Saint Lucia energy mix & electricity
In 2024, Saint Lucia generated 400 GWh of electricity. The supply is almost entirely oil, which accounted for 97.5% of generation; solar power made up most of the remainder (2.5%).
The power system is very small (under 1 TWh a year), so it is not included in share-based world rankings. A single plant can change its mix dramatically from one year to the next.

Saint Lucia: electricity in context
In 2024, Saint Lucia generated 400 GWh of electricity. That is similar to Somalia. The supply is almost entirely oil, which accounted for 97.5% of generation; solar power made up most of the remainder (2.5%).
The renewable share stood at 2.5%. This puts it 31 points below the world average of 33.8%. It is also below the average for North America (28.8%). The carbon intensity of electricity is 650 g CO₂e/kWh; the global average is 458 g/kWh. That makes it one of the more carbon-intensive grids in the world.
Taken together, the renewable share rose by 2.5 percentage points over the decade. Total generation grew by 20 GWh over the same period.
Coal has never been part of the power mix in Saint Lucia in any meaningful way.
Wind and solar together provided 2.5% of electricity (solar 2.5%, wind 0%), compared with 17.3% worldwide. Per person, that is 56 kWh of solar electricity a year, versus a global average of 338 kWh.
Saint Lucia generates 2,225 kWh of electricity per resident each year, 58% of the global average. Saint Lucia does not trade electricity with other countries: the grid is not interconnected with any neighbour.
