Entergy Corp. said it expects second-quarter earnings to be about $1.04 per share and operational earnings of about $1.10 per share, up from second-quarter 2013 earnings of 92 cents per share on an as-reported basis and $1.01 per share on an operational basis.

The New Orleans-based power company attributed the gain in part to higher volume and prices in its wholesale generation business.

Entergy also affirmed its 2014 operational earnings guidance range of $5.55 to $6.75 per share.

Entergy will report second-quarter earnings before the stock market opens on July 29.
