quarterly Scores applicable for each contract will then be averaged to derive the Contractor Quarterly Score. SP Group CPMS V6.0 19 Jul 2023 2 The criteria have a direct impact on risk mitigation which helps to review the way work activities are planned and executed. The objective of the enhancements is to reduce risk and improve safety at work sites. The PSR shall review the risk identification and mitigation measures to be taken during the design & construction for all contracts within SP Group. Emphasis will be given to the PSR communication to workers through the Risk Management workshops on site. ABSIS will be used to engage with the worker level to improve work processes and create a safer environment to work in. SP Group will assess the contractors’ senior management engagement with their workers through various in-house activities. 8. Examples of the factors taken into consideration in determining the individual Contract Quarterly Score are as follows Safety • Safety Performance • Site Safety Management • Safety Engagement by Management • Project Safety Review (PSR) • Risk Management workshop • Activity Based Safety Improvement System (ABSIS) Quality of Work • Documentation • Workmanship • Any damage to properties Project & Risk Management • Incident management • Cooperativeness • Meeting schedules Value Added Services • Initiatives to improve productivity and efficiency SP Group CPMS V6.0 19 Jul 2023 3 9. In addition to the above criteria, SP Group will also take into account the occurrence of any Critical Incidents when determining the Contractor’s Quarterly Score by applying a corresponding adjustment factor to their score. (a) The Critical Incidents includes: Critical Incidents Smoking or open flame in gas installations and electricity transmission substations Not adhering strictly to isolation procedures for live electricity or gas equipment and machinery at site Damage to Transmission Cables / Gas Pipes Damage to Distribution Cables / Gas Pipes Not anchoring safety harness while working at heights exceeding 3 metres Working in a confined space without conducting mandatory gas check Working under suspended load during lifting or excavator operations Fatality or serious injury Where Serious Injury is defined as: Serious Injuries Loss of 2 limbs Loss of both hands or of all fingers and both thumbs Loss of both feet Total loss of sight, including the loss of sight to such extent as to render the employee unable to perform any work for which eyesight is essential Total paralysis Injuries requiring more than 20 days of hospitalization. (Hospitalization refers to the period where injured remains warded in a hospital) Loss of arm at shoulder Loss of arm between elbow and shoulder Injuries resulting in being permanently bedridden Loss of arm at elbow Loss of arm between wrist and elbow SP Group CPMS V6.0 19 Jul 2023 4 Loss of hand at wrist Loss of 4 fingers and thumb of one hand Loss of 4 fingers Loss of leg • At or above knee • Below knee Loss of foot Loss of sight of one eye Total loss of hearing (b) The Serious Incidents includes: Serious Incidents Damage to Distribution Cables/ Gas pipes affecting less than or equal to 300 customers Damage to Public assets (e.g., PUB pipes, streetlights) Note: Contractors shall not be penalised for damages to the public assets if it was unavoidable due to Authorities’ drawings that provided inaccurate factual information and the Contractor’s detection works did not provide better information. 10. At the end of each quarter, SP Group will provide each contractor a grade relative to their score to provide them timely information on their performance. The names and grades for each contractor scored in each quarter shall be available on the SP Group corporate website. 11. In the event the Contractor’s Quarterly Score is lower than 50, the contractor will be suspended from participating in any new procurement activities for the next 3 months. In the event of an occurrence of a fatality or serious injury at his work site, the main contractor and its subcontractor will be suspended from participating in any new procurement activities for 12 months from the incident date. The suspended contractors and their subsidiaries are also not allowed to apply to be sub-contractors for any SP Group contracts during the suspension period. SP Group CPMS V6.0 19 Jul 2023 5 12. The Contractor Quarterly Scores will be aggregated on an annual basis [Contractor Annual Score]. Contractors must have at least two (2) Contractor Quarterly Scores to be included for the Contractor Annual Score computation. 