Hambantota Wind Farm

The Hambantota Wind Farm was a wind farm in Hambantota, Sri Lanka, owned and operated by the state-run Ceylon Electricity Board. The wind farm, which was located along south-eastern coast of Hambantota was the country's first wind farm, and consisted of five NEG Micon M1500-600 wind turbines of 600 KW each. With a total installed capacity of 3 MW, the wind farm generated up to approximately 4,500 MWh of power a year.[1][2]

The wind farm cost approximately Rs. 280 million (1999 rates) to build, 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 wind farm was decommissioned and dismantled in late 2018.[3][4]
