160 years, working behind the scenes
Our story began in 1861 as Singapore Gas Company, a public company supplying gas for street lamps. The next year, Kallang Gasworks began producing gas from coal and was strategically located for easy access to coal supplies shipped in. People used our piped town gas in their daily lives, for cooking and water heating.


Development through the years
From the early 1950s, we started supplying piped town gas to HDB flats, private condominiums, landed properties as well as commercial and industrial customers.
Along the way, the company underwent several name changes – the City Council of Singapore (before 1965), Public Utilities Board (1965 to 1994) and PowerGas Ltd (1995 to 2001). In January 2002, City Gas Pte. Ltd. was formed as a divested entity from PowerGas Ltd. and continued as a piped town gas producer and retailer.
Today, as City Energy Pte. Ltd. (as Trustee of City Energy Trust), we are a fully-owned subsidiary of Keppel Infrastructure Trust.
Key Milestones
We were founded as the Singapore Gas Company.
Kallang Gasworks was built to produce piped town gas.
The Singapore Municipal Commissioners took over the operations of the Singapore Gas Company to extend the gas supply network to street lighting. By 1940, the gas pipe network had been rapidly expanded though gas was used more for cooking and heating water than for lighting.
We became part of the Public Utilities Board, and oil gasification plants were replaced by naphtha gas-making plants.
The Electricity and Gas Departments of the Public Utilities Board were corporatised to form Singapore Power.
Senoko Gasworks that will replace the production in Kallang officially opened – a S$240 million facility with a production capacity of 1.6 million cubic metres of gas per day.
Kallang Gasworks officially ceased operations in March 1998. All gas operations were officially moved to Senoko Gasworks, which is still producing town gas to date.
City Gas Pte Ltd was formed as a divested entity from PowerGas Ltd on
2 January 2002.
Natural gas from South Sumatra, Indonesia, began being piped to Singapore. The natural gas was also used as partial feedstock to produce town gas.
We achieved our 500,000th customer milestone.
City Gas Trust was constituted as a private trust on 5 January 2007, and a wholly owned subsidiary of CitySpring Infrastructure Trust.
We achieved our 600,000th customer milestone.
City Gas celebrated our 150th anniversary. We had a year-long celebration and planted a time capsule at the production building lobby.
We achieved our 700,000th customer milestone.
CitySpring Infrastructure Trust was enlarged on 18 May 2015, and renamed as Keppel Infrastructure Trust.
We achieved our 800,000th customer milestone.
We are rebranded as City Energy.
