The July 23 announcement of a guilty plea by former SCANA executive Stephen A. Byrne to federal charges of mail and wire fraud related to the failed V.C. Summer nuclear expansion project—along with a pledge to cooperate with federal authorities—sets up a possible day of reckoning for the South Carolina utility’s former CEO Kevin B. Marsh.
Marsh is a co-defendant in the case who still faces charges and Byrne's plea and cooperation could strengthen the case against the chief executive.
