Oglethorpe Power Corporation is a medium-sized electric utility in Georgia, United States. Formed in 1974, Ogelthorpe is a not-for-profit cooperative owned by the 38 electric membership corporations that it serves. The utility's headquarters are in Tucker, Georgia.
In 1935, the Rural Electrification Administration (REA) provided loans for building transmission lines in rural areas, and EMCs were created in Georgia to purchase power from various sources. In 1974, 39 Georgia-based EMCs incorporated Oglethorpe Power Corporation to invest in generating capacities and transmission lines.
In 1996, Oglethorpe Power signed a 15-year, $4-5 billion deal with LG&E to receive half of its electricity needs from the Kentucky-based power supplier, with a locked down price on the coal-fired megawatt that LG&E must maintain.
In 1997, Ogelthorpe restructured into three separate, but interrelated, cooperatives. Oglethorpe Power Corporation handles electricity generation, Georgia Transmission Corporation owns and operates the transmission lines and substations and Georgia System Operations Corporation provides system and administrative support.
In September 2008, Oglethorpe Power announced the construction of a massive woody biomass power plant (two 100-megawatt-per-year, carbon-neutral facilities) to power nearly half of Georgia's population.
In 2017, the turmoil surrounding the failed deliveries of nuclear reactors by bankrupted Westinghouse put Oglethorpe Power at the forefront of the country's nuclear crisis.
Oglethorpe Power is the largest power supply cooperative in the United States based upon assets and annual kilowatt-hour sales. The utility's service area covers 65 percent of the state of Georgia. Ogelthorpe co-own several of its plants with Georgia Power (largest electricity supplier in the state) and the Municipal Electric Authority of Georgia.
