Global GridSeychelles' energy mix and electricity
🇸🇨 In 2024, Seychelles generated 0.63 TWh of electricity. The largest source was oil and other fossil fuels at 84%, followed by solar (14%) and wind (1.6%). In total, 16% came from low-carbon sources (nuclear and renewables) and 84% from fossil fuels.
On average, each kilowatt hour produced about 556 grams of carbon dioxide (CO₂), above the world average of 458 grams in 2025.
Electricity demand was 0.63 TWh. Its electricity imports and exports were roughly in balance.
Since 2000, electricity generation has grown by 215%, from 0.20 TWh. The low-carbon share went from 0% to 16%. The biggest rise was in solar, from 0% to 14% of generation. The biggest fall was in oil and other fossil fuels, from 100% to 84%. Carbon intensity fell from 650 to 556 grams per kWh.

Energy security score
Vulnerable. It is not ranked because its power system is very small. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted. It is based on 4 of the 5 measures.
| Measure | Score |
|---|---|
| Produces its own energy No reliable figure exists for Seychelles, so this measure is left out and the other four count for more. | n/a |
| Variety of power sources How evenly generation is spread across nine sources. The largest, oil and other fossil fuels, made 84%. | 31 |
| Little reliance on imported power Seychelles exported more electricity than it imported, so it scores full marks. | 100 |
| Low-carbon power Nuclear and renewables made 16% of generation. | 16 |
| Low gas and oil use Gas and oil made 84% of generation; the score is 100 minus that share. | 16 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
