The plant site, located on the shore of the Middle Branch of the Patapsco River, was used for the generation of electric power for over one hundred years before being shut down on June 1, 2019.
[4] Electric output from the Gould Street Generating Station was provided by Unit 3, which consists of a natural gas-fired boiler and steam turbine.
[5] The turbines and generators at the plant, not being necessary to serve the electric load at that time, were then sold and shipped to a silver mining company in Mexico.
[5] The 100 MW generator of Unit 3, installed in 1952, was originally powered by a turbine with steam provided from a coal-fired boiler, but was later converted from coal to burn No.
[1] Constellation Energy repaired the turbine, modified Unit 3 to burn natural gas only,[1] and reactivated the plant in June 2008.