13. At the end of each Assessment Year, the 5 contractors with the highest Contractor Annual Score for the year will be given an incentive of 2% of the total annual value of their respective contracts capped at $100,000.00 per year per contractor. The annual value of each contract is computed as follows: where: ACV is the annual value of a contract; ACV = A X B A is the Contract Sum divided by the Contract Period [weeks]; and B is the number of weeks [or part thereof] where Works carried out in that year under that contract. 14. The 2 contractors with the lowest annual scores will be subjected to a penalty deduction to their PQS scores in all subsequent SP Group tenders published during the next Assessment Year. In addition, they would also have to comply with performance improvement requirements specified by SP Group to address areas of deficiency. SP Group CPMS V6.0 19 Jul 2023 6 Business Under Surveillance (BUS) Programme 15. The BUS Programme is an educational and correctional tool aimed to partner contractors to address safety and quality issues encountered by contractors in the course of their work for the SP Group and in the longer term help improve their safety and quality standards. The BUS Programme and will be activated in the following situations: (a) (b) Occurrence of any Critical Incident; and/or 3 or more safety inspections at the project sites where major safety-related non-conformances (safety non-conformance) are observed. 16. In the event of the activation of the BUS Programme, the Contractor will be required to undergo the activities as follows: 17. Stopping work at the affected site[s] during a BUS Programme is important to allow contractors to review its safety practices and focus on its operational methods and processes with the aim of preventing further incidents from occurring again. 18. If the contractor placed on a BUS Programme is unable to meet the exit requirements at the end of the 5 th week, a further 2 weeks extension will be granted. If the contractor is still unable to meet the exit requirements at the end of the 7 th week, the contractor will be placed on a second BUS Programme to address the failure of the first BUS Programme. SP Group CPMS V6.0 19 Jul 2023 7 19. In the event the contractor is placed on the BUS Programme more than 2 times in a calendar quarter, the contractor will be suspended from participating in any new procurement activities for the next three months. The suspended contractors and their subsidiaries are also not allowed to apply to be sub-contractors for any SP Group contracts during the suspension period. 20. From 1 Apr 2023, Contractor shall not be under MOM’s Business Under Surveillance programme (BUS) OR not accumulated 25 or more demerit points under MOM’s DPS as at the Tender Closing Date and before the Tender Award Date. Tender Evaluation Framework 21. The CPMS adopts a tender evaluation framework that comprises the following 3 Stages: 22. Stage 1 (SET) aims to inculcate a mindset of safety being the highest priority among our contractors, by selecting only likeminded contractors who have adequate safety management system and track records to work on our projects. Contractors who meet the SET requirements will be pre-qualified to participate in SP Group’s tenders for works described in paragraph 5 above. Once such pre-qualification is granted by SP to the contractors, it shall be valid for the entire Assessment Year. Any contractor which fails the Stage 1 assessment can apply for re-assessment at the start of new calendar quarter after being notified of its failure to pre-qualify. SP Group CPMS V6.0 19 Jul 2023 8 23. In the subsequent Stage 2 and 3 of the evaluation of bids submitted for CPMS applicable tenders, each bidder’s Contractor Quarterly scores over the past 2 years will be taken into account to determine the successful bidder. Where a bidder does not have sufficient records of past Contractor Quarterly Scores (e.g. new contractors) a default score will be used instead. Amendments and FAQs 24. SP Group may modify the CPMS at any time and such amendments shall be deemed immediately applicable to the contracts that are ongoing at the time of such amendments. Contractors are strongly encouraged to check https://www.spgroup.com.sg/doing-business-with-us/procurement for amendments, updates and FAQs relating to the CPMS. 25.

