The last coal-fired power plant in Massachusetts shut down on Wednesday, 57 years after it first opened in Somerset.

The plant stood along Mount Hope Bay and served as an obstacle to environmentalists and fishermen since its inception. Groups like Conservation Law Foundation have said the plant was the number one leader in air pollution in New England. The environmental concerns led to the construction of two cooling towers in the last decade, but shortly following the towers' completion, a decision was made to close the plant, according to U.S. News & World Report.

The decision to close Brayton Point, which straddles the Massachusetts-Rhode Island state line and was reportedly the largest coal plant in New England, came in 2014. New Jersey-owner Energy Capital Partners chose to shut down operations after the firm could not reach an agreement with power-grid operator ISO New England, according to the Providence Journal.

Coal is one of the largest sources of energy around the world, but mining for the resource has been proven to cause negative health effects and environmental impacts, including acid rain, tainted waterways and carbon dioxide release adding to global warming.

The plant's closure comes in the same week President Donald Trump's administration is expected to withdraw the United States from the Paris Climate Agreement, a global agreement to combat climate change. Trump's administration has promised to revive the coal mining industry, which has been in decline due to use of cheaper resources like natural gas.

Somerset received $3 million from the Massachusetts Department of Energy and Resources last year, the Herald News reported. Those funds will reportedly replace the offset of tax losses from the closed plant in the fiscal year 2017.
