Arizona electricity production by type

This is a list of electricity-generating power stations in the U.S. state of Arizona , sorted by type and name. In 2021, Arizona had a net summer capacity of 27,596 MW through all of its power plants, and a net generation of 109,305 GWh. [2] The electrical energy generation mix in 2023 was 47.3% natural gas, 28.2% nuclear, 10.8% coal, 6.6% solar, 5.3% hydroelectric, 1.6% wind, and 0.2% biomass. Small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 4,431 GWh to the state's electrical grid. This compares as about one-half the amount generated by Arizona's utility-scale solar plants. [1]

Arizona's Palo Verde Nuclear Generating Station located to the west of Phoenix is the nation's largest facility by annual energy production, and is the second largest facility by power capacity after Washington state's Grand Coulee Dam hydroelectric station. The electricity generated by utility- and small-scale solar together surpassed the amount from all of Arizona's hydroelectric facilities for the first time in 2017. [3]

A Generating capacity at Hoover Dam is equally split between Arizona and Nevada. [4] Its total capacity was derated to 1,596 MW in June 2014 due to persistently low water storage levels and projected further declines. [32] [33]

<span class="mw-page-title-main">Solana Generating Station</span> Solar thermal power station in Arizona

The Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix. It was completed in 2013. When commissioned, it was the largest parabolic trough plant in the world, and the first U.S. solar plant with molten salt thermal energy storage. Built by the Spanish company Abengoa Solar, the project can produce up to 280 megawatts (MW) gross, supplied by two 140 MW gross (125 MW net) steam turbine generators: enough electricity to meet the needs of approximately 70,000 homes and obviate the emission of roughly 475,000 tons of CO2 every year. Its name is the Spanish term for "sunny spot".

<span class="mw-page-title-main">Solar power in Arizona</span> Overview of solar power in the U.S. state of Arizona

Solar power in Arizona has the potential to, according to then-Governor Janet Napolitano, make Arizona "the Persian Gulf of solar energy". In 2012, Arizona had 1,106 MW of photovoltaic (PV) solar power systems, and 6 MW of concentrated solar power (CSP), bringing the total to over 1,112 megawatts (MW) of solar power. As an example, the Solana Generating Station, a 280 MW parabolic trough solar plant, when commissioned in 2013, was the largest parabolic trough plant in the world and the first U.S. solar plant with molten salt thermal energy storage.

<span class="mw-page-title-main">Battery storage power station</span> Energy storage system using electrochemical secondary cells

A battery storage power station, or battery energy storage system (BESS), is a type of energy storage power station that uses a group of batteries to store electrical energy. Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used to stabilise those grids, as battery storage can transition from standby to full power in under a second to deal with grid contingencies.
