What are Peaker Plants?<\/h2>\n

Peaker power plants are power plants that operate only when electricity demand is especially high and the grid needs additional generation beyond what is routinely available. They are most often used during periods of extreme heat or cold, when electricity use reaches its highest levels.<\/p>\n

Environmental Concerns<\/h3>\n

Massachusetts’ fossil fuel peaker plants are among the state’s oldest, least efficient, and most expensive power plants to operate. Because they are designed to run only during periods of peak electricity demand, they generate relatively small amounts of electricity while producing disproportionately high emissions and operating costs. Most burn natural gas, fuel oil, or both, releasing carbon dioxide (CO\u2082), nitrogen oxides (NO\u2093), fine particulate matter (PM\u2082.\u2085), sulfur dioxide (SO\u2082), and other pollutants that contribute to climate change and degrade local air quality.<\/p>\n

Although peaker plants typically operate for only a small percentage of the year, they are called upon during periods of extreme heat or cold, when electricity demand is highest and air quality may already be compromised. Pittsfield Generating, for example, continues to be the city’s largest individual source of greenhouse gas emissions despite operating less than five percent of the year.<\/p>\n

In Massachusetts, there are 21 oil-and gas-fired peaker plants, which are well over 30 years old, and many are over 50 years old. This aging infrastructure is far less efficient than modern generating technologies. Older plants generally require more fuel to produce the same amount of electricity, resulting in higher emissions and operating costs. As these facilities continue to age, maintenance needs increase and reliability concerns become more significant.<\/p>\n

Many peaker plants are located in or adjacent to Environmental Justice communities, where residents already experience disproportionately high cumulative pollution burdens. Air pollutants emitted by peaker plants\u2014including nitrogen oxides, sulfur dioxide, and fine particulate matter\u2014contribute to the formation of ground-level ozone and smog and are associated with increased risks of asthma attacks, respiratory disease, cardiovascular disease, stroke, adverse birth outcomes, and premature death. Children, older adults, and people with pre-existing heart or lung conditions are especially vulnerable to these health impacts.<\/p>\n<\/div>\n<\/div>\n\n
