Brayton Point Power Station was a coal-fired power plant located in Somerset, Massachusetts. It was the largest coal-fired generating station in New England, and was the last coal-fired power station in Massachusetts to provide power to the regional grid. It had been owned by the power company Dominion Energy New England since 2005, after it was purchased from PG&E. The plant was owned from August 2013 to April 2015 by Energy Capital Partners, and is now owned by Dynegy. The plant ceased power generation and went offline on June 1st, 2017.
The power station began operations in the 1960s and was one of the largest in New England, standing on a 306-acre site. The plant had 262 full-time staff, with four power generating units powering in the region of 1.5 million homes using coal, natural gas and oil as its fuel sources. Its energy outputs from the four units were:
Brayton Power Station had been estimated to burn 40,000 tons of coal in three days, and fresh supplies were brought by barge every four days. The coal was brought from Colombia, Kentucky, and Colorado.
With regulations and concerns from the public, Dominion agreed to make investments to improve in the environmental impacts of the plant in two areas.
The first area was to decrease emissions of mercury, sulfur oxide and nitrogen oxide through the implementation of a system called Novel Integrated Desulphurization (NID). The NID injects lime to allow its reaction with the fumes to separate chemicals from the smoke which reduces the emissions of mercury and sulfur oxide. The company also implemented another system to pass the fumes through ammonia to reduce nitrogen oxide emission. The company reported having reduction of those emissions by 90 percents after the installation.
