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. The Transporter may disconnect the premises of, or the gas retailer may discontinue supply of gas to the premises of, the person.
