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]
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]
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.
Albany wind and Grasmere farms are two wind power stations near Albany, Western Australia, owned by Bright Energy Investments. They are adjacent and are often considered a single facility. They have 18 wind turbines, with a maximum generating capacity of 35.4 MW of electricity. The original Albany Wind Farm was commissioned in October 2001, after ten years of planning. The wind farm has the capacity to produce 80 per cent of the electricity requirements of Albany.
Wind power generation capacity in India has significantly increased in recent years. As of 31 March 2024, the total installed wind power capacity was 45.887 gigawatts (GW). India has the fourth largest installed wind power capacity in the world. Wind power capacity is mainly spread across the southern, western, and northwestern states.
Offshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of capacity installed. Offshore wind farms are also less controversial than those on land, as they have less impact on people and the landscape.
The electricity sector in Sri Lanka has a national grid which is primarily powered by hydroelectric power and thermal power, with sources such as photovoltaics and wind power in early stages of deployment. Although potential sites are being identified, other power sources such as geothermal, nuclear, solar thermal and wave power are not used in the power generation process for the national grid.
Teesside Wind Farm, or alternatively referred to as Redcar Wind Farm, is a 27 turbine 62 MW capacity offshore wind farm constructed just to the east of the mouth of the River Tees and 1.5 km north of Redcar off the North Yorkshire coast, in the North Sea, England.
The Mampuri Wind Farms 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 Suzlon wind 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.
The Seguwantivu and Vidatamunai Wind Farms are two legally separate wind farms built together by Seguwantivu Wind Power and Vidatamunai Wind Power, on the south-east shore of the Puttalam Lagoon, in Puttalam, Sri Lanka.
Wind power in Hawaii is produced by the state's 132 commercial wind turbines, totaling 236 MW in capacity. In 2015, wind turbines produced 6.4% of Hawaii's electricity. In 2012, Hawaii generated 367 million kWh from wind power.
The Uppudaluwa Wind Farm is a 10.5 MW wind farm owned by PowerGen Lanka (Private) Limited in Uppudaluwa, Puttalam, Sri Lanka.
Wind power in Thailand amounted to an installed production capacity of 224.5 MW as of the end of 2014. Installed capacity was 112 MW at the end of 2012, with 111 MW added in 2013, and a minor amount added in 2014. This ranked Thailand 46th in the world by installed capacity as of 2015.
Çanta Wind Farm is a 2014 wind power plant consisting of 19 wind turbines with a total installed capacity of 47.5 MW. The wind farm is in Çanta in the Silivri district of Istanbul Province, northwestern Turkey.
The Madurankuliya Wind Farm is a 12 MW wind farm located in Narakkaliya, bordering the Lakvijaya Power Station, in Narakkaliya, Puttalam, Sri Lanka. The wind farm is operated by Daily Life Renewable Energy (Pvt) Ltd, a subsidiary of WindForce (Pvt) Ltd, which owns most of the existing wind farms in the country. The facility consists of eight ReGen VENSYS 82 wind turbines of 1.5 MW each. With a hub height of 85 m (279 ft) and a rotor diameter of 82 m (269 ft), these turbines has rated wind speeds of 13 m/s (43 ft/s), despite the site only experiencing about 7.4 m/s (24 ft/s). The wind farm experiences air densities of 1.158 kg/m3 (0.072 lb/cu ft).
The Pawan Danavi Wind Farm is a 10.2 MW onshore wind farm located near Kalpitiya, in the Puttalam District of Sri Lanka. The wind farm utilizes twelve of Gamesa's G58-850 kW wind turbines. Pawan Danavi is a subsidiary company of LTL Holdings.
Wind power in Rhode Island is in the early stages of development. There are several small scale wind turbine projects in the state. As of December 2013 there were 11 turbines at 10 sites in the state. In 2014, Rhode Island had 9 MW of installed wind power capacity, which quickly rose to 75 MW in 2019.
The Thambapavani Wind Farm named after Thambapanni and Pavan meaning wing in Sinhalese. Also called Mannar Island Wind Farm or Mannar Wind Farm) is a 100-megawatt wind farm which was built on the southern coast of the Mannar Island, in Sri Lanka. The project would cost approximately US$200 million, 78% of which will be borne by the Asian Development Bank, while the remaining 22% will be borne by the developers, the Ceylon Electricity Board. Identification of land plots and ownership has already begun. It is currently regarded as the largest wind farm in Sri Lanka and it is also the first wind power plant to be owned by the Ceylon Electricity Board.
