An app to keep tabs on energy, water usage Test project between PUB, EMA and SP Services to help cut carbon footprint By CAROLYN KHEW A MOBILE app launched yesterday can be used to keep tabs on home energy and water consumption. About 310,000 residents will be the first to try out the app, which lets them check their estimated utility usage and find out which appliances are consuming the most energy and water. It also offers energy- and water-saving tips. Users may set a savings target for future bills, look at their utility consumption over the past six months and compare this with their neighbours’. They can view their bill and payment history, and update their mailing addresses. The test – from now to April – is a joint pilot project between SP Services, a subsidiary of Singapore Power (SP), the Energy Market Authority (EMA) and national water agency PUB. SP Services said it will look at the results from the pilot before extending the app to all users with an online SP utility account. For the pilot, only residents who have registered for such an account as of Sept 15 last year are eligible. The SP website shows the average electricity use for last October ranged from 131 kilowatt hour About 310,000 HDB residents will be the first to try out a new mobile app which will, among other things, let them check their estimated utility usage and find out which appliances are consuming the most energy and water.

The average utility bill for households with gas went from about $70 for a one-room flat to about $180 for a five-room flat. “Saving energy is a good way to help ensure a sustainable future. The new app will enable home- owners to analyse their use of electricity and gas,” said Mr Yeo Yek Seng, acting chief executive of EMA. “It will empower them to make an informed decision on efficient use of energy, lower their utility bills and reduce their carbon footprint.” The app is available for download from the iTunes or Google Play Store. Those with questions about the pilot project can e-mail csonline@singaporepower.com.sg or call the SP Services’ hotline on 1800-738-2000.

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.
