In what it called a "ground breaking" deal, PPL Corp., Allentown, Pa., has agreed with a coalition of government agencies and private groups to remove or close down three hydroelectric plants totaling 18 Mw on the Penobscot River north of Bangor, Maine.
In return, the coalition will support relicensing six existing PPL dams farther upstream totaling 27 Mw as well as a PPL plan to add more capacity at the six dams to recover up to a 90% of the lost generating capacity downstream.
