Singapore’s solar energy sector continues to record strong growth, with the private sector playing a leading role in expanding the nation’s renewable capacity. According to the latest figures released by the Energy Market Authority, private companies account for 66% of Singapore’s total grid-connected solar capacity. By the third quarter of 2025, private installations had reached 1,273 megawatt-peak (MWp), marking a significant milestone in the country’s clean energy journey.
Overall, Singapore’s installed solar photovoltaic (PV) capacity rose to 1,932 MWp by the end of September 2025. This represents a 6% increase compared to the previous quarter, highlighting steady quarterly growth in deployment. The data reflects the growing participation of commercial and industrial players in supporting the country’s renewable energy ambitions.
Public sector initiatives also continue to contribute meaningfully. Town Councils and common services linked to public housing developments make up the second-largest share of solar capacity, contributing 436 MWp, or about 23% of the national total. Public service agencies account for 117 MWp, while residential homeowners contribute 105 MWp, each representing around 6% of the grid-connected capacity.
The expansion of solar installations forms a central part of Singapore’s broader energy transition strategy. The government has increased its solar deployment target to 3 gigawatt-peak (GWp) by 2030, aiming to strengthen energy security and reduce carbon emissions. In parallel, Singapore plans to raise its carbon tax to between $50 and $80 per tonne by the end of the decade to encourage cleaner energy adoption.
With consistent growth and strong private sector participation, Singapore remains on track to expand its renewable energy footprint and accelerate the shift toward a more sustainable power .
