From the Renewable Energy India Expo website:

The Sri Lankan government aims to be an energy self-sufficient nation by 2030. The objective is to increase the power generation capacity of the country from the existing 4,043 megawatts (MW) to 6,900 MW by 2025 with a significant increase in renewable energy. Sri Lanka has already achieved a grid connectivity of 98 percent, which is relatively high by South Asian standards. Electricity in Sri Lanka is generated using three primary sources: thermal power (which includes coal and fuel oil), hydropower, and other non-conventional renewable energy sources (solar power and wind power).
