FirstEnergy has acquired Allegheny Energy for $4.7 billion in a deal that would create one of the largest utility groups in the US. The combined company would have 10 regulated power utilities across seven states, including New York, Ohio, Pennsylvania, Maryland, New Jersey, Virginia and West Virginia. It would have a total 24,000 megawatts of generating capacity from coal, nuclear, natural gas, oil and renewable power. The new company would retain the FirstEnergy name and be based in Akron, Ohio.
