SOMERSET - Consistently one of the state's largest polluters, Brayton Point Power Station in Somerset is powering down for the last time tonight.

According to the Herald News, the 1,488 megawatt plant will be taken offline at midnight tonight.

Officials for Brayton Point say low electricity prices and the high cost of maintaining aging facilities were contributing factors to Dynegy, Inc.'s decision to close the plant, which at one time supported 170 jobs.

Workers will spend the next two months decommissioning the plant, which is the last coal-fired power station in Massachusetts.
