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 38,323,141 megawatt-hours (MWh) of electric energy in 2015. Of the total , Oglethorpe Power supplied 18,371,558 MWh of the energy the Member Systems required in 2015, or about 48 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 7,785 megawatts (summer peak capacity).
A megawatt equals one thousand kilowatts.
“Peak demand” occurs when consumers are using the most electricity — usually hot summer afternoons.
About 48 percent of Member EMCs' energy needs in 2015 were supplied by OPC.
