Duke Energy, the state's biggest electric company, reported a second-quarter loss this morning despite a boost in revenue.
The Charlotte-based utility, with 1.8 million customers in this state, lost $222 million for the quarter ending June 30, compared to profits of $276 million during the same three-month period a year ago.
The reason for the loss was a depreciation in the value of the company's power plants in the Midwest. Duke sells electricity in three Midwestern states as well as in the Carolinas.

Progress Energy, based in Raleigh, reports second quarter earnings on Thursday morning.
