Singapore’s commitment to a low-carbon future is evident in the Singapore Green Plan 2030. This has led to a lot of growth and new ideas in the country’s renewable energy sector. Singapore is a city-state with limited land for large-scale solar farms, but it has become a center for cutting-edge renewable energy solutions, such as advanced floating solar and energy storage systems, regional power grids and next-generation biofuels.
We expect the renewable energy market in Singapore to continue its strong growth. This is because more businesses want green energy, the government supports it and the country is making smart investments in importing power from other countries. This ever-changing landscape is made up of a mix of big global energy companies, new companies from the region and specialized engineering firms that are all working to make clean energy a reality in the area.
This list shows five of the most important renewable energy companies in Singapore that have a strong presence and make a big difference. They are chosen because they are leaders in their field, have a large business, work on important national projects and have made contributions to the energy transition that can be verified by recent activities.
How we selected the top renewable energy companies
We made this list based on recent news about companies and market signals that we can see. This is not an official list. Companies were judged on things like their role in big renewable energy projects in Singapore, how big their business was in the local market, their strategic partnerships and import approvals from the Energy Market Authority (EMA) and how innovative they were in areas like solar, wind and low-carbon technologies.

How to choose the right renewable energy company in Singapore
First, please determine the size and nature of your project. Are you a government agency that wants to put solar panels on thousands of HDB blocks? EDPR Sunseap is a strong candidate because it has already shown that it can carry out the SolarNova program. If you are an industrial client in need of a large offshore wind substation, Seatrium’s global engineering skills are unparalleled.
Second, think about how your business works. If you don’t want to pay for a solar system on your commercial building up front, look for companies like EDPR Sunseap or others that offer solar leasing or Power Purchase Agreements (PPAs). Keppel’s “as-a-service” model for district cooling functions similarly to pay-as-you-go.
Third, think about how important it is to have firm power and connect to the grid. Companies that import energy or run big data centers that need clean power all the time, like Vena Energy, which focuses on firm power through battery storage, or Sembcorp, which offers integrated import solutions, are more relevant than pure-play solar developers.
Fourth, check the company’s financial health and history. Fourth, check the company’s financial health and history. Large energy projects require partners with substantial financial resources and a long-term commitment. Large energy projects require partners with substantial financial resources and a long-term commitment. Sembcorp’s robust balance sheet and Seatrium’s extensive engineering experience demonstrate this stability. This stability can be seen in Sembcorp’s strong balance sheet and Seatrium’s long history of engineering work.
A group of very smart and skilled companies is pushing Singapore’s renewable energy sector forward. Seatrium is the leader in offshore wind engineering, sending Singaporean know-how around the world. Keppel Infrastructure is changing the way energy works in the area with its “as-a-service” models for cooling and hydrogen-ready power that will last for a long time. EDPR Sunseap is the clear leader in putting solar power on rooftops all over the country. Sembcorp Industries has the money and the ability to handle big regional import projects all at once. Finally, Vena Energy is the future of firm, renewable energy because it combines huge storage with generation across borders.
Your project’s type, your financial goals and your long-term energy goals will all affect who the right partner is. Singaporean businesses and government agencies can confidently move forward with their work to make the energy future more sustainable and resilient by working with these top players.
Frequently asked questions
1. What types of renewable energy are most viable in Singapore?
Currently, solar energy is the most practical and widely used renewable energy source in Singapore. It is used on rooftops, in reservoirs (as floating solar farms) and the country imports power from various regions. There are shallow seas and a lot of shipping traffic near Singapore, so offshore wind isn’t a good option there. But Singaporean companies like Seatrium are world leaders in building infrastructure for offshore wind farms in other countries. Biofuels and sustainable aviation fuels (SAF) are a new area of growth.
2. How does Singapore plan to increase its renewable energy supply?
Singapore has a multi-pronged strategy: 1) Getting the most out of local solar energy use through programs like SolarNova. 2) A major goal for companies like Sembcorp and Vena Energy is to import renewable electricity from nearby countries like Indonesia and Malaysia through undersea cables. 3) Looking into low-carbon options like hydrogen, which will be used at Keppel’s new Sakra power plant.
3. What does an EMA conditional approval mean for energy imports?
An EMA Conditional Approval or Conditional License means that a proposed project to bring electricity into Singapore has passed initial tests for technical and commercial viability. It lets the project move on to the next licensing stages, but it doesn’t guarantee final delivery because there are still big problems to solve, like finalizing the routes for the subsea cables and getting all the necessary permits.
4. What is a solar leasing or Power Purchase Agreement (PPA)?
In a solar leasing or PPA model, a renewable energy company (like EDPR Sunseap) pays for, installs and owns the solar PV system on the roof of a building. The owner of the building then agrees to buy the electricity the system makes at a set price, which is usually lower than what the grid charges. This means that the building owner doesn’t have to spend any money up front.
5. Are Singapore renewable energy companies only focused on electricity?
No, companies are also involved in other areas, even though electricity generation is a big part of their business. Keppel Infrastructure is a leader in district cooling, which cools buildings without using electricity. There is also a growing interest in eco-friendly fuels. For example, Aether Fuels is working on a project in Singapore to make Sustainable Aviation Fuel (SAF).
6. How long does a large solar project take to pay back in Singapore?
The payback period for a solar system on a roof depends on things like how big the system is, how much electricity the building uses and the current price of electricity. Sites that use more power usually get their money back faster because they can use more of the power they make themselves, which makes grid electricity less expensive.
