A bill would modify the 'net energy billing' solar program

A program designed to promote solar power has been drawing fire from critics who say it's too expensive. Lawmakers are now considering a bill to modify the net energy billing program. The program has enabled the development of dozens of solar projects in Maine, and many more are in the queue. But critics like Maine Public Advocate Bill Harwood say the program could eventually cost Maine ratepayers a minimum of $220 million annually over the next 20 years. Solar advocates say the costs are far less.
