COLUMBIA, S.C. (AP) — South Carolina's utility watchdog agency wants to know how much SCANA Corp. and its proposed suitor, Virginia-based Dominion Energy, are spending on lobbying and advertising.

The Post and Courier of Charleston reported South Carolina's Office of Regulatory Staff raised the questions as state lawmakers consider whether to go along with the $14.6 billion sale.

SCANA's South Carolina Electric and Gas Co. and the state-owned utility Santee Cooper walked away from construction of two nuclear reactors last July.

State lawmakers appear to be wary of the deal, wondering if the South Carolina utility can find a better offer.

SCE&G and Santee Cooper mostly blamed the bankruptcy of lead contractor Westinghouse for the failure of the project that had already cost more than $9 billion and was behind scheduled and over budget.
