SC Energy Data

Generation

Generation is the amount of electricity produced over a specific period of time, measured in watt-hours (Wh). For example, a generator with 1 MW (1 million watts) capacity that operates at that capacity consistently for one hour will produce 1 MWh of electricity.
 
Electricity generated in South Carolina is not necessarily consumed in the state. South Carolina has two multi-state utilities (Duke Energy Carolinas and Duke Energy Progress) that share the electricity generated in both South Carolina and North Carolina among their customers in the Carolinas. Therefore, the generation fuel mix does not solely represent the consumption by South Carolina customers, due to electric resources being shared across both states. The pro rata share data represents the portion of electricity consumed in South Carolina.
