Frenchtown Township – The Fermi 2 nuclear power plant is back online after being shut down for a series of repairs.

DTE Energy spokesman Stephen Tait said that Fermi 2 in Monroe County was restarted on Sunday.

The plant was offline initially beginning in mid-April following the malfunction of a transformer. The utility had completed its investigation into the transformer malfunction but it stayed offline after an inspection found an issue with a valve on the reactor recirculation system.

The transformer problem appears to have been caused by water in a breaker associated with the transformer.

Fermi 2 supplies 20 percent of the electricity generated by DTE. The Detroit-based utility’s plant is located along Lake Erie in Monroe County’s Frenchtown Township, near Michigan’s border with Ohio.
