The Tehachapi Pass wind farm is one of the first large-scale wind farms installed in the U.S., with around 710 megawatts (950,000 hp) produced by about 3400 wind turbines.
Wind power in Texas, a portion of total energy in Texas, consists of over 150 wind farms, which together have a total nameplate capacity of over 30,000 MW. If Texas were a country, it would rank fifth in the world: The installed wind capacity in Texas exceeds installed wind capacity in all countries but China, the United States, Germany and India. Texas produces the most wind power of any U.S. state. According to the Electric Reliability Council of Texas (ERCOT), wind power accounted for at least 15.7% of the electricity generated in Texas during 2017, as wind was 17.4% of electricity generated in ERCOT, which manages 90% of Texas's power. ERCOT set a new wind output record of nearly 19.7 GW at 7:19 pm Central Standard Time on Monday, January 21, 2019.
The Roscoe Wind Farm near Roscoe, Texas is one of the world's largest-capacity wind farms. With 627 wind turbines and a total installed capacity of 781.5 MW, owned and operated by RWE. At the time of its completion in 2009, it was the largest wind farm in the world, surpassing the nearby 735.5-megawatt Horse Hollow Wind Energy Center. In 2012, it was overtaken by California's 1,020-megawatt Alta Wind Energy Center.
Wind power in Ohio has a long history, and as of 2016, Ohio had 545 megawatts (MW) of utility-scale wind power installations installed, responsible for 1.1% of in-state electricity generated. Over 1000 MW more were under construction or pending approval. Some installations have become tourist attractions. There has been a sudden increase in generating capacity, as total wind power capacity in the state was just 9.7 MW in 2010. By 2019, there were 738 MW of capacity, which generated 1.71% of Ohio's electricity.
The Cedar Creek Wind Farm is a 551.3 megawatt (MW) wind farm located about 8 miles east of the town of Grover in north-central Weld County, Colorado. It consists of 397 wind turbines and was constructed in two phases, Cedar Creek I and Cedar Creek II, becoming fully operational in 2010. The electricity is sold to the Public Service Company of Colorado.
The Capricorn Ridge Wind Farm is located in Sterling and Coke counties, Texas. It is a 662.5 MW wind farm, with 342 GE 1.5 MW wind turbines and 65 2.3 MW Siemens turbines that are capable of generating enough electricity for more than 220,000 homes. The wind farm is built, owned and operated by a subsidiary of NextEra Energy Resources, the U.S.' largest wind energy generator. The project is part owned by San Antonio-based Sullivan Trillian Fund Private Equity.
The 605.2 megawatt (MW) Peñascal Wind Farm project is located south of Baffin Bay in Kenedy County, Texas and was constructed in three phases by Iberdrola and Mortenson Construction. It became Iberdrola's largest renewable energy facility in the world after completion of the second phase in 2010.
The Panther Creek Wind Farm in Big Spring, Texas, United States consists of 305 wind turbines and has an installed capacity of 457.5 megawatts, making it one of the ten largest wind farms in the United States. Phases I and II of the wind farm became operational early in 2009, with the completion of the third and final phase in September 2009. The projects are located in Howard, Sterling and Glasscock Counties. The wind farm can now generate enough wind power to supply 135,000 Texan homes.
Alta Wind Energy Center (AWEC), also known as Mojave Wind Farm, is the third largest onshore wind energy project in the world. The Alta Wind Energy Center is a wind farm located in Tehachapi Pass of the Tehachapi Mountains, in Kern County, California. As of 2022, it is the largest wind farm in the United States, with a combined installed capacity of 1,550 MW (2,080,000 hp). The project, being developed near Tehachapi Pass Wind Farm— site of the first large-scale wind farms installed in the U.S. in the 1970s and 1980s—is "a powerful illustration of the growing size and scope of modern wind projects".
Coal Clough Wind Farm is one of the oldest onshore wind farms in England. The wind farm, which was built for Scottish Power, produced electricity from originally 24 Vestas WD34 wind turbines. It had a total nameplate capacity of 9.6 MW of electricity, enough to serve the average needs of 5,500 homes. It is situated near Burnley, Lancashire in the parish of Cliviger, near Coal Clough Farm, on the edge of Stiperden Moor in the South Pennines. For a few weeks it was the largest wind farm in the UK, until the much larger Penrhyddlan and Llidiartywaun wind farms in Powys, Wales overtook it. It narrowly remained the largest in England until Coldham opened in Cambridgeshire in November 2005. The record was then taken yet again by Scout Moor Wind Farm 7 miles (11 km) to the south west until May 2009 where Whitelee Wind Farm took and now holds it with 215 units with a total output capacity of 539 Mw. In 2009 Scottish Power announced plans to replace the existing turbines with eight 2 MW units with an estimated maximum height 110 metres (361 ft).
Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely. There are many upsides to repowering.
The US state of Colorado has vast wind energy resources and the installed electricity capacity and generation from wind power in Colorado has been growing significantly in recent years. The growth has been sustained due to a combination of falling costs, continuing federal incentives, and the state's aggressive renewable portfolio standard that requires 30% of the state's electricity to come from renewable sources by 2020.
The Papalote Creek Wind Farm near Taft, Texas in San Patricio County is an array of 196 wind turbines that can produce 380 megawatts (MW) of power, enough to serve approximately 114,000 homes. The wind farm was built and is operated by E.ON Climate and Renewables North America.
The U.S. State of Oklahoma has high potential capacity for wind power in the western half of the state. In 2017, Oklahoma's installed wind generation capacity was almost 7,500 megawatts, supplying almost a third of the state's generated electricity.
Wind power in Hawaii has the potential to provide all of the electricity generation in the electricity sector in Hawaii. The 132 commercial wind turbines in the state have a total capacity of 236 MW. In 2015, wind turbines produced 6.4% of Hawaii's electricity. In 2012, Hawaii generated 367 million kWh from wind power.
Wind power in Missouri has an installed capacity of 959 MW from 499 turbines, as of 2016. This provided 1.29% of the state's electricity production.
Los Vientos Wind Farm is a 912 megawatt (MW) wind farm in Starr and Willacy counties in South Texas. It is the second largest wind farm in the United States behind the Alta Wind Energy Center in California.
