About Singapore's Energy Story

Singapore's energy sector has come a long way since its early days. Over the last 50 years, we have moved from oil to natural gas for cleaner power generation. We have also seen more of use of solar energy, particularly on rooftops and reservoirs.

With challenges brought about by climate change, we will need to change the way we use and produce energy. This is particularly so if our energy demand continues to rise with our economic development.


Advancing Singapore’s Energy Transition Towards A More Sustainable Future

Climate change is a global existential threat and Singapore is doing its part to reduce emissions for a more sustainable future. As announced by Minister for Finance Mr Lawrence Wong at Budget 2022, Singapore will raise our climate ambition to achieve net zero emissions by 2050.

The power sector has a key part to play as it accounts for about 40% of Singapore’s carbon emissions . We need to significantly reduce the power sector’s emissions, while ensuring that the power system remains secure, reliable and sustainable. Singapore is therefore harnessing four Switches – natural gas, solar, regional power grids and low-carbon alternatives – to transform its energy supply, while promoting energy efficiency to reduce demand.


Four Supply Switches for Power Sector Decarbonisation

Natural Gas

As Singapore transitions towards cleaner energy sources, reliable and sufficient energy sources are needed to ensure supply reliability. Natural gas will continue to be a dominant fuel for Singapore’s electricity generation even as we scale up the other 3 Switches. EMA is reviewing the emissions standards for fossil fuel-fired generation units, and expects to introduce the revised standards in 2023. EMA will also continue to diversify our natural gas sources and work with the power generation companies to improve the efficiency of their power plants.

Solar

Solar remains the most promising renewable energy source in the near term for Singapore. Today, over 670 megawatt-peak (MWp) of solar has been installed and we are on track to achieving our solar panel deployment target of at least 2 gigawatt-peak (GWp) by 2030, which could generate enough energy to meet the annual electricity needs of 350,000 households. Conventional rooftop solar has been complemented with innovative ways of deploying solar photovoltaic systems on spaces such as water bodies, temporary vacant land or sheltered walkways, making Singapore one of the most solar dense cities in the world. To manage the intermittent nature of solar and ensure grid resilience, we are planning to deploy at least 200 megawatt-hour (MWh) of energy storage systems (ESS).

Nonetheless, there are still limitations to the amount of solar energy that we can harness due to Singapore’s limited land area. Even as we work towards achieving our 2030 solar target of 2GWp, it will constitute only around 3% of the country’s total electricity demand in 2030.

Regional Power Grids

To overcome our land constraints, Singapore is tapping on regional power grids to access cleaner energy sources beyond its borders. Regional power grids can help accelerate the development of renewable energy projects in the region, bringing economic growth and increasing access to renewable energy. Electricity imports will also help us to diversify our energy sources away from natural gas and improve our energy resilience.

Singapore announced its target to have an import capacity of up to 4 gigawatts (GW) of low-carbon electricity by 2035, which could make up around 30% of Singapore’s projected electricity supply then. This will be done through a competitive Request for Proposal (RFP) process. Steps will also be taken to maintain our energy security, such as diversifying our import sources and ensuring back-up supply is in place to mitigate supply disruptions.

To pave the way for these electricity imports, EMA has been working with various partners on electricity import trials. These trials will allow us to assess and refine the technical and regulatory frameworks for importing electricity. They include a trial to import a capacity of 100MW of electricity from Peninsular Malaysia, as well as a pilot to import a capacity of 100MW of solar-generated electricity from Pulau Bulan, Indonesia. The Lao PDR-Thailand-Malaysia-Singapore Power Integration Project (LTMS-PIP), which imports a capacity of up to 100MW of renewable hydropower from Lao PDR to Singapore via Thailand and Malaysia via existing interconnections, also commenced on 23 June 2022.

Emerging Low-Carbon Alternatives

Singapore is exploring emerging low-carbon technologies such as hydrogen and carbon capture, utilisation and storage (CCUS) that can help reduce Singapore's carbon footprint in the longer term. While such technologies are nascent, the Government is taking active steps including investing in R&D through the Low-Carbon Energy Research (LCER) Funding Initiative. In 2021, $55 million was awarded to 12 projects to improve the technical and economic viability of implementing low-carbon technologies such as hydrogen and CCUS. An additional funding of $129 million was committed by the Government for Phase 2 of the LCER programme to further low-carbon technologies research.

Advances in geothermal technology have also opened up the opportunity for us to consider the prospect of tapping on this energy source for power generation. For instance, EMA is working closely with Nanyang Technological University, and various ministries and agencies including the Ministry of Trade and Industry and the National Climate Change Secretariat to conduct studies to determine the geothermal resource potential in Singapore.


Promoting Energy Efficiency to Manage Demand

Besides transforming the way we produce energy, managing our energy demand is also key to achieving a more sustainable future. With the economy recovering from the pandemic and as energy demand grows with increasing electrification, demand management will be a key pillar in supporting the energy transition. EMA will continue to encourage energy efficiency in the industry and households, and is concurrently developing other demand management initiatives. Together, everyone will have to play their part by conserving energy and supporting the greener energy transition for a more sustainable future.
