The company will construct about 250 miles of new 230kV transmission lines associated with the expansion of the VC Summer nuclear station in South Carolina.

These lines will support two nuclear power units being added by South Carolina Electric & Gas, the principal subsidiary of Scana, and the South Carolina Public Service Authority (Santee Cooper), a state-owned electric and water utility in South Carolina.

The new nuclear units, known as VC Summer 2 and 3, are expected to be completed in 2016 and 2019.

Scana is principally engaged, through subsidiaries, in electric and natural gas utility operations and other energy-related businesses in South Carolina, North Carolina and Georgia.
