The Mampuri Wind Farms (also known as the Senok Wind Farms, after its developers) are a set of three wind farms located near the Lakvijaya Power Station, on the Kalpitiya peninsula, in Mampuri, Puttalam District, Sri Lanka. The wind farms, referred to as Mampuri-I, Mampuri-II, and Mampuri-III, was built successively, and consists of eighteen Suzlonwind turbines ranging from 1.25 MW to 2.10 MW. Mampuri-I was commissioned on 22 March 2010, and was the first wind farm in the country to reach the 10 MW installed capacity threshold. As the government only allows projects up to 10 MW, the three wind farms are registered under three different company names, namely Senok Wind Power, Senok Wind Energy, and Senok Wind Resource.
Mampuri-I
Mampuri-I is built on a 5 km (3.1 mi) strip of land, and utilizes eight Suzlon S64-1.25MW wind turbines with rotor diameters of 64 m (210 ft) at rated wind speeds of 14 m/s (45.9 ft/s). Per the government's standardized power purchase agreement, the Ceylon Electricity Board pays Senok Rs. 20 (approximately US$ 0.176) for every kilowatt hour generated for the first eight years, followed by an adjusted rate thereafter. This phase created 40 jobs in the region, and cost Rs.3bn (US$ 26mn) to build. 55% of this was directly funded by Senok, with the remainder was funded by the World Bank.
Mampuri-II and Mampuri-III were constructed almost simultaneously after Mampuri-I. These wind farms utilizes five Suzlon S88-2.1 MW wind turbines each. The wind turbines measures 80 m (262 ft) tall, with rotor diameters of 88 m (289 ft), and has rated wind speed of 14 m/s (45.9 ft/s).
