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 for thirty years the world's largest solar thermal energy generating facility, until the commissioning of the even larger Ivanpah facility in 2014. It was also for thirty years the world's largest solar generating facility of any type of technology, until the commissioning of the photovoltaic Topaz Solar Farm 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.
The William H. Zimmer Power Station, located near Moscow, Ohio, was a 1.35-gigawatt coal power plant. Planned by Cincinnati Gas and Electric (CG&E), with Columbus & Southern Ohio Electric and Dayton Power & Light (DP&L) as its partners, it was originally intended to be a nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. The plant began operations in 1991. Vistra Corp. acquired ownership in 2018 and operated the plant until its closure on May 31, 2022.
A gas-fired power plant, sometimes referred to as gas-fired power station, natural gas power plant, or methane gas power plant, is a thermal power station that burns natural gas to generate electricity. Gas-fired power plants generate almost a quarter of world electricity and are significant sources of greenhouse gas emissions. However, they can provide seasonal, dispatchable energy generation to compensate for variable renewable energy deficits, where hydropower or interconnectors are not available. In the early 2020s batteries became competitive with gas peaker plants.
The Dickerson Generating Station is an 853 MW electric generating plant owned by NRG Energy, located approximately two miles west of Dickerson, Maryland, on the eastern banks of the Potomac River.
Edgewater Generating Station is a 380 megawatt (MW) coal power plant located on the south side of Sheboygan, Wisconsin, on the shore of Lake Michigan, whose waters are used to provide cooling. It provides electricity for customers in the northeastern part of Alliant Energy's Wisconsin Power & Light service area and service to several local municipal utilities. In 2009, it was the seventh largest generating station in Wisconsin, with a net summer capacity of 767 MW.
Shale gas in the United States is an available source of unconventional natural gas. Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of U.S. natural gas. Largely due to shale gas discoveries, estimated reserves of natural gas in the United States in 2008 were 35% higher than in 2006.
The Utica Shale is a stratigraphical unit of Upper Ordovician age in the Appalachian Basin. It underlies much of the northeastern United States and adjacent parts of Canada.
The energy sector of Ohio consists of thousands of companies and cities representing the oil, natural gas, coal, solar, wind energy, fuel cell, biofuel, geothermal, hydroelectric, and other related industries. Oil and natural gas accounts for $3.1 billion annually in sales while ethanol generates $750 million. Toledo is a national hub in solar cell manufacturing, and the state has significant production of fuel cells. In 2008, the state led the country in alternative energy manufacturing according to Site Selection Magazine, while the natural gas industry has experienced growth due to the expansion of shale gas.
Caithness Energy, LLC is an independent power producer in the United States. Some of its planned, current, and former facilities include:
Bethpage Energy Center is a power station in Bethpage, New York, United States, consisting of two combined cycle plants opened in 1989 and 2005, and one gas turbine peaking plant opened in 2002. The original plant was commissioned by Grumman Aerospace for its Bethpage complex because it was deemed more cost-effective than purchasing power from electric utilities. It was acquired by Calpine in 1998, which expanded the facility with two more plants.
