On March 27, 2008, South Carolina Electric & Gas applied to the Nuclear Regulatory Commission (NRC) for a Combined Construction and Operating License (COL) to build two 1,100 MW AP1000 pressurized water reactors at the site. On May 27, 2008, SCE&G and Santee Cooper announced an engineering, procurement and construction (EPC) contract had been reached with Westinghouse. Costs were estimated to be approximately $9.8 billion for both AP1000 units, plus transmission facility and financing costs. The operators are filing an application to increase customers bills by $1.2 billion (2.5%) during the construction period to partially finance capital costs.