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. Online information on the latest electricity tariffs is available at www.spgroup.com.sg. 1.8 Payments for Electricity Charges by Contestable Customers 1.8.1 Contestable customer pays 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 1.9.1 The customer must open an account and place a security deposit for UOS charges with SPSL upon application for energisation of service connection. 4 1.10 Termination of Account 1.10.1 Non-contestable customers must give 4 business days' notice and contestable customers must give 7 business days’ notice to terminate an account. Termination can be submitted to SPSL via the digital channels available, unless the contestable customer is under an electricity retailer which in this case termination should be submitted to the electricity retailer. The customer must also request for removal of service cable (if necessary) upon notice to terminate the account. Upon receipt of a completed form, electricity supply will be terminated on the 8th business day for contestable customers. For High-Tension (HT) consumers, LEW is required to be present and to ensure the premise is ready for cut-off on the appointment date. 1.11 Disconnection of Service Cables upon Termination of Account 1.11.1 Disconnection work involves the de-energisation of service cables. It may also involve the removal of service cables and/or equipment if they are no longer required. 1.11.2 Where the removal of service cables and/or equipment is involved, the following are indicative lead times for the work: (a) After the de-energisation of LT service cable, the lead-time is about 5 business days for the removal of LT service cables where road-opening work is not involved. (b) Where road opening work is involved, a lead-time of 2 months is required. (c) After the de-energisation of 6.6KV and 22KV service cables, the lead-time is about 3 months. (d) For disconnection of 66kV and 230kV service cables, the lead-time for the deenergisation of service cables/ equipment is about 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. 1.11.3 Customers should take note the disconnection of service cables and termination of account are separate process. The respective lead time required must be catered for by the customer to the respective SP entities. 1.12 General 1.12.1 The customer agrees to comply with the terms of this document and to procure that its officers, agents and representatives shall so comply. 1.12.2 None of SPSL, SPPA, SPPG, Singapore Power Limited or any of Singapore Power Limited's affiliates (a "SP Entity") will be liable (including without limitation, for negligence or any other category of liability whatsoever) for any action taken by any of them under or in connection with the matters arising under or out of this document. No customer or any of a customer's officers, employees, agents or other representatives may take any proceedings against any officer, employee or agent of any SP Entity in respect of any act or omission of any kind by that officer, employee or agent in relation to any matter arising under or out of this document. 5 1.12.3 Each of SPSL, SPPA and SPPG retains the right, at its sole and absolute discretion, to amend, vary and/or supplement any terms of this document from time to time and its interpretation of any terms of this document shall be final and binding. 1.12.4 No failure on the part of each of SPSL, SPPA and SPPG to exercise, and no delay on its part in exercising, any right or remedy under this document will operate as a waiver thereof, nor will any single or partial exercise of any right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies provided to SPSL, SPPA and SPPG in this document are cumulative and not exclusive of any other rights or remedies (whether provided by law or otherwise). 1.12.5 Nothing in this document shall in any way affect the obligations of a customer and its officers, employees, agents or other representatives to comply with applicable provision of the Electricity Act and all regulations and codes promulgated thereunder. 6 2. Application For Load Connection 2 Application for Load Connection 2.1 Load Connection 2.1.1 Each premise, as identified by the house or block number issued by IRAS, is limited to a single customer intake connection point. For modification of connection (such as upgrading of the load requirement) to existing premises, the customer is required to amalgamate all existing service connection into one intake. 2.2 Consultation 2.2.1 For developments in the initial planning stage, the customer is advised to seek consultation with SPPG to ascertain SPPA‘s requirements for a new or modified connection to the transmission system. This includes considerations such as the provision of a substation, modifications to an existing 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 LEW is required to submit the online Consultation Form via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg, together with a site/location plan to SPPG. 2.2.2 After receipt of the submission for consultation, SPPG 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. 2.3 Application 2.3.1 The online Application Form 1 together with a letter of consent (Appendix 1) and a copy of the site/ location plan must be submitted via Singapore Power (SP) eBusiness Portal at www.spgroup.com.sg by the LEW for new or modified connections of new or existing premises to the transmission system. 1 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. 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.

