Santee Cooper plans $135-million transmission expansion

State-owned utility will pay for new power lines by selling bonds

Charleston, S.C.-based Santee Cooper recently announces its plans to build $135 million worth of high-voltage power lines over the next three years. The utility will string almost 200 miles of transmission lines.

About $50 million of that infrastructure will be used to connect two power turbines at its Cross generating station to the rest of the grid.
