63-596: The Hau Nui Wind Farm is a 15-turbine wind farm located approximately 21 kilometres (13 mi) south-east of Martinborough , in the South Wairarapa District of New Zealand . Hau Nui ( Māori for "big wind") was the first wind farm built in New Zealand. The wind farm was built in two stages and the completed capacity is 8.65 MW. Originally owned by Genesis Energy , in October 2024 the farm

126-470: A Battery storage power station located adjacent to the Devers electrical substation. Phase I of the facility came online in 2023, while Phase II is anticipated in the coming years. Southern California Edison operates several high-voltage electrical transmission lines through the pass, leading to and from its Devers substation located north of Palm Springs. Path 46 500 kilo- volt (kV) power lines cross

189-567: A landmark and curiosity until it was taken down and sold for scrap in 1942. Southern California Edison opened its Wind Energy Center eight miles northwest of Palm Springs in 1980 near its Devers substation, installing two wind turbine generators for testing. One of these was the SWT-3 horizontal axis wind turbine generator designed by Charles Schachle and produced by the Bendix Corporation . It featured three 82.5-foot blades mounted on

252-530: A large funnel on the front to concentrate the wind's power. They set the entire device on a circular rail that allowed it to be pivoted to face prevailing winds . The powerful wind quickly burned out the 25,000 watt unit, but a larger unit was obtained from the Pacific Electric substation in Los Angeles. After the two worked out other mechanical issues, Oliver set out to raise funds to expand

315-529: A list of capable areas is constructed, the list is refined based on long term wind measurements, among other environmental or technical limiting factors such as proximity to load and land procurement. Many independent system operators (ISOs) in the United States such as the California ISO and Midcontinent ISO use interconnection request queues to allow developers to propose a new generation for

378-481: A maximum capacity of 1.65 MW, for a total of 24.75 MW. The 15 on-shore turbines are spaced 326 metres (1,070 ft) apart, each 70 metres (230 ft) high, with 41 metres (135 ft) long blades, with a rotor diameter of 82 metres (269 ft) and a wind swept area of 5,281 square metres (56,840 sq ft). Phase II was completed in August 2008, and added 5 more wind turbines with the same capacity, and brought

441-430: A minimum of 3.5 times the turbine's rotor diameter of clear space between each adjacent turbine's respective spatial envelope. Closer spacing is possible depending on the turbine model, the conditions at the site, and how the site will be operated. Airflows slow as they approach an obstacle, known as the 'blockage effect', reducing available wind power by 2% for the turbines in front of other turbines. The capacity of

504-591: A rotor standing 110 feet above the ground. The SWT-3 never achieved its rated power production due to losses in its hydraulic drive, limiting electric output to 1.1 MW. The second turbine tested at the Edison site was a 500-kilowatt vertical axis wind turbine generator produced by Alcoa. The Alcoa unit self-destructed just two weeks after installation in 1981 on the eve of the first American Wind Energy Conference in Palm Springs. In 1982 wind energy development in

567-499: A single wind turbine for testing purposes have been built. One such installation is Østerild Wind Turbine Test Field . Airborne wind farms have been envisaged. Such wind farms are a group of airborne wind energy systems located close to each other connected to the grid at the same point. Wind farms consisting of diverse wind turbines have been proposed in order to efficiently use wider ranges of wind speeds. Such wind farms are proposed to be projected under two criteria: maximization of

630-460: A specific given area and grid interconnection. These request queues have both deposit costs at the time of request and ongoing costs for the studies the ISO will make for up to years after the request was submitted to ascertain the viability of the interconnection due to factors such as ATC. Larger corporations who can afford to bid the most queues will most likely have market power as to which sites with

693-465: A total capacity of 539 MW. An important limiting factor of wind power is variable power generated by wind farms. In most locations the wind blows only part of the time, which means that there has to be back-up capacity of dispatchable generation capacity to cover periods that the wind is not blowing. To address this issue it has been proposed to create a " supergrid " to connect national grids together across western Europe , ranging from Denmark across

756-408: A total of fifteen Enercon E-40 wind turbines. The seven Stage 1 turbines are third-generation turbines, delivering 550 kW each. The eight Stage 2 turbines are later versions of the same Enercon E-40 model, each generating 600 kW each. The turbines in both stages are 46 metres (151 ft) tall to the hub, and have rotor diameters of 40 metres (131 ft). Electricity generated by Hau Nui

