The use of fossil fuels to power Singapore results in carbon emissions. Clean energy sources can help us meet our energy needs while minimising our environmental impact.
Singapore is an ‘alternative energy-disadvantaged’ country, as recognised under the United Nations Framework Convention on Climate Change (UNFCCC). Our small land area, location and other physical attributes make it hard for us to adopt alternative energy sources such as hydroelectricity, wind energy and geothermal energy. Solar power is the most viable option, and we have increased our use of solar energy in recent years. Nonetheless, it is limited by factors such as space constraints, cloud cover and humidity.
Our goal is to build a sustainable future energy mix by harnessing the four supply switches of natural gas, solar, regional power grids, and emerging low-carbon alternatives.
We have set a target to deploy at least 2 GWp of solar by 2030. This will meet around 10% of peak daily electricity demand today, enough to power around 350,000 households in Singapore. We are pursuing innovative approaches to solar deployment to overcome our space constraints, such as deploying floating solar photovoltaic (PV) systems on our reservoirs and offshore waters. This includes Singapore’s first large-scale floating solar PV system of 60 MWp at Tengeh Reservoir, which will be one of the world’s largest upon completion in 2021. It will generate enough energy to meet the daily needs of Singapore’s waterworks.
To enable longer-term decarbonisation, we are exploring the use of emerging low-carbon solutions. These include carbon capture, utilisation and storage (CCUS) and low-carbon hydrogen.
