SP Energy HubAnnual ReportReliabilitySustainabilityInnovation All charged up for a career in engineering RELIABILITY When Executive Engineer Lim Kai Herng took up SP’s Mid-Term scholarship 5 years ago, he was motivated by a huge sense of pride, knowing that his work will help ensure reliable power supply to all residents and businesses in Singapore. The 27-year-old now leads a team of technical officers and technicians to maintain and renew high-voltage equipment and power cables. We caught up with Kai Herng to learn about his role, responsibilities, and motivations at SP. Tell us more about your current role. As a Distribution Network engineer, my work entails equipment maintenance and renewal. We are also the first responders on the ground when there is a power disruption. Executive Engineer Lim Kai Herng guides his colleague, Engineer Lim En Ping, as they carry out switching work at a substation. What is your most memorable achievement to date? When I first started as an engineer, my team and I were tasked to upgrade the existing 6.6kV network equipment at the western part of Singapore. Some of them are at least 20 to 30 years old and did not have in-built remote control and monitoring functions. With advancements in technology, we are now able to retrofit existing equipment to “send” information to our control centre. With the upgrade, power supply can be restored more quickly in the event of disruption. The team successfully completed this project in early 2020 – it is a milestone that I am very proud of! What are some of your biggest challenges at SP and how did you overcome them? As electricity and gas networks are critical infrastructure, close customer engagement for timely equipment and network maintenance becomes even more important. One of the key challenges is the rounds of discussions and negotiations with customers to schedule electricity supply shutdowns, for maintenance works to take place. In order to minimise disruption and inconvenience to customers we need to offer flexible solutions such as staggering shutdown times or providing alternate electricity supply during maintenance work.  Kai Herng cited the importance of strong camaraderie and teamwork. “It is no doubt a  heavy responsibility, but our unwavering focus on keeping Singapore lit keeps us going!”   This article was first published in BrightSparks Magazine February 2021.

GAS TRANSPORTATION TARIFFS (for Shippers with Natural Gas Distribution customers) (W.E.F. 1 Apr 24) 1 Introduction 1.1 Under the Gas Network Code, PowerGas is the Gas Transporter and is responsible for maintaining the reliability and safety of the gas transportation network in Singapore. PowerGas’ transportation business is regulated by the Energy Market Authority (EMA). The transportation tariffs levied by PowerGas are approved by the EMA. 1.2 The transportation tariffs are levied on Shippers. Shippers pay transmission as well as distribution charges as part of the distribution tariff for transportation of natural gas to distribution-level end-users. This is to reflect the cost of transporting gas through both the transmission and distribution networks. 1.3 End-user transportation charges imposed by Shippers are commercial arrangements between the Shippers and their end-users. 2 Natural Gas Distribution Tariffs 2.1 Arising from EMA’s notification to the industry dated 21 March 2024, a GSC of 20 cents/mmBtu for PNG Injection Points or GSC of 2 cents/mmBtu for LNG Injection Points is imposed on PNG and LNG gas users respectively with effect from 1 Apr 24 to recover the cost associated with Strategic Capacity (as defined in EMA's Policy Paper issued to the industry dated 30 Sep 2019). The Transporter will collect the GSC from all Shippers as an agent for and on behalf of SLNG. The GSC will be reviewed from time to time as directed by EMA and will be included as an uplift in the transmission usage charge. 2.2 The Distribution tariff is made up of two components (i.e. a Transmission Charge component and a Distribution Charge component). 3 Transmission Charging Structure 3.1 Transmission charges consist of capacity and usage charges. Shippers book capacity with PowerGas to transport gas from designated injection points to off-take points. Shippers pay entry and exit charges based on their respective booked capacity. In addition, uniform usage charge is levied on the volume of gas transported. Details of the transmission charge components are shown in Table 1 of the Appendix. 3.2 Shippers will have to pay Overrun Charges in the event they off-take gas above their booked capacity. These Overrun Charges are necessary to encourage the efficient use of the gas network. There are two types of Overrun Charges: • Authorised Capacity Overrun Charge: If a Shipper applies for additional capacity above the booked capacity (i.e. capacity overrun), the Authorised Capacity Overrun Charge, equivalent to 1.25 times the Transmission Capacity Charge rate, shall be applied on that additional capacity. • Unauthorised Capacity Overrun Charge: If a Shipper does not apply for Authorised Capacity Overrun for utilisation of additional capacity above the booked capacity, it will pay 2 times the Transmission Capacity Charge rate for that additional capacity utilised. 4 Distribution Charging Structure The Distribution Charge component is a usage-based charge in $/MMBtu. The Distribution Network is segregated into two service areas as follows: • The Jurong Island, Jurong and Tuas (“JIT”) area 2 • Outside the JIT area As the cost to serve the area outside JIT is higher than the JIT area, this results in a higher usage charge for the former. The Distribution Charges are shown in Table 2 of the Appendix. 5 Appendix – Table of Charges Table 1: Transmission Charges for Shippers with Natural Gas Distribution Customers (Exclusive of GST) Entry capacity charge ($/MMBtu/hr) Per Annum (a) Exit capacity charge ($/MMBtu/hr) Per Annum (b) Transmission capacity charge ($/MMBtu/hr) Per Annum (a) + (b) Transmission usage charge (comprising non-GSC and GSC) (¢/MMBtu) a) PNG source Transmission Network 1 970.19 1,718.49 2,688.68 1.40 + 20.0 Transmission Network 2 * 1,616.07 1,072.62 2,688.69 1.40 + 20.0 Transmission Network 2^ 1,240.93 1,447.75 2,688.68 1.40 + 20.0 b) LNG source Transmission Network 1 1,165.26 2,017.34 3,182.60 1.71 + 2.00 Transmission Network 2 1,185.71 1,996.89 3,182.60 1.71 + 2.00 Table 1a: Transmission Charges for Shippers with Natural Gas Distribution Customers (Inclusive of 9% GST) + Entry capacity charge ($/MMBtu/hr) Per Annum (a) Exit capacity charge ($/MMBtu/hr) Per Annum (b) Transmission capacity charge ($/MMBtu/hr) Per Annum (a) + (b) Transmission usage charge (comprising non-GSC and GSC) (¢/MMBtu) a) PNG source Transmission Network 1 1,057.51 1,873.15 2,930.66 1.53 + 21.8 Transmission Network 2 * 1,761.52 1,169.16 2,930.67 1.53 + 21.8 Transmission Network 2^ 1,352.61 1,578.05 2,930.66 1.53 + 21.8 b) LNG source Transmission Network 1 1,270.13 2,198.90 3,469.03 1.86 + 2.18 Transmission Network 2 1,292.42 2,176.61 3,469.03 1.86 + 2.18 Notes: 1) Transmission Network 1 refers to the natural gas transmission network conveying both piped natural gas and regasified LNG from West Natuna (Indonesia) and the LNG Terminal.

30 Sep 2015 For Immediate Release MEDIA RELEASE ELECTRICITY TARIFF REVISION FOR THE PERIOD 1 OCTOBER TO 31 DECEMBER 2015 1. For the period from 1 Oct to 31 Dec 2015, electricity tariffs will decrease by an average of 9.3% or 2.06 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 18.4% compared to 3Q 2015. 2. The electricity tariff for households will be revised to 20.35 cents per kWh for 4Q 2015. The average monthly electricity bill for families living in four-room HDB flats will decrease by $8.78. 3. 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 Services Limited 10 Pasir Panjang Road #03-01 Mapletree Business City Singapore 117438 Co.
