Spanish Company to Buy C.M.P. 

The Iberdrola Corporation plans to buy Energy East, which owns Central Maine Power.

The $4,500,000,000 deal is expected to close next year.

Before that happens though, the deal has to be approved by federal and state regulators, as well as shareholders.

Governor Baldacci says he’s cautiously optimistic about the deal, based on what he’s learned so far from C.M.P. officials.
