SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Pushing boundaries to impact future generations RELIABILITY Managing high voltage equipment is all in a day’s work for our senior engineer Tan Jie Yi. She works in the Transmission Operation and Maintenance team, part of the 24/7 operations that contribute to Singapore’s world-class network reliability. No detail is too small when conducting maintenance work for switchgears – key components in the smooth distribution of electricity to customers in industries, businesses and households. With 13 years of engineering experience under her belt, Jie Yi is unfazed by the technical and hands-on nature of her job. Join us as we discover how Jie Yi’s career has come “full circle” for her and has fuelled her passion in engineering. Tan Jie Yi, Senior Engineer in Transmission Operation and Maintenance team, finds joy and fulfilment in keeping the nation’s world-class electricity grid running. Finding her path into the engineering industry more than a decade ago, Jie Yi’s passion for scaling new heights led her to where she is today in SP Group. Formerly in the switchgear manufacturing industry, Jie Yi literally switched gears when she joined SP, as she deepened her technical expertise by learning to manage the full cycle of switchgears – from installation to maintenance. “Now that I’m on the client side, I can better appreciate the priorities and challenges faced during maintenance and understand how we can address them during the project installation phase. Like most engineers, I enjoy problem-solving. The adrenaline rush keeps me going!”   Here, we see Jie Yi assisting to perform switching work in a transmission substation. Electrical networks have to be shut down safely before maintenance work can be carried out. The team performs equipment maintenance and renewal according to a rigorous schedule. When asked about what it takes to prove her mettle in a field that has been conventionally male-dominated, Jie Yi’s advice is to strengthen one’s competency. “You need to put in effort to have sound knowledge of the operations and protocols. Gender doesn’t get in the way when you can stand up to the quality of your work.” Jie Yi is currently undergoing training to attain her switching certificate. This will allow her to operate high-voltage equipment independently. Jie Yi’s advice to those interested in engineering is to start from ground up to build a strong knowledge foundation, and always be hungry to know and learn more. “When you start from the bottom, there is nowhere to go but up,” she shares. This philosophy is mirrored in her own career, where she started as an engineering assistant and worked her way up to become a project manager. To Jie Yi and her team, they believe that the work they are doing today, is an investment for generations to come. This also holds true as she embarked on a new journey as a first-time mum to twins!  TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ How this 'grid doctor' maintains the health of Singapore's electricity network so everything stays on Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing

General Information 1.1 Purpose of this Document PowerGas is licensed by the Energy Market Authority (“Authority”) to be the Gas Transporter (“Transporter”) which owns, operates, and maintains the piped gas network in Singapore. SP PowerGrid (“SPPG”) is licensed by the Authority to be the Gas Transporter Agent to operate and maintain the piped gas network in Singapore on behalf of PowerGas. SPPG’s gas business is to plan, design, operate and maintain gas network assets in a manner that supports the delivery of safe, reliable, efficient, and quality services to customers. Under the Gas Transporter Licence, the Gas Transporter has to develop separate fees and charges for separate gas transportation services such as connection services and transportation services. This document sets out the connection policy and procedure for Natural Gas supply. 1.2 Singapore Gas Transportation System PowerGas owns an extensive gas transmission and distribution network throughout Singapore. The network is generally buried underground and transports natural gas to the western and northern parts of Singapore, and town gas to the whole of Singapore. The gas assets comprise the transmission network (operating at higher pressures), which forms the main reticulation backbone and the distribution network (operating at lower pressures). • Town gas is manufactured in Senoko Gasworks and delivered to approximately 900,000 customers in Singapore. The customers are made up of industrial, commercial, and residential gas users. Residential customers consist mainly of gas users from HDB, condominiums and landed premises. The town gas transmission network operates at 3 barg whereas the distribution network operates at pressure regimes ranging from 1 kPa to 50 kPa. Natural gas is supplied to about 200 customers and is imported from four sources (two submarine pipelines from Indonesia, one submarine pipeline from Malaysia and internationally through the Liquefied Natural Gas Terminal). Under the Gas Network Code, Gas Shippers/Retailers represent the customers that are connected to the natural gas networks. These natural gas customers are typically commercial or industrial and include all power stations. The natural gas transmission network operates mainly at two pressure regimes, 28 barg and 40 barg, and the distribution network operates at pressure regimes ranging from 3 barg to 6 barg.

Charges 4.1 Connection Policy The cost to connect a customer’s gas installation or gas fitting to the Transporter’s gas pipeline network varies from case-to-case, due to the proximity of the customer’s location and the cost of the materials and services required for the gas connection. Where possible, the Transporter will envisage to propose the most cost-effective connection to the applicant. 4.2 Connection Charge The connection charge payable for all gas connection applications is the sum of the project cost less the deductible cost, subject to a minimum connection charge of zero. The description of each of the cost components are shown below. (1) Project cost All costs related to the provision of gas connection from the Transporter’s gas pipeline network to the GSIV, including the Meter Installation (where applicable). (2) Deductible cost The Transporter’s investment value based on the committed gas demand from the applicant for the new gas connection. For distribution connections, the investment value is derived based on the net present value of the 5-Year revenue of the average consumption for each consumption category (see Appendix 8). For transmission connections, the connection charges are calculated individually on a case-bycase basis. In addition, a Last Mile Connection Charge (“LMCC”) will be levied to recover the cost of the “last mile” connection of the gas installation to the GSIV from the applicant. The natural gas transmission/distribution connection deductible cost, LMCC and unit rates used in the determination of the transmission/distribution pipeline estimated capital investment shall be reviewed and adjusted when deemed necessary by the Transporter. The Transporter reserves the right to review the connection charge paid for any new connection and seek reimbursement for the first 5 years under-recovered revenue from the Shipper/Retailer if the actual gas consumption after 5 years of operation is more than 10% below the projected gas demand declared during application. Natural Gas Connection Policy and Procedure Updated 1 Apr 24 Page 11 5. Unauthorised Connection and Supply of Gas In accordance with the Gas Act, any person who: • lays or causes to be laid gas pipe or fitting to connect to the gas network belonging to or managed by the Transporter without consent of the Transporter; • fraudulently abstracts, uses or consumes the supply of gas; • tempers any gas meter shall be guilty of an offence and shall be liable on conviction to a fine or imprisonment, or both.
