Burgess BioPower

A new biomass plant in Berlin is finally producing electricity for Public Service of New Hampshire under a controversial 20-year contract that a report says will cost PSNH ratepayers $125 million more than if the electricity was purchased on the open market...

That estimate came from the consulting firm of La Capra Associates which did the report for the state's Public Utilities Commission as part of a wide-ranging review of PSNH’s operations.

About 51 percent of the wood purchased for the new Burgess BioPower biomass plant in Berlin during its first two months of operation came from New Hampshire, according to a new “sustainability” report filed with the state’s Site Evaluation Committee.

Thirty-five percent came from Maine.

Five percent from Vermont.

Eight percent from Massachusetts.

And "one truck load" came from Canada.