Media Release Electricity Tariff Revision For The Period 1 April To 31 June 2016 For the period from 1 Apr to 30 Jun 2016, electricity tariffs will decrease by an average of 9.6% or 1.83 cents per kWh compared to the previous quarter. The tariff reduction is due to the lower cost of natural gas for electricity generation which fell by 20.2% compared to 1Q 2016. While network costs went up due to infrastructure investment to replace ageing assets and meet rising electricity demand, the lower cost of natural gas more than offset this increase. For households, the electricity tariff will decrease from 19.50 to 17.68 cents per kWh for 1 Apr to 30 Jun 2016. The average monthly electricity bill for families living in four-room HDB flats will decrease by $6.71 (see Appendix 3 for the average monthly electricity bill for different household types). SP Services reviews the electricity tariffs quarterly based on guidelines set by the Energy Market Authority (EMA), the electricity industry regulator. The tariffs given in Appendix 1 have been approved by the EMA. Issued by: SP Group 2 Kallang Sector Singapore 349277 www.spgroup.com.sg Appendix 1 ELECTRICITY TARIFFS FROM 1 APR 2016 Appendix 2 BREAKDOWN OF ELECTRICITY TARIFF 1. The electricity tariff consists of the following four components: Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of power generation. Network costs (paid to SP PowerAssets): This fee is reviewed annually. Market Support Services Fee (paid to SP Services): This fee is reviewed annually. Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.

Contractor Performance Management System Introduction 1. With effect from 1 October 2016, Singapore Power Limited and its Singaporeincorporated subsidiaries (SP Group) has implemented the SP Group’s Contractor Performance Management System (CPMS) to strengthen its partnership with and improve the safety and quality performance of its contractors. 2. Through the CPMS, SP Group aims to take a holistic approach to the selection of its contractors as part of enhancing procurement process, by looking at the performance of its contractors at a quarterly and annual basis and not only based at performance at each individual contract basis. The previous demerit scheme in respect of each contract will be abolished while an incentive and mitigation scheme that goes towards enabling contractors to improve their performance on a longer term basis is now implemented. Objectives 3. The objectives of the CPMS are: (a) (b) (c) to adopt a more holistic approach in reviewing contractors’ overall performance; to work with contractors to raise safety and quality standards; and to encourage an environment of continuous improvement by contractors. 4. In order to achieve the above objectives, CPMS will utilise the following 3 main components: (a) (b) (c) Contractor Performance Assessment (CPA); Business Under Surveillance (BUS) Programme; and Tender Evaluation Framework (TEF). SP Group CPMS V7.0 12 May 2025 1 Applicability 5. The CPMS will be applicable for procurement in relation of the following services and works: (a) (b) (c) (d) (e) (f) cable installation, cable jointing and road reinstatement; gas pipe-laying; milling and patching; transmission cable-laying; building and construction; and other road opening-related works (e.g., manhole access works). SP Group intends to broaden the scope of the CPMS to eventually apply the CPMS for procurement of other engineering-related works and services. 6. The CPMS will apply to contracts awarded on or after 1 October 2016 and any ongoing contracts which fall in any of the above categories set out in paragraph 5. All aspects of the CPMS, such as the BUS Programme and rewards and mitigations, will apply to such contracts. Contractor Performance Assessment 7. For each contract, a contractor will be assessed by the relevant SP Group project team in the following four (4) areas: (a) (b) (c) (d) Safety. Quality of Work; Project & Risk Management; and Value Added Services. These scores for each contract (Contract Quarterly Score) will be tabulated at fixed quarterly basis. The individual Contract Quarterly Scores applicable for each contract will then be averaged to derive the Contractor Quarterly Score. SP Group CPMS V7.0 12 May 2025 2 The criteria have a direct impact on risk mitigation which helps to review the way work activities are planned and executed. The objective of the enhancements is to reduce risk and improve safety at work sites. The PSR shall review the risk identification and mitigation measures to be taken during the design & construction for all contracts within SP Group. Emphasis will be given to the PSR communication to workers through the Risk Management workshops on site. ABSIS will be used to engage with the worker level to improve work processes and create a safer environment to work in. SP Group will assess the contractors’ senior management engagement with their workers through various in-house activities. 