819-648: A tunnel like pass towards areas of lower pressure and flatter land. Passes used for wind farms like the San Gorgonio Pass and Altamont Pass are known for their abundant wind resource capacity and capability for large-scale wind farms. These types of passes were the first places in the 1980s to have heavily invested large-scale wind farms after approval for wind energy development by the U.S. Bureau of Land Management. From these wind farms, developers learned much about turbulence and crowding effects of large-scale wind projects, which were previously unresearched, in

882-803: Is a German wind turbine manufacturer. In the end of 2011 49.6 MW was expected to be completed. The Pakistani government also issued a Letter Of Interest in a 100 MW Wind power plant to FFCEL. The Pakistani government had plans to achieve electric power generation of up to 2500 MW by the end of 2015 from wind energy to bring down an energy shortage. Currently four wind farms are operational (Fauji Fertilizer 49.5 MW (subsidiary of Fauji Foundation), Three Gorges 49.5 MW, Zorlu Energy Pakistan 56 MW, Sapphire Wind Power Company Limited 52.6 MW) and six are under construction phase ( Master Wind Energy Limited 52.6 MW, Sachal Energy Development Limited 49.5 MW, Yunus Energy Limited 49.5 MW, Gul Energy 49.5 MW, Metro Energy 49.5 MW, Tapal Energy) and were expected to achieve COD in 2017. In

945-416: Is critical to the overall success of a wind farm. Additional conditions contributing to a successful wind farm location include: wind conditions, access to electric transmission, physical access, and local electricity prices. The faster the average wind speed, the more electricity the wind turbine will generate, so faster winds are generally economically better for wind farm developments. The balancing factor

1008-408: Is crucial to determining site potential in order to finance the project. Local winds are often monitored for a year or more, detailed wind maps are constructed, along with rigorous grid capability studies conducted, before any wind generators are installed. The wind blows faster at higher altitudes because of the reduced influence of drag. The increase in velocity with altitude is most dramatic near

1071-449: Is finding areas with adequate available transfer capability (ATC). ATC is the measure of the remaining capacity in a transmission system available for further integration of two interconnected areas without significant upgrades to existing transmission lines and substations. Significant equipment upgrades have substantial costs, potentially undermining the viability of a project within a location, regardless of wind resource availability. Once

1134-403: Is injected into the local distribution grid. The 400 V electricity generated by each turbine is stepped up by transformers at the base of the turbine - to 11,000 V for stage 1 turbines and 33,000 V for stage 2 turbines. 33 kV lines from stage 2 take electricity 24 kilometres (15 mi) to Martinborough to supply the town. Stage 1 turbines connect to 11 kV lines to supply

1197-436: Is low, some electricity may be exported to the national grid through Transpower's Greytown substation. Wind farm A wind farm or wind park , 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 . Many of

1260-597: Is pursuing several proposed locations in the Great Lakes , including the suspended Trillium Power Wind 1 approximately 20 km from shore and over 400 MW in size. Other Canadian projects include one on the Pacific west coast. In 2010, there were no offshore wind farms in the United States, but projects were under development in wind-rich areas of the East Coast, Great Lakes, and Pacific coast; and in late 2016

1323-511: Is somewhat understated, since the official database counts the latest repowered turbines but does not include their power output. In December 2021 the site hosted more than 1,220 turbines, down from a peak of more than 4,200 in 1987. The reduction is the result of repowering, where many small, obsolete turbines are replaced with fewer, larger turbines. The San Gorgonio Pass is now home to the Desert Peak Energy Facility,

1386-465: Is that strong gusts and high turbulence require stronger more expensive turbines, otherwise there is a risk of damage. The average power in the wind is not proportional to the average wind speed. For this reason, the ideal wind conditions would be strong but consistent winds with low turbulence coming from a single direction. Mountain passes are ideal locations for wind farms under these conditions. Mountain passes channel wind, blocked by mountains, through

1449-566: Is the first wind power plant in Pakistan. The wind farm is being developed in Jhimpir, by Zorlu Energy Pakistan the local subsidiary of a Turkish company. The total cost of the project is $ 136 million.[3] Completed in 2012, it has a total capacity of around 56MW. Fauji Fertilizer Company Energy Limited, has built a 49.5 MW wind Energy Farm at Jhimpir. Contract of supply of mechanical design was awarded to Nordex and Descon Engineering Limited. Nordex

