The Pollupalai and Vallimunai Wind Farms are two wind farms built together by Joule Power and Beta Power, on the north-eastern shore of the Jaffna Lagoon, in Pachchilaipalli, Sri Lanka. Both wind farms are owned by the parent company Windforce, and have an installed capacity of 12 megawatts each,[1][2] and an annual production of approximately 60 GWh. The wind farms are the first-ever to be constructed in the Northern Province of Sri Lanka.[3]
Wind turbines
Both wind farms utilizes a total of sixteen ReGen V82 wind turbines, which has an installed capacity of 1.5 MW per turbine. The turbines operate at 9–17.3 RPM, and has a rotor diameter of 82 m (269 ft) and a swept area of 5,325 m2 (57,318 sq ft). The tubular tower section has a hub height of 85 m (279 ft), and is made up of four sections.[4]
The wind turbine's operating wind speed is 12.5 m/s (41 ft/s), with cut-in and cut-out wind speeds of 3 m/s (9.8 ft/s) and 22 m/s (72 ft/s) respectively. The turbines can survive wind speeds of up to 52.5 m/s (172 ft/s).[4] All 16 turbines are placed 400 m (1,300 ft) apart in a single row, facing the lagoon. The site's average wind speed is 7.5 m/s (25 ft/s), with an air density of 1.18 kg/m3 (0.074 lb/cu ft).[4]
