Top 8 Renewable and Green Energy Companies in Singapore (2026)

[Updated, October 2026]

Key Takeaways:
Natural gas still supplies over 90% of Singapore's electricity, so solar leads the country's green energy push, with over 2 GWp installed and a 3 GWp target for 2030. This guide covers 8 renewable energy companies across solar, hydrogen, wind, tidal and waste-to-energy, including how businesses and solar owners can use Renewable Energy Certificates (RECs).

Singapore is swiftly transitioning towards a greener future, embracing renewable and green energy solutions to meet its growing power needs while mitigating environmental impact. This guide spotlights 8 leading renewable energy companies in Singapore making strides in solar energy, hydrogen, wind, tidal and waste-to-energy sectors, plus a quick look at the country's biggest energy companies and where they fit in.

What Does Renewable Energy in Singapore Look Like in 2026?

Natural gas still generates most of Singapore's electricity: 93.1% of the fuel mix in the first half of 2025, with solar at 2.5%, according to the Energy Market Authority (EMA).

Solar is the country's most viable local source of green energy. Singapore passed 2 gigawatt-peak (GWp) of solar deployment at the end of 2025 and targets 3 GWp by 2030, per the National Climate Change Secretariat. Land and cloud cover cap how far solar can go. For that reason, EMA also plans to import around 6 GW of low-carbon electricity by 2035, about one-third of demand by then.

Hydrogen, wind, tidal and waste-to-energy play smaller roles. Here's where each company in this guide fits:

Of these, solar is the only green energy solution a homeowner can adopt directly today. The rest serve industry, government or overseas projects.

What About Singapore's Biggest Energy Companies?

If you searched for energy companies in Singapore, you may have expected SP Group, Sembcorp, Keppel or Tuas Power. These firms run the national grid and the gas-fired plants that supply most of the country's electricity, so they sit outside a renewables-only list.

Several are building green capacity too. Sembcorp operates the 60 MWp floating solar farm at Tengeh Reservoir, which spans 45 hectares with around 120,000 panels. An SP Group subsidiary is the technical partner for Singapore's electricity import grid. Gas will stay central for years, though: in August 2026, EMA awarded Tuas Power a new 670 MW gas plant due in 2031.

For households, the Open Electricity Market lets you choose your electricity retailer. The most direct way to use green energy at home is still rooftop solar.

Frequently Asked Questions

Does Singapore use wind energy?

Barely. Low wind speeds and limited land make large turbines impractical, so Singapore's wind expertise goes into offshore wind infrastructure for overseas projects.

What is the main renewable energy source in Singapore?

Solar. Singapore had over 2 GWp installed by the end of 2025 and aims for 3 GWp by 2030.

What is the best green energy solution for a Singapore home?

For landed homeowners, rooftop solar is the most practical option. It cuts your SP Group bill directly, and you can sell excess electricity back to the grid.
