Solar energy is clean, generates no emissions, and can boost our energy security. We aim to increase our solar deployment to 1.5 gigawatt-peak (GWp) by 2025, and at least 2GWp by 2030.
Deploying solar power comes with challenges too. Solar power fluctuates depending on weather conditions such as the amount of sunlight, cloud movement and shade. Its intermittent nature could also affect our power system’s stability as we introduce more solar power into the grid.
There are potential trade-offs to consider as well. For example, when deploying floating solar panels on reservoirs, we need to minimise the impact on biodiversity . This could also mean forgoing reservoir space for recreational activities.
We are facilitating large-scale deployment of solar photovoltaic (PV) systems on:
Rooftops and Infrastructure
- Launched the SolarNova programme which aggregates demand for solar PV across government agencies. We are also looking into installing solar PV systems on the rooftops of public sector buildings.
- Reaching out to private developers and industry players to co-create solutions to maximise solar deployment on the rooftops of private industrial and commercial buildings.
Reservoirs and Offshore Spaces
- Constructed a 60 megawatt-peak (MWp) inland floating solar farm on Tengeh Reservoir.
- Constructing two 1.5MWp solar PV systems on Bedok and Lower Seletar reservoirs. These floating solar PV systems can potentially generate enough electricity to power around 800 four-room HDB flats .
- Investing in R&D efforts to develop and help bring down the costs of innovative solar applications. For example, building-integrated photovoltaics(BIPV) has the could potentially of replace conventional building materials for building facades and vertical surfaces (e.g. noise barriers and fences) to generate solar power.
- Introduced the SolarLand programme which uses re-deployable solar panels for ease of deployment at alternative locations in the event that the current plot of land needs to be developed.
Overcoming Solar Intermittency
- Energy Storage Systems (ESS) allow us to address the intermittent nature of solar energy. ESS systems work like large-scale batteries which can store solar power harnessed for later use.
- Deploying ESS will also ensure that our power system remains stable, as more solar power is integrated into our energy mix.
- Our target is to deploy 200 megawatt (MW) of ESS beyond 2025. Find out more about our ESS initiatives.
What is the Government doing to help you?
- Partnered Shell in nurturing local energy start-ups in capability-building and funding for solutions in areas such as ESS.
- Partnered Sembcorp Industries and PSA Singapore under the ACCelerating Energy Storage Systems for Singapore (ACCESS) programme to pilot use cases, design business models and facilitate regulatory and market approvals to operate ESS.
- Partnered Keppel Offshore & Marine to develop innovative solutions such as the first floating ESS in Singapore and the first-of-its-kind battery stacking solution.
What can individuals do?
- Consider opting for green electricity plans.
- If you live in a landed property, consider installing solar PV systems and use solar energy to power your home.
- Share ideas on how we can deploy more solar PV systems in Singapore. Suggestions could include possible locations and areas where we can install solar PV systems.

Regional Power Grids
Tapping on regional power grids is one of the ways we can access sustainable energy resources that would otherwise be unavailable or limited in land-scarce Singapore. This move could also help us to meet the rising electricity demand here.
What is the Government doing?
- We are going to trial the import of 100 megawatts (MW) of electricity from Malaysia. This trial will help to build the know-how to scale up clean energy imports from the region.
- Exploring cross-border power trade of up to 100MW under the Laos PDR-Thailand-Malaysia-Singapore Power Integration Project.
Emerging technologies such as hydrogen and carbon capture, utilisation and storage (CCUS) which can potentially help us further reduce our carbon emissions in the longer-term.
- Has the potential to diversify our fuel mix across a number of applications, such as electricity generation and transport (e.g. in ships and aircrafts). If produced from renewable energy sources, it could also help to decarbonise power generation and emissions-heavy sectors.
Carbon capture, utilisation & storage (CCUS)
- Process of capturing carbon dioxide produced from emission sources such as power plants, and converting it into usable products (e.g. building materials, chemicals and synthetic fuels), or transporting it to a storage site and depositing it to prevent it from entering the atmosphere. This enables us to create greener energy as a result.
- However, there are factors to consider if we wish to adopt these low-carbon alternatives. For instance, our current infrastructure needs to be improved extensively to be able to support the use of hydrogen (e.g. for hydrogen transportation, storage and utilisation). Costs for carbon capture are also considered high at the moment.
How is the Government helping you?
- Commissioned studies to better understand the technical and economic feasibility of importing hydrogen and its use in potential downstream applications in Singapore, and the potential for CCUS pathways to reduce Singapore’s carbon emissions in the longer term.
- Working with the industry and the research community to find ways to overcome the challenges of adopting hydrogen and CCUS technologies.
What can businesses or researchers do?
- Share your ideas here on how we can leverage low-carbon alternatives to enable decarbonisation.
Today, about 95% of our electricity is generated using imported natural gas. As a small country with limited natural resources, there are limitations on how we can deploy renewable energy sources including solar. Hence, natural gas will remain a key fuel source while we find ways to scale up renewable energy deployment.
Solar power is our most viable renewable energy option but has its limitations too, such as intermittency. This means that natural gas will remain a key fuel source even as we scale up our renewable energy deployment.
How is the Government helping you?
- Launched Singapore’s first LNG Terminal in 2013 to import natural gas from around the world. This has helped in diversifying our sources of natural gas and enhancing our energy security.
- Launched the Genco Energy Efficiency Grant where EMA will support energy efficiency projects. Each project must result in measurable and verifiable carbon abatement of at least 0.5 kilo-tonnes per annum (ktpa).
