“We expect 2010 to be another demanding year for our company and our industry,” said Anthony J. Alexander, president and chief executive officer.  “And, while we are pleased that we met our first quarter earnings target, we are staying focused on the fundamentals and continue taking steps to address the economy and other challenges.  We remain committed to successfully executing our strategy and meeting the expectations of our shareholders and customers.”
 
 First quarter 2010 results benefited from cost control initiatives implemented last year including lower labor and employee benefits expenses, the net impact of Ohio rate changes, and lower taxes.  Results were negatively affected by lower commodity margin, reduced transition cost recovery by Cleveland Electric Illuminating Co., and higher depreciation expenses and financing costs.
 
 Consolidated electric generation sales in the first quarter of 2010 were down 8 percent compared with 2009.  Sales in the retail market were down 1 percent, while sales in the wholesale market decreased 37 percent.
 
 Total distribution deliveries in the first quarter increased slightly compared to 2009, as a 7 percent increase in usage from industrial customers – primarily in the steel and automotive sectors – more than offset the reduction in sales to residential and commercial customers that resulted from milder temperatures across much of the company’s service area.
 
 FirstEnergy today also affirmed its 2010 earnings guidance of $3.50 to $3.70 per share of common stock on a non-GAAP basis.
