The Hambantota Wind Farm is the first wind farm to be commissioned in Sri Lanka. The farm is located along south-eastern coast of Hambantota, and consists of five NEG Micon M1500-600 wind turbines of 600 KW each. With a total installed capacity of 3 MW, the wind farm generates up to approximately 4,500 MWh of power annually.[1][2]

The wind farm stretches about 1,500 km2 (580 sq mi) in size, and cost approximately Rs.280 million (1999 rates), of which 34% were local funds and 66% were foreign funds.[1][2] Foreign funds were raised by the Global Environmental Facility and the World Bank. Studies on the project dated as early as 1988, more than a decade before it was commissioned in 1999. The project is now owned by the Ceylon Electricity Board.
