Older wind turbines

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. [1] The wind farm is composed of 4,930 [2] relatively small wind turbines of various types, making it at one time the largest wind farm in the world in terms of capacity.

Contents

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. [3] They were installed after the 1970s energy crisis in response to favorable tax policies for investors.

In the media

When the first windfarms appeared in 1981, on the Altamont hills alongside the Altamont Pass portion of the I-580 freeway, the appearance of the modern windmill generated media excitement and public interest. This portion of the freeway was an increasingly used corridor for growing the bedroom communities of Tracy, Lodi and Modesto serving the Bay Area of California (Oakland, San Francisco and Pleasanton). Daily commuters crowded past the otherwise barren cattle ranches for several hours each day.

By 1985, the Altamont Pass was crowded with over 26 different windfarms. The increased visibility from the nearby I-580 freeway, which had once sparked the media and community's interest, was now widely regarded as a growing eyesore. Successful windfarms at the Altamont Pass encouraged the development of further industrial wind areas in southern California. These windfarms, in the Tehachapi Pass, led to wider recognition, after windmills played a role as a prominent backdrop in several feature films of the mid- and late 1980s, including the 1985 film based on the Bret Easton Ellis novel Less than Zero , featuring Andrew McCarthy and Robert Downey, Jr.

Environmental effects

The small turbines used at Altamont are dangerous to various raptors that hunt California ground squirrels in the area. 1,300 raptors are killed annually, among them 70 golden eagles, which are federally protected. In total, 4,700 birds are killed annually [4] including the endangered California condor. [5] Overall there has been an 80% decline in golden eagles in Northern California, with no golden eagles nesting near the facility, although it is a prime habitat. [6]

Considered largely obsolete, these numerous small turbines are being gradually replaced with much larger and more cost-effective units. The larger units rotate at a much lower angular frequency to the previous turbines, and, being elevated higher, are claimed to be less hazardous to the local wildlife. This claim is supported by a report done for the Bonneville Power Administration. [7]

As of 2010, a settlement has been reached between the Audubon Society, Californians for Renewable Energy and NextEra Energy Resources, who operate some 5,000 turbines in the area. Nearly half of the smaller turbines will be replaced by newer, more bird-friendly models. The project was expected to be complete by 2015 and included $2.5 million for raptor habitat restoration. [8]

Wind farms

The Altamont Pass Wind Farm [9] is now composed of five constituent wind farms. The Golden Hills Wind Farm is the largest constituent wind farm, as well as being the only one located south of Altamont Pass.

Repowering

In 2015, NextEra – which owns some of the 100kW Kenetech/US Windpower older turbines installed during the 1980s – agreed to remove the machines and replace them with 48 new model wind turbines. A power purchase agreement has been completed to power the Googleplex office complex in nearby Mountain View, California. The process of removing old wind turbines and replacing them with newer machines is called repowering. [15]

A portion of the wind energy center is being dismantled as of 2016. Altamont Winds Inc (AWI)'s 83MW of 100 kW Kenetech turbines are being taken down. These are older models with lattice towers. It has been proposed to replace them with 27 turbines with rated capacity of 2.1MW each (56.7MW total). [16]

The Scott Haggerty wind farm replaced 569 100-kW turbines with 23 modern turbines in 2021. [17]

Solar Energy Generating Systems (SEGS) is a concentrated solar power plant in California, United States. With the combined capacity from three separate locations at 354 megawatt (MW), it was once the world's second largest solar thermal energy generating facility, until the commissioning of the even larger Ivanpah facility in 2014. It consisted of nine solar power plants in California's Mojave Desert, where insolation is among the best available in the United States.

<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.

<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.

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".
