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.[1] It had been owned by the power company Dominion Energy New England since 2005,[2] after it was purchased from PG&E. The plant was owned from August 2013 to April 2015 by Energy Capital Partners,[3] and is now owned by Dynegy. The plant ceased power generation and went offline on June 1, 2017.[4]

Operations[edit source | edit]

The power station began operations in the 1960s and was one of the largest in New England, standing on a 306-acre site.[5] 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:

  • Unit 1: 243 megawatts[5]
  • Unit 2: 240 megawatts
  • Unit 3: 612 megawatts
  • Unit 4: 435 megawatts

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.[5]

Environmental improvements[edit source | edit]

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.

The other area was to reduce the impact on the water consumption and the release of heated water which was killing fish. Dominion began construction of two 500-foot cooling towers in 2009, which were completed in 2011 at a cost of $600 million. This was to create a closed-cycle water cooling system whereby the heated water is cooled by the towers and the water is recycled back to be used in the system again. This stopped the heated water being released back to Mount Hope Bay.[6]

Sale and shutdown[edit source | edit]

In March 2013, the Virginia-based owners Dominion announced that Equipower would purchase the power station.[5] The purchase was closed in August 2013 as part of the $650 million deal that Energy Capital Partners took over three power plants, including two other plants in Illinois, the natural gas-fired Elwood Power Station and the coal-fired Kincaid Power Station.[7] In September 2013, the new owners announced that the plant would be shut down in May 2017, citing low electricity prices as well as high costs to meet environmental standards and maintain aging facilities.[8][7] It was the last coal-fired power station in Massachusetts.[1][9][10]

Environmental groups contest the expansion because of water resources Brayton Point is using from Mount Hope Bay and the heat being discharged from the existing three units. A resident says the plant's continued abuse of the air, land, and water, combined with size, presents a daily threat to the quality of life in the area.

  • 2006
Brayton Point installed pulse jet fabric filters (PJFFs) on Units 1 and 2 in series with the existing Koppers and Research-Cottrell electrostatic precipitators (ESPs)to reduce fine particulate, especially PM 2.5 (particulate with particle diameters of 2.5 microns or less). It also installed a "common" spray dryer absorber (SDA)to reduce sulfur dioxide (SO2) emissions. The SDA was common to, and treated the flue gas from, both Units 1 and 2. A limestone preparation plant and a powdered lime and water slurry injection system, spraying downwards at the top of the SDA, was installed to react with the sulfur dioxide to form calcium sulfate. A powder activated carbon (PAC) storage and injection system was also installed on both Units 1 and 2 to reduce mercury emissions. The PAC was injected upstream of the ESPs. The fly ash was pneumatically conveyed to storage silos. Two "booster" centrifugal fans were installed on each Unit to provide additional induced draft to overcome the pressure drop across the PJFFs. The equipment was supplied by Wheelabrator Air Pollution Control, Inc. (changed to Siemens during the construction) and the general construction contractor was Nicholson & Hall Corp. based in Buffalo, NY. Construction was performed in 2006 and 2007.

The Future of Brayton Point[edit source | edit]

There are extensive plans to balance the negative economic effect that the closure of Brayton Point Station may produce.

Clean Energy Options[edit source | edit]

Clean energy investments tend to stay within the local community. New installations often involve local contractors, who re-spend wages within the region. A switch to clean energy resources can have the effect of recapturing the dollars that, under fossil fuel-based operations, left the state in the form of payments for fuel and equipment. As the Somerset community works with the state and the Brayton Point property owners to determine the best option for reusing the site, they will be carefully considering the future they wish to see for this 234-acre waterfront property. Alternative options such as the Clean Energy Hub scenario show a vision of the future that would allow for the restoration of some of the town’s tax revenues, provide clean, reliable electricity for the region, provide jobs and help advance technological innovation, and reduce pollution and other industrial burdens on the town’s waterfront and surrounding communities.
  • Solar
Solar Farm - panoramio
Utility-scale solar is a renewable energy option for the Brayton Point site. The Clean Energy Center estimated that up to 9 MW capacity of solar panels could be installed at the Brayton Point site under the “Mixed Energy Hub” scenario. To illustrate the differences in scale: a single 9 MW utility-scale project has the same capacity as 1,800 residential rooftop installations at 5 kW each. Solar PV is not expensive to operate and has no fuel costs. And, helpfully, solar power often operates at times when the electric grid needs it most—on hot, sunny days when air conditioning usage increases and energy requirements from the grid are at or near their peak.[11]
  • Off-shore Wind Farm Staging Hub
Wind Farm
The Brayton Point site could become a critical component of offshore wind development in the United States. A 2014 study commissioned by the Clean Energy Center identified Brayton Point as one of the best interconnection points for offshore wind energy in the region.[12] The site was originally developed with two purposes: to support the power produced by the Brayton Point facility and also to act as a regional power hub. The existing high voltage transmission infrastructure at Brayton Point provides a strong backbone for interconnection to surrounding lower voltage systems and could accommodate up to 2,000 MW of offshore wind at an estimated cost of $20 million with minimal investment in new landbased transmission facilities. Depending on the size of interconnection required, necessary new facilities would consist of one or two new buildings, occupying at most 5-10 acres of land on the Brayton Point site. This would leave ample room for additional job- or tax-creating activities.

Energy Legislation to assist with 'renewable resources' at Brayton Point[edit source | edit]

  • 1997 Restructuring Act - Opened the electricity market to competition and innovation, setting the stage to over 109,000 clean energy jobs in the state today.Template:Cite act
  • 2008 Green Communities Act - Created the Green Communities Program, aimed at providing financial assistance for efficiency and conservation projects at the municipal level. To qualify, a municipality must agree to a streamlined permitting process for new renewable projects and meet other benchmarks.Template:Cite act
  • 2016 Energy Diversity Act - Signed into law on August 8, 2016. Sets procurements for 1600 megawatts of offshore wind. These represent the largest purchase of clean energy in the Commonwealth's history.Template:Cite act
  • Implementation of the 2016 Energy Diversity Act - On August 2, 2018, the electric utility companies signed contracts for an 800-megawatt offshore wind farm to be built by Vineyard Wind at a levelized price of 6.5 cents a kilowatt hour for 20 years. The offshore wind farm will result in 3,600 jobs in the region during the construction phase and has a 2021 in-service date.Template:Cite act
