Sources of Utah electricity generation: full-year 2023 [1]
This is a list of electricity-generating power stations in the U.S. state of Utah , sorted by type and name. In 2022, Utah had a total summer capacity of 9,627 MW through all of its power plants, and a net generation of 39,386 GWh. [2] In 2023, the electrical energy generation mix was 47.2% coal, 35.4% natural gas, 11.6% solar, 2% wind, 1.6% hydroelectric, 1.5% geothermal, 0.2% biomass, 0.1% petroleum, and 0.3% other. [1]
Small-scale solar including customer-owned photovoltaic panels delivered an additional net 906 GWh to Utah's electricity grid in 2023. This compares as less than one-fourth the amount generated by Utah's utility-scale PV plants. [1] Coal previously generated 81% of Utah's electricity in 2013 and has been undergoing a gradual replacement with natural gas and renewables. [3]

Although there are currently no nuclear power stations in Utah, the Blue Castle Project is working through the process of building the state's first nuclear power plant near Green River, Utah. It is projected to be completed in 2030. [70]
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind, the sun or hydro-electric installations. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production.
PacifiCorp is an electric power company in the western United States.
In Honduras, there is an important potential of untapped indigenous renewable energy resources. Due to the variability of high oil prices and declining renewable infrastructure costs, such resources could be developed at competitive prices.
Alterra Power Corp. a subsidiary of Innergex Renewable Energy Inc., is a diversified renewable power generation company based in Vancouver, British Columbia, Canada. It was formed in 2011 through the merger of Magma Energy Corp. and Plutonic Power Corp. It develops, owns, acquires and operates hydroelectric, wind, solar energy and geothermal projects. On February 6, 2018, Innergex Renewable Energy Inc. completed the acquisition of Alterra including all its assets.
Renewable energy in South Africa is energy generated in South Africa from renewable resources, those that naturally replenish themselves—such as sunlight, wind, tides, waves, rain, biomass, and geothermal heat. Renewable energy focuses on four core areas: electricity generation, air and water heating/cooling, transportation, and rural energy services. The energy sector in South Africa is an important component of global energy regimes due to the country's innovation and advances in renewable energy. South Africa's greenhouse gas (GHG) emissions is ranked as moderate and its per capita emission rate is higher than the global average. Energy demand within the country is expected to rise steadily and double by 2025.
California produces more renewable energy than any other state in the United States except Texas. In 2018, California ranked first in the nation as a producer of electricity from solar, geothermal, and biomass resources and fourth in the nation in conventional hydroelectric power generation. As of 2017, over half of the electricity (52.7%) produced was from renewable sources.
The Escalante Solar Project is a 240 MWAC (315 MWp) photovoltaic power station located about 5 miles north of the town of Milford in Beaver County, Utah. The project was developed by SunEdison, built by Mortenson Construction, and commissioned in September 2016. The power is being sold under three separate 20-year power purchase agreements to Rocky Mountain Power which serves customers in Utah, Idaho, and Wyoming. At 1900 acres (3.0 sq miles), it is the largest grouping of photovoltaic generators in the state of Utah.
The Enterprise Solar Farm is an 80 MWAC (105 MWp) photovoltaic power station located about 25 miles west of Cedar City, Utah in Iron County. The project was developed by SunEdison, built by Mortenson Construction, and commissioned in September 2016. The electricity is being sold under a 20-year power purchase agreement to Rocky Mountain Power which serves customers in Utah, Idaho, and Wyoming.
