Allegheny Power System Inc. will merge with DQE Inc., parent company of Duquesne Light Co., to form Allegheny Energy, which will save both companies about $1 billion over the next 10 years.
The new company will have a total market capitalization of $10.6 billion: $6.2 billion in equity and $4.4 billion in net debt and preferred stock.
"Allegheny Power is a winter-peaking operation: Its low-cost, efficient operations and suburban and rural customer mix fit well with our summer-peaking operation and urban customer base," said David Marshall, President and CEO of DQE.