1512-480: The Block Island Wind Farm was commissioned. Installation and service / maintenance of off-shore wind farms are a challenge for technology and economic operation of a wind farm. As of 2015 , there are 20 jackup vessels for lifting components, but few can lift sizes above 5 MW. Service vessels have to be operated nearly 24/7 (availability higher than 80% of time) to get sufficient amortisation from

1575-752: The Western Cape region. These include the 100 MW Sere Wind Farm and the 138 MW Gouda Wind Facility . Most future wind farms in South Africa are earmarked for locations along the Eastern Cape coastline. Eskom has constructed one small scale prototype windfarm at Klipheuwel in the Western Cape and another demonstrator site is near Darling with phase 1 completed. The first commercial wind farm, Coega Wind Farm in Port Elisabeth,

From this funding as well as $ 80 million from the Sri Lankan Government and $ 60 million from France's Agence Française de Développement, Sri Lanka was expected to build two 100MW wind farms from 2017 due to be completed by late 2020 in northern Sri Lanka. As of September 2015, a number of sizable wind farms have been constructed in South Africa mostly in

1701-608: The Chinese wind industry appeared unaffected by the financial crisis of 2007–2008 , according to industry observers. According to the Global Wind Energy Council , the development of wind energy in China, in terms of scale and rhythm, is unparalleled in the world. The National People's Congress permanent committee passed a law that requires the Chinese energy companies to purchase all the electricity produced by

1764-547: The Gharo wind corridor, two wind farms (Foundation Energy 1 & II each 49.5 MW) are operational while two wind farms Tenaga Generasi Limited 49.5 MW and HydroChina Dawood Power Pvt. Limited 49.5 are under construction and expected to achieve COD in 2017. According to a USAID report, Pakistan has the potential of producing 150,000 megawatts of wind energy, of which the Sindh corridor can produce 40,000 megawatts. The Philippines has

1827-576: The Netherlands, Norway, Sweden and the United Kingdom, with a combined operating capacity of 2,396 MW. More than 100 GW (or 100,000 MW) of offshore projects are proposed or under development in Europe. The European Wind Energy Association set a target of 40 GW installed by 2020 and 150 GW by 2030. As of 2017 , The Walney Wind Farm in the United Kingdom is the largest offshore wind farm in

1890-573: The San Gorgonio Pass area was formally studied, and the results published in the San Gorgonio Wind Resource Study EIR (1982), a joint environmental document prepared for the U.S. Bureau of Land Management and Riverside County. The document assessed three scenarios for wind energy development in the area and included criteria for the development of wind energy on both a countywide basis and specifically for

1953-413: The San Gorgonio Pass area. The first commercial wind farm was established by San Gorgonio Farms on a land parcel adjacent to the Devers substation, consisting of eight 25-kiloWatt downwind turbines. By 1987, fourteen independent operators had installed over 4200 wind turbines in the area. Since then, many wind projects have changed owners and others were repowereed, replacing many older wind turbines at

2016-468: The U.S. due to the lack of operational wind farms large enough to conduct these types of studies. Usually sites are screened on the basis of a wind atlas , and validated with on-site wind measurements via long term or permanent meteorological-tower data using anemometers and wind vanes . Meteorological wind data alone is usually not sufficient for accurate siting of a large wind power project. Collection of site specific data for wind speed and direction

2079-736: The country's economy. With its large land mass and long coastline, China has exceptional wind resources. Researchers from Harvard and Tsinghua University have found that China could meet all of their electricity demands from wind power by 2030. By the end of 2008, at least 15 Chinese companies were commercially producing wind turbines and several dozen more were producing components. Turbine sizes of 1.5 MW to 3 MW became common. Leading wind power companies in China were Goldwind , Dongfang Electric , and Sinovel along with most major foreign wind turbine manufacturers. China also increased production of small-scale wind turbines to about 80,000 turbines (80 MW) in 2008. Through all these developments,

2142-575: The country's power. In Japan's electricity sector , wind power generates a small proportion of the country's electricity. It has been estimated that Japan has the potential for 144 gigawatts (GW) for onshore wind and 608 GW of offshore wind capacity. As of 2023, the country had a total installed capacity of 5.2 GW. As of 2018, government targets for wind power deployment were relatively low when compared to other countries, at 1.7% of electricity production by 2030. The 117 MW Tafila Wind Farm in Jordan

2205-509: The countryside", habitat loss , and a drop in tourism. Some critics claim that wind farms have adverse health effects, but most researchers consider these claims to be pseudoscience (see wind turbine syndrome ). Wind farms can interfere with radar, although in most cases, according to the US Department of Energy, "siting and other mitigations have resolved conflicts and allowed wind projects to co-exist effectively with radar". Location

2268-544: The end of their useful lifetime with fewer but larger new ones. Today the turbines range from 80 feet (24 m) to 300 feet (91 m) in height. The recent repower projects included: All of these 2020-era repowering efforts installed Vestas V112 or V117 wind turbines, producing between 3.0 and 4.3 MW, the largest blade reaching 492 feet above the ground. Note the permitted projects often allow for more new turbines than actually installed. The as-installed number of turbines are listed. A 2008 proposal details an upgrade to

2331-474: The energy produced by the farm and minimization of its costs. The Australian Greens have been significant supporters of Australian wind farms, however the party's previous leader Bob Brown and former leader Richard Di Natale have now both expressed concerns about environmental aspects of wind turbines, particularly the potential danger they impose for birds. In July 2022 Brazil reached 22 GW of installed wind power in about 750 wind farms In 2021 Brazil

2394-558: The enterprise, with the vision of powering all of nearby Palm Springs . Oliver incorporated the Oliver Electric Power Corporation in Reno, Nevada , began selling stock in the company, but quickly ran afoul of newly enacted California Corporate Security Laws . Oliver was jailed for a short time, then placed on two years probation, but his plans proceeded no further. The device he had built near Whitewater became

2457-452: The facilities to begin construction by September 2011. The proposed project would replace the 460 existing wind turbines with 30 new turbines in two phases. Phase 1 would remove approximately 74 non-operational turbines and install up to fifteen new 1.5 MW GE SLE wind turbines. Phase 2 would remove approximately 384 Vestas V15 65kW turbines and install an additional fifteen 1.5 MW GE SLE wind turbines. The proposed project would therefore comprise

2520-741: The first windfarm in Southeast Asia. Located in the northern part of the country's biggest island, Luzon, alongside the seashore of Bangui , Ilocos Norte . The wind farm uses 20 units of 70-metre (230 ft) high Vestas V82 1.65 MW wind turbines, arranged on a single row stretching along a nine-kilometre shoreline off Bangui Bay, facing the South China Sea . Phase I of the NorthWind power project in Bangui Bay consists of 15 wind turbines, each capable of producing electricity up to

2646-516: The installed capacity, from wind energy, from 280 MW in 2010 to 2000 MW in 2020. Pakistan has wind corridors in Jhimpir, Gharo and Keti Bundar in Sindh province and is currently developing wind power plants in Jhimpir and Mirpur Sakro (District Thatta). The government of Pakistan decided to develop wind power energy sources due to problems supplying energy to the southern coastal regions of Sindh and Balochistan. The Zorlu Energy Putin Power Plant

2709-539: The largest operational onshore wind farms are located in China, India, and the United States. For example, the largest wind farm in the world , Gansu Wind Farm in China had a capacity of over 6,000  MW by 2012, with a goal of 20,000 MW by 2020. As of December 2020, the 1218 MW Hornsea Wind Farm in the UK is the largest offshore wind farm in the world . Individual wind turbine designs continue to increase in power , resulting in fewer turbines being needed for

2772-509: The local area, or connect to the Stage 2 to Martinborough 33 kV lines through a 750 kVA transformer to the north side of the stage. During peak demand, electricity generated by Hau Nui is used by Martinborough and the eastern South Wairarapa district. During off-peak, Hau Nui electricity can supply the entire South Wairarapa district via 33 kV lines connecting Martinborough with Featherston , Greytown , and Pirinoa . If local demand

2835-445: The most resource and opportunity are eventually developed. After the deadline to request a place in the queue has passed, many firms will withdraw their requests after gauging the competition in order to make back some of the deposit for each request that is determined too risky in comparison to other larger firms' requests. A major factor in wind-farm design is the spacing between the turbines, both laterally and axially (with respect to

2898-542: The pass on the northern edge of San Jacinto Peak. These lines effectively link the Los Angeles metropolitan area with the Palo Verde Nuclear Power Plant in Arizona. A single 500 kV line was upgraded to two lines in 2013, known as Devers-Palo Verde 2 (DPV2). The existing 220 kV transmission line heading west was doubled in 2021. Dew R. Oliver, president of the Oliver Electric Power Corporation,

2961-409: The prevailing winds). The closer the turbines are together, the more the upwind turbines block wind from their rear neighbors (wake effect). However, spacing turbines far apart increases the costs of roads and power cables, and raises the amount of land needed to install a specific capacity of turbines. As a result of these factors, turbine spacing varies by site. Generally speaking, manufacturers require

3024-599: The renewable energy sector. In 2011 the European Union had a total installed wind capacity of 93,957 MW. Germany had the third-largest capacity in the world (after China and the United States), with an installed capacity of 29,060 MW at the end of 2011. Spain had 21,674 MW, and Italy and France each had between 6,000 and 7,000 MW. By January 2014, the UK installed capacity was 10,495 MW. But energy production can be different from capacity – in 2010, Spain had

3087-460: The same total output. Because they require no fuel, wind farms have less impact on the environment than many other forms of power generation and are often referred to as a good source of green energy . Wind farms have, however, been criticised for their visual impact and impact on the landscape. Typically they need to be spread over more land than other power stations and need to be built in wild and rural areas, which can lead to "industrialization of

3150-589: The southern North Sea to England and the Celtic Sea to Ireland, and further south to France and Spain especially in Higueruela which was for some time the biggest wind farm in the world. The idea is that by the time a low pressure area has moved away from Denmark to the Baltic Sea the next low appears off the coast of Ireland. Therefore, while it is true that the wind is not blowing everywhere all of

3213-410: The surface and is affected by topography, surface roughness, and upwind obstacles such as trees or buildings. At altitudes of thousands of feet/hundreds of metres above sea level, the power in the wind decreases proportional to the decrease in air density. Often in heavily saturated energy markets, the first step in site selection for large-scale wind projects, before wind resource data collection,

3276-686: The time, it will tend to be blowing somewhere. In July 2022, Seagreen , the world's deepest fixed-bottom wind farm, became operative. Located 26 miles off the Angus coastline, in Scotland, it has 114 turbines that generate 1.1 gigawatts (GW) of electricity. India has the fifth largest installed wind power capacity in the world. As of 31 March 2014, the installed capacity of wind power was 21136.3 MW mainly spread across Tamil Nadu state (7253 MW). Wind power accounts nearly 8.5% of India's total installed power generation capacity, and it generates 1.6% of

3339-729: The total capacity to 33 MW. All 20 turbines describes a graceful arc reflecting the shoreline of Bangui Bay. Adjacent municipalities of Burgos and Pagudpud followed with 50 and 27 wind turbines with a capacity of 3 MW each for a Total of 150 MW and 81 MW respectively. Two other wind farms were built outside of Ilocos Norte, the Pililla Wind Farm in Rizal and the Mindoro Wind Farm near Puerto Galera in Oriental Mindoro . Sri Lanka has received funding from

3402-612: The wind accelerates over a ridge. The additional wind speeds gained in this way can increase energy produced because more wind goes through the turbines. The exact position of each turbine matters, because a difference of 30 metres could potentially double output. This careful placement is referred to as 'micro-siting'. Europe is the leader in offshore wind energy, with the first offshore wind farm (Vindeby) being installed in Denmark in 1991. As of 2010, there were 39 offshore wind farms in waters off Belgium, Denmark, Finland, Germany, Ireland,

3465-457: The wind turbines. Therefore, special fast service vehicles for installation (like Wind Turbine Shuttle) as well as for maintenance (including heave compensation and heave compensated working platforms to allow the service staff to enter the wind turbine also at difficult weather conditions) are required. So-called inertial and optical based Ship Stabilization and Motion Control systems (iSSMC) are used for that. Experimental wind farms consisting of

3528-541: The world at 659 MW , followed by the London Array (630 MW) also in the UK. Offshore wind turbines are less obtrusive than turbines on land, as their apparent size and noise is mitigated by distance. Because water has less surface roughness than land (especially deeper water), the average wind speed is usually considerably higher over open water. Capacity factors (utilisation rates) are considerably higher than for onshore locations. The province of Ontario, Canada
