Millstone Nuclear Power Plant, Connecticut | USA Power Generation

Millstone is a nuclear power plant located in Connecticut, United States, operated by Dominion Energy Nuclear Conn Inc. As a nuclear facility, it provides reliable, low-carbon baseload power to the New England grid. With a capacity of 2162.9 MW, it ranks among the larger nuclear plants in the country. The plant operates under the regulatory oversight of the U.S. Nuclear Regulatory Commission (NRC), which enforces stringent safety and operational standards. Nuclear power generation in the U.S. is also subject to environmental regulations under the Clean Air Act, though nuclear plants emit negligible greenhouse gases during operation. The facility uses pressurized water reactor technology, typical for its generation. Millstone plays a critical role in Connecticut's energy mix, contributing to grid stability and reducing reliance on fossil fuels. Its location on the Long Island Sound provides access to cooling water, a key requirement for nuclear operations. The plant supports local employment and the regional economy through its continuous operation.

Nuclear power generation produces no direct CO2, SOx, or NOx emissions during operation, making Millstone a low-carbon energy source. However, the plant's location near the coast and populated areas requires careful management of cooling water discharge and radiological safety. The facility's large capacity means it displaces significant fossil fuel generation, contributing to regional air quality improvements.
