Constellation has announced its intention to explore the possibility of doubling the nuclear capacity at its Calvert Cliffs site in Maryland. This project involves building two new nuclear units with a total capacity of 2,000 megawatts (MW), bringing the site’s total electricity production to 4,000 MW.
This plan is part of a broader strategy to strengthen clean energy sources in the state. In addition to the nuclear project, Constellation is considering the installation of an 800 MW battery storage system and adding 700 MW of gas-fired power, with a future possibility of converting to carbon-free hydrogen. These investments aim to increase the share of clean energy in Maryland’s energy mix, which could rise from 50% to 70% by 2030.
The Calvert Cliffs nuclear plant, the only one in Maryland, currently generates 40% of the state’s electricity and 80% of its clean energy. As part of the project, Constellation also proposes extending the operating life of its two existing pressurized water reactors, which were originally set to shut down in 2034 and 2036, while increasing their capacity by an additional 190 MW.
Forecasts for growing energy demand, particularly due to economic expansion, make it necessary to develop new reliable and sustainable energy production capacities. Joe Dominguez, President and CEO of Constellation, emphasized that these investments would be made without increasing electricity rates for consumers, provided there is a favorable legislative framework from Maryland’s policymakers.
Constellation is committed to working with local authorities and stakeholders to advance these projects while ensuring that the investments do not incur additional costs for families and businesses in the state.
