Singapore energy mix & electricity
Electricity generation in Singapore reached 60.2 TWh in 2025. The supply is almost entirely natural gas, which accounted for 91.1% of generation; bioenergy made up most of the remainder (2.8%).

Singapore: electricity in context
Electricity generation in Singapore reached 60.2 TWh in 2025. That is similar to Peru. The supply is almost entirely natural gas, which accounted for 91.1% of generation; bioenergy made up most of the remainder (2.8%).
Renewables supplied 5.5% of the electricity, which ranks Singapore 136th of 158 countries (in the bottom quarter). This puts it 28 points below the world average of 33.8%. It is also below the average for Asia (27.3%). Generating one kWh emits about 497 g CO₂e here (world average: 458 g). The grid is more carbon-intensive than the world average. On carbon intensity, Singapore ranks 97th of 158 from the cleanest.
Since 2015, natural gas has added the most generation in absolute terms (+6.9 TWh), yet its share of the mix fell by 4.1 percentage points because other sources grew even faster. Measured by share of the mix, solar power gained most, up 2.7 percentage points. Taken together, the renewable share rose by 2.6 percentage points over the decade. Total generation grew by 9.9 TWh over the same period.
Wind and solar together provided 2.7% of electricity (solar 2.7%, wind 0%), compared with 17.3% worldwide. Per person, that is 279 kWh of solar electricity a year, versus a global average of 338 kWh.
Singapore generates 10,246 kWh of electricity per resident each year, 2.7 times the global average. Cross-border trade is roughly balanced.

Total energy: beyond electricity
Primary energy covers transport, heating and industry too. Renewables supply 0.5% of primary energy and fossil fuels 99.5% (2024). Per person, that is 180,700 kWh a year (world: 21,654).
Substitution method: non-fossil electricity is converted to the primary energy a fossil plant would have needed.
Power plants in Singapore
The WRI Global Power Plant Database lists 14 utility-scale plants in Singapore with a combined capacity of 13.7 GW. Gas plants account for the largest slice (70% of listed capacity). The biggest single plant is Senoko I-VII CCGT Power Plants Singapore (2,807 MW, Gas). The database was last updated in 2021, so newer wind and solar farms and rooftop PV are under-represented.