8. Examples of the factors taken into consideration in determining the individual Contract Quarterly Score are as follows Safety • Safety Performance • Site Safety Management • Safety Engagement by Management • Project Safety Review (PSR) • Risk Management workshop • Activity Based Safety Improvement System (ABSIS) Quality of Work • Documentation • Workmanship • Any damage to properties Project & Risk Management • Incident management • Cooperativeness • Meeting schedules Value Added Services • Initiatives to improve productivity and efficiency SP Group CPMS V7.0 12 May 2025 3 9. In addition to the above criteria, SP Group will also take into account the occurrence of any Critical Incidents when determining the Contractor’s Quarterly Score by applying a corresponding adjustment factor to their score. (a) The Critical Incidents includes: Critical Incidents Smoking or open flame in gas installations and electricity transmission substations Not adhering strictly to isolation procedures for live electricity or gas equipment and machinery at site Damage to Transmission Cables / Gas Pipes Damage to Distribution Cables / Gas Pipes Not anchoring safety harness while working at heights exceeding 3 metres Working in a confined space without conducting mandatory gas check Working under suspended load during lifting or excavator operations Fatality or serious injury Where Serious Injury is defined as: Serious Injuries Loss of 2 limbs Loss of both hands or of all fingers and both thumbs Loss of both feet Total loss of sight, including the loss of sight to such extent as to render the employee unable to perform any work for which eyesight is essential Total paralysis Loss of arm at shoulder Loss of arm between elbow and shoulder Injuries resulting in being permanently bedridden Loss of arm at elbow Loss of arm between wrist and elbow Loss of hand at wrist SP Group CPMS V7.0 12 May 2025 4 Loss of 4 fingers and thumb of one hand Loss of 4 fingers Loss of leg • At or above knee • Below knee Loss of foot Loss of sight of one eye Total loss of hearing (b) The Serious Incidents includes: Serious Incidents Damage to Distribution Cables/ Gas pipes affecting less than or equal to 300 customers Damage to Public assets (e.g., PUB pipes, streetlights) Note: Contractors shall not be penalised for damages to the public assets if it was unavoidable due to Authorities’ drawings that provided inaccurate factual information and the Contractor’s detection works did not provide better information. 10. At the end of each quarter, SP Group will provide each contractor a grade relative to their score to provide them timely information on their performance. The names and grades for each contractor scored in each quarter shall be available on the SP Group corporate website. 11. In the event the Contractor’s Quarterly Score is lower than 50, the contractor will be suspended from participating in any new procurement activities for the next 3 months. In the event of an occurrence of a fatality or serious injury at his work site, the main contractor and its subcontractor will be suspended from participating in any new procurement activities for 12 months (fatality) and 3 months (serious injury) respectively from the incident date. The suspended contractors and their subsidiaries are also not allowed to apply to be sub-contractors for any SP Group contracts during the suspension period. SP Group CPMS V7.0 12 May 2025 5 12. The Contractor Quarterly Scores will be aggregated on an annual basis [Contractor Annual Score]. Contractors must have at least two (2) Contractor Quarterly Scores to be included for the Contractor Annual Score computation. 13. At the end of each Assessment Year, the 5 contractors with the highest Contractor Annual Score for the year will be given an incentive of 2% of the total annual value of their respective contracts capped at $100,000.00 per year per contractor. The annual value of each contract is computed as follows: where: ACV is the annual value of a contract; ACV = A X B A is the Contract Sum divided by the Contract Period [weeks]; and B is the number of weeks [or part thereof] where Works carried out in that year under that contract. 14. The 2 contractors with the lowest annual scores will be subjected to a penalty deduction to their PQS scores in all subsequent SP Group tenders published during the next Assessment Year. In addition, they would also have to comply with performance improvement requirements specified by SP Group to address areas of deficiency.

Stage 1 (SET) aims to inculcate a mindset of safety being the highest priority among our contractors, by selecting only likeminded contractors who have adequate safety management system and track records to work on our projects. Contractors who meet the SET requirements will be pre-qualified to participate in SP Group’s tenders for works described in paragraph 5 above. Once such pre-qualification is granted by SP to the contractors, it shall be valid for the entire Assessment Year. Any contractor which fails the Stage 1 assessment can apply for re-assessment at the start of new calendar quarter after being notified of its failure to pre-qualify.
