RICHMOND, Va. (AP) — Energy provider Dominion Resources Inc. said Wednesday that costs related to summer storm outages and other charges, as well as declines in electricity use due to milder-than-normal weather, drove its second-quarter profit down about 23 percent.

The Richmond, Va.-based company reported earnings of $258 million, or 45 cents per share for the three months ended June 30, compared with $336 million, or 58 cents per share, a year ago.
