SCANA stockholders on Tuesday overwhelmingly approved the company’s sale to Dominion Energy, moving the deal one step closer to completion.

FERC authorized Dominion Energy’s proposed acquisition of SCANA and its South Carolina Electric & Gas subsidiary.

South Carolina legislators continue to maneuver as if there is some room to negotiate the terms of a deal to sell SCANA to Dominion, but Dominion CEO Thomas Farrell emphatically rejected that presumption on a conference call to discuss the company’s Q1 2018 earnings.

Dominion Energy said it will buy SCANA for $7.9 billion in a stock-for-stock transaction, securing a utility troubled by a botched nuclear project.
