Seabrook Nuclear Station in New Hampshire.

Seabrook Station

Providing safe, affordable and reliable energy in New England.

Powering New England Every Day


Seabrook Station is located on 900 acres on the seacoast of southern New Hampshire. The plant is operated in a highly responsible manner and is dedicated to protecting the environment while meeting the energy needs of New England.

Emissions-free power at scale

Seabrook contributes a substantial amount of emissions-free energy to New England. Each year, Seabrook’s operations avoid emissions equivalent to taking approximately 800,000 cars off the road.

Lower energy costs for consumers

Seabrook’s operation lowers consumer energy costs throughout New England by providing a year-round, low-cost, baseload energy supply. Connecticut state officials have attributed cost savings to electric consumers to “millions of dollars…saved by buying power from Millstone and the Seabrook…at rates that are now below the market average in New England.” Seabrook also has a long-term agreement with Vermont utility Green Mountain Power to supply power at a low cost.

Significant regional savings, year after year

Recent ISO New England economic studies show that nuclear generation will continue to reduce emissions for years to come, while saving approximately $500 million annually for New England customers.

Always-on reliability

Seabrook operates at full capacity nearly every day of the year, providing enough energy for approximately 1.4 million homes and businesses. Wind and solar resources’ available generation capacity varies significantly throughout the year.

Reduced reliance on natural gas

Seabrook’s operation significantly reduces New England’s demand for natural gas, which helps keep energy costs low for consumers.

Improved winter reliability

The ISO New England has raised concerns about grid reliability in the winter due to natural gas constraints. Preserving Seabrook’s generation would reduce the risk of rolling winter blackouts.

Supports state climate goals without raising costs

Seabrook’s operation will help states meet greenhouse gas reduction goals, while saving money for customers.
