Power company: SC nuke reactors will cost more, be finished later due to construction delays

The company that owns a majority stake in new nuclear reactors in South Carolina wants approval to spend more on the project and finish construction later than expected.

SCANA Corp. CEO Kevin Marsh said Friday he's asked for a hearing before state regulators regarding the V.C. Summer Nuclear Station near Jenkinsville, about 25 miles northwest of Columbia.

Marsh says SCANA and its electric utility component, SCE&G, originally anticipated that it would need to spend around $660 million due to construction delays. Now, Marsh says that number is around $698 million.

SCANA is required to update the Public Service Commission whenever it may miss a major construction milestone by more than 18 months. The company says it anticipates the units will come online in 2019 and 2020.
