MORRIS – Operators at Exelon Generation’s Dresden Station took Unit 3 offline at 3:35 a.m. Saturday to perform maintenance work on the system that cools the unit’s generator.
The generator transforms the mechanical energy of the spinning turbine into electrical energy, according to a news release from Exelon. It is on the non-nuclear side of the plant.
This work cannot be performed while the unit is in operation, according to the news release. Customers’ electrical service should not have been affected, as Dresden Unit 2 continued to generate electricity while Unit 3 was offline.
Dresden Generating Station is in rural Grundy County. The station’s two operating units can produce more than 1,800 megawatts net of electricity, enough to power 1.2 million average homes, according to the news release. Dresden Unit 1, which began commercial operation in 1960 and was retired in 1978, has been designated a Nuclear Historic Landmark by the American Nuclear Society.
