The electricity tariff consists of the following four components: a) Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. b) Network costs (paid to SP PowerAssets): This fee is reviewed annually. This is to recover the cost of transporting electricity through the power grid. c) Market Support Services Fee (paid to SP Services): This fee is reviewed annually. This is to recover the costs of billing and meter reading, data management, retail market systems as well as for market development initiatives. d) 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.

Registration No.: [●] Your Ref: [●] Our Ref: [●] Dear Sir REQUIREMENTS FOR EARTHWORKS [●insert location●] (Site Meeting Date: [●]) 1. We refer to your Notice for Commencement of Earthworks (“NCE”) at the above-mentioned location ("Worksite") dated [●] and note that you will commence earthworks (as defined in Section 2 of the Electricity Act (Cap. 89A) (the "Act")) ("Earthworks") from [●] to [●]. 2. Pursuant to Section 80(4)(a) of the Act, you are required to comply with the following requirements when carrying out the Earthworks: 2.1. Establishing Electricity Cable Positions and Electricity Cable Routes 2.1.1. You shall engage a Licensed Cable Detection Worker (“LCDW”) to create an electricity cable (as defined in Section2 of the Act) ("Electricity Cable") corridor using adequate and prominent barricades and signposts. You shall strictly monitor and control, by using a Permit-to-Work (“PTW”) system, the Earthworks carried out inside the barricaded Electricity Cable corridor. 2.1.2. You shall ensure that the pegging and marking of Electricity Cable positions / routes are durable and prominent. You shall also ensure that such pegging and marking are not disturbed, removed or tampered with and are reapplied from time to time to ensure that they remain conspicuous for the entire project in which the Earthworks are or are to be carried out (“Project”). You shall not drive steel pins, spikes, long pegs or other similar objects into the ground as these can damage underground Electricity Cables. 2.1.3. You shall re-engage the LCDW to reconfirm the Electricity Cable positions before reapplying missing or faded pegs and surface markers on the ground or inside trenches. 2.1.4. You shall re-engage the LCDW to carry out Electricity Cable detection work and to update Electricity Cable detection drawing and peggings / markings at the Worksite after the carrying out of any Electricity Cable diversion, decommissioning of substation, new commissioning of substation and/or Electricity Cable termination work within the Worksite. You shall brief all Worksite personnel of the new positions of the Electricity Cable positions. Page 1 of 11 2.1.5. You shall ensure that the Electricity Cable peggings / markings are each installed at intervals no further than 3 metres apart. You shall indicate the voltage levels and the approximate depth of the Electricity Cable at such peggings / markings. 2.2. Risk Management 2.2.1. You shall assess the impact of carrying out the intended Earthworks on the Electricity Cables and Electricity Cable joints and prepare a report detailing such assessment. 2.2.2. If there are changes to the schedule for the carrying out of the Earthworks or changes in Earthworks work methods, you shall study the implications, review the earlier risk assessment that had been carried out and promptly notify SP PowerGrid Limited (an electricity licensee as defined in Section 2 of the Act) ("SPPG") in writing if there are any changes to such earlier assessment. 2.2.3. The report of such assessment shall be made available to SPPG on request. Such report shall also be made known to all personnel of all working levels in the Project team, including sub-contractors and any third party who are involved in any way with any part of the intended Earthworks. 2.3. Worksite Management 2.3.1. When working in the vicinity of an Electricity Cable, you shall carry out a site visit jointly with an Earthworks Surveillance & Patrolling section, SPPG (“ESP”) officer before carrying out any Earthworks specified under the submitted NCE. 2.3.2.

You shall keep records of such daily briefings (which shall include but are not limited to date and time, venue and person conducting the briefings, contents of briefings and the list of Worksite workers who have attended such briefings). You shall also disallow any Worksite worker who has not attended such briefings from being involved with any part of the intended Earthworks. New staff must be briefed before they start work. 2.3.4. You shall inform ESP officers of the identity of the Worksite management / LCDW / Registered Excavator Operator (“REO”), the proposed methods of carrying out of the Page 2 of 11 Earthworks and/or location of the proposed Earthworks. You shall also inform the ESP officers if there are any changes to the above. 2.3.5. You shall ensure that information on the presence of Electricity Cables in the vicinity of the Worksite and all mitigating measures to be taken to prevent damage to such Electricity Cables have been communicated and adhered to by all personnel of all working levels in the Project team, including sub-contractors and any third party who are in any way involved with any part of the intended Earthworks. 2.3.6. SPPG may, from time to time and at its sole discretion, deploy its officers to the worksite to inspect and monitor the status of your works. Notwithstanding the deployment of SPPG’s officers at the worksite, you shall continue to be responsible for discharging your obligations under this Letter of Requirements and for the performance of your works. SPPG shall not assume any liability for any noncompliance by you of any such obligation or non-performance of your works. 2.4. Trial Holes 2.4.1.

These requirements are applicable to all persons who carry out any Earthworks and strict compliance is required, unless otherwise permitted in writing by SPPG. Please consult the relevant SPPG section, if necessary. 3.2. The requirements stated above are not exhaustive. Additional requirements may be issued from time to time by SPPG. These additional requirements, together with the requirements in this letter, shall form the full list of requirements that must be complied with at all times. You are advised to carry out all necessary assessments and take all necessary precautions to prevent damage to any existing Electricity Cables. 3.3. Pursuant to Section 80(4)(a) of the Act, it shall be the duty of the person who carries out any Earthworks to comply with all reasonable requirements of SPPG for the prevention of damage to a high voltage Electricity Cables. Pursuant to Section 80(7) of the Act, any person who contravenes Sections 80(4)(a) of the Act shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $100,000 or to imprisonment for a term not exceeding 5 years or both. Further, Section 85(1) of the Act provides that any person who, removes, destroys or damages any Electricity Cable which is part of a transmission system that belongs to or that is under the management or control of SPPG, shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $1 million or to imprisonment for a term not exceeding 5 years or to both.

Media Release Electricity Tariff Revision for the Period 1 July to 30 September 2022 Singapore, 30 June 2022 – For the period from 1 July to 30 September 2022, electricity tariff (before 7% GST) will increase by an average of 8.1% or 2.21 cents per kWh compared with the previous quarter. The increase is mainly due to higher energy cost driven by rising global gas and oil prices exacerbated by the conflict in Ukraine. For details on the components of the electricity tariff, please refer to Appendix 1: Breakdown of Electricity Tariff.
