Since the formation of Oglethorpe Power Corporation (OPC) in 1974, the corporation’s Member Systems have experienced nearly continuous growth in their need for power. In 1975, the Members had a combined peak demand for power of 1,361 megawatts (MW). In January 2014, that number reached an all-time high of 9,354 MW. In terms of energy use, the Member Systems required 39,668,000 megawatt-hours (MWh) of electric energy in 2016. Of the total , Oglethorpe Power supplied 25,522,852 MWh of the energy the Member Systems required in 2016, or about 64 percent. The EMCs secure the remainder of their power needs from various other power providers. Oglethorpe provides energy to its Member Systems with a diverse energy portfolio of owned or managed facilities that include natural gas, hydroelectric, coal and nuclear generating plants with a combined capacity of nearly 7,810 megawatts (total indicative Summer 2017 planning reserve capacity).
A megawatt equals one thousand kilowatts.
“Peak demand” occurs when consumers are using the most electricity — usually hot summer afternoons.
About 64 percent of Member EMCs' energy needs in 2016 were supplied by OPC.
