S.C. regulatory staff recommends approval of line needed to connect new nuclear unit

The South Carolina Office of Regulatory Staff (ORS) and South Carolina Electric & Gas (SCE&G) are jointly recommending that the Public Service Commission of South Carolina (PSC) approve a certificate of environmental compatibility and public convenience and necessity (CECPCN) for the construction and operation of two 230-kV transmission lines and associated facilities (Docket No. 2012-225-E).

The project will connect unit 3 of the V.C. Summer nuclear station in Jenkinsville, S.C., to the parts of SCE&G’s grid that serve the Charleston area load centers and other load centers in the South Carolina lowcountry, a spokesperson for the utility told TransmissionHub Sept. 4.

SCE&G is adding two new generating units to the V.C. Summer station. Units 2 and 3 are both under construction and are expected to come on line in 2017 and 2018, respectively.

The recommended approval of the transmission project is contained in a joint proposed order submitted to the PSC on Aug. 30. That order notes that a new switchyard and substation will also be constructed as part of the project.

Transmission lines needed to connect unit 2 to the grid were previously approved by the PSC and are under construction, the spokesperson said. A total of 250 miles of new lines will serve the two new generating units.

The commission has not set a date for a ruling on the matter but anticipates a ruling some time this month, a PSC spokesperson told TransmissionHub on Sept. 4.
