The sale to the ArcLight affiliate involves five hydroelectric generating facilities in Maine that produce a total of 23MW of electricity and are 100% owned by PPL; and PPL's 50% ownership interest in a separate 13MW hydroelectric project, of which the other 50% is already owned by another ArcLight affiliate.

The $81 million excludes certain contingent consideration that will be realized upon completion of PPL's previously announced potential sale of three other hydroelectric facilities to the Penobscot River Restoration Trust.

William Spence, PPL's executive vice president and COO, said: "PPL believes strongly in this important project and remains fully committed to obtaining all approvals necessary to transfer these three facilities to the trust."
