Power generation is one of the major sources of carbon emissions. With our limited capacity to tap on alternative energy resources, we rely heavily on imported fossil fuel to power our nation.
Energy Reset: A More Environment-friendly Method to Power our Nation
As part of our energy transition and other initiatives under the Singapore Green Plan 2030, Singapore aims to tap on low-carbon energy sources across our economy. To further decarbonise the power sector, Singapore will harness and tap on four switches to transform our energy supply: solar, regional power grids, emerging low-carbon alternatives, and natural gas.
Solar remains the most promising renewable energy source for Singapore, while energy storage systems (ESS) allow us to counter the intermittency of renewable energy sources such as solar. We are working to accelerate solar deployment across Singapore.
Regional Power Grids.
We will explore ways to tap on regional power grids to access low-carbon electricity. We intend to bring in 4GW of low-carbon electricity imports by 2035.
Emerging Low-Carbon Alternatives.
We will look into emerging low-carbon solutions, e.g. carbon capture, utilisation and storage (CCUS) technologies, and hydrogen, that have the potential to help reduce Singapore’s carbon footprint.
Today, about 95% of Singapore’s electricity is generated using natural gas, the cleanest form of fossil fuels. Natural gas will continue to be a dominant fuel for Singapore in the near future as we scale up our other switches. We will work with the industry to improve the energy and carbon efficiency of natural gas generation units.
Since 2000, we have increased the percentage of natural gas used in electricity generation from 19 per cent to more than 95 per cent today. Among all fossil fuels, natural gas produces the least amount of carbon emissions per unit of electricity. By so doing, we have cut the amount of carbon we release into the atmosphere.
Our fuel mix makes us much less carbon intensive than many other nations that still use coal as an important part of their power generation.
Decreasing Our Fuel Oil Usage
Our electricity is produced by the combustion of natural gas that is piped from Malaysia and Indonesia. We have diversified our supply of natural gas with the opening of a liquefied natural gas (LNG) terminal on Jurong Island. There are further plans to build a second LNG terminal to support new industrial sites and power plants. This will not only provide critical mass for enhanced energy security, but it will also enable Singapore to be a hub for LNG-related businesses.

Finding Ways to Increase Solar Power Generation
Among the alternative energy options available to us, solar energy offers the most promising opportunity for Singapore. With the fall in solar photovoltaic (PV) panel prices, solar energy is currently economically comparable to electricity derived from fossil fuels.
To accelerate solar deployment in Singapore, the SolarNova programme has been launched, as a Whole-of-Government effort, to promote and aggregate solar demand across government agencies. Since 2015, four leasing tenders totalling 236 MWp of solar energy, have been awarded, with a fifth tender of 60 MWp awarded in 2020.
Singapore aims to deploy at least 2 GWp of solar by 2030, equivalent to the annual electricity needs of around 350,000 households in Singapore.
Grid-connected installed solar PV capacity in Singapore has grown significantly to 527 MWp as at end Q2 2021. This is contributed via the 4,750 installations across Singapore at:
- Non-residential private sector
- Town councils and grassroots units
- Public sector
- Residential estates
