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, [1] 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". [2] [3]

Southern California Edison has agreed to a 25-year power purchase agreement for the power produced as part of the power purchase agreements for up to 1500 MW or more of power generated from new projects to be built in the Tehachapi area. The project will "reduce carbon dioxide emissions by more than 5.2 million metric tons, which is equivalent to taking 446,000 cars off the road". [2] A total of 3000 MW is planned. [4]

The wind farm was developed by Terra-Gen Power which closed a US$1.2 billion financing deal in July 2010 with partners that included Citibank, Barclays Capital, and Credit Suisse. After many delays, the first phase began construction in 2010. Financing for additional phases of $650 million was secured in April 2012. Construction of the Alta Wind Energy Center is expected to create more than 3,000 domestic manufacturing, construction, and maintenance jobs, and contribute more than one billion dollars to the local economy.

The original "Alta-Oak Creek Mojave Project" plan consisted of up to 320  wind turbines occupying a 9,000-acre (36 km2) area while producing 800 MW of power. That project was originally developed by Oak Creek Energy Systems under the contract with Terra-Gen, but the project development was later transferred to Terra-Gen. The project then became the first development under the umbrella of Alta Wind Energy Center. [5]

The Alta-Oak Creek Mojave Project is generally located at the south side of the Oak Creek Road, starting a few miles west of the state route 14 in Mojave and continuing westward along the Oak Creek Road to the west side of the Tehachapi-Willow Springs Road. [6]

According to the American Wind Energy Association, two initial projects were completed in fall 2010, the 150 MW Alta II (Vestas) project using 50 3 MW generators and the 150 MW Alta I project using 100 1.5 MW generators. [7] Three subsequent projects 150 MW Alta III, 102 MW Alta IV, and 168 MW Alta V projects were completed in the 2nd quarter of 2011 using 50, 34, and 56 3 MW Vestas V-90 wind turbines. Alta VIII and Alta VI projects, comprising 300 MW, were completed in late 2011/early 2012, but they were renamed Brookfield Tehachapi 2 and Mustang Hills respectively. Alta VII and IX projects comprising 300 MW, were completed in December 2012 (bringing the total to 1320 MW), but they were renamed to Pinyon Pines Wind I and Pinyon Pines Wind II. [8]

138 MW Alta X and 90 MW Alta XI are under development with scheduled completion in late 2013, 180 MW Alta XIII in 2019. [9]

The Altamont Pass wind farm is located in the Altamont Pass of the Diablo Range in Northern California. It is one of the earliest wind farms in the United States. The first wind turbines were placed on the Altamont in the early 1980s by Fayette Manufacturing Corporation on land owned by cattle rancher Joe Jess. The wind farm is composed of 4930 relatively small wind turbines of various types, making it at one time the largest wind farm in the world in terms of capacity. Altamont Pass is still one of the largest concentration of wind turbines in the world, with a capacity of 576 megawatts (MW), producing about 125 MW on average and 1.1 terawatt-hours (TWh) yearly. They were installed after the 1970s energy crisis in response to favorable tax policies for investors.

<span class="mw-page-title-main">Wind power in California</span> Electricity from large wind farms

Wind power in California had initiative and early development during Governor Jerry Brown's first two terms in the late 1970s and early 1980s. The state's wind power capacity has grown by nearly 350% since 2001, when it was less than 1,700 MW. In 2016, wind energy supplied about 6.9% of California's total electricity needs, or enough to power more than 1.3 million households. Most of California's wind generation is found in the Tehachapi area of Kern County, California, with some large projects in Solano, Contra Costa and Riverside counties as well. California is among the states with the largest amount of installed wind power capacity. In recent years, California has lagged behind other states when it comes to the installation of wind power. It was ranked 4th overall for wind power electrical generation at the end of 2016 behind Texas, Iowa, and Oklahoma. As of 2019, California had 5,973 megawatts (MW) of wind power generating capacity installed.

The Milford Wind Corridor Project, also called Milford Wind, is a 306 megawatt (MW) wind farm spanning Beaver and Millard County north of Milford, Utah. It became the state's largest wind facility when the first phase was completed in 2009. The electricity is being sold to the Southern California Public Power Authority.

<span class="mw-page-title-main">Wind power in Wyoming</span> Electricity from wind in U.S. state

Wyoming has one of the highest wind power potentials of any state in the United States. In 2019, Wyoming had wind powered electricity generating capacity of 1,589 MW, which produced 9.85% of its electric generation, with an additional 3,753 MW under construction. However, the wind generation in that year was Wyoming's third-lowest in the 2010s. By 2020, wind capacity increased to 2738 MW and 8448 gigawatt-hours of electricity were produced from wind in 2021, more than double 2019 production. Additional wind capacity and needed transmission lines are under construction or planned, despite political headwinds from Wyoming's strong coal and oil sectors.

<span class="mw-page-title-main">Wind power in Minnesota</span> Electricity from wind in one U.S. state

At the end of 2016, the installed capacity for wind power in Minnesota was 3,500 megawatts (MW). Wind power generated nearly 18 percent of Minnesota’s electricity in 2016, ranking sixth in the nation for wind energy as a share of total electricity generation.
