MORRIS, Ill. - Dresden Unit 2 automatically shut down this morning after experiencing an electrical transient on a power transformer on the non-nuclear side of the plant. The plant responded as expected, safely and without incident. Operators are looking into the cause of the transient.
The Dresden Unit 2 shutdown will not have an impact on electrical service to Exelon customers. Dresden Unit 3 continues to operate at full power.
Dresden Generating Station is approximately 60 miles southwest of Chicago. The station's two nuclear energy units can produce a total of more than 1,800 megawatts at full power - enough carbon free electricity to power more than 1.2 million typical homes. 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.
