Alliant Energy Corp. officials have said the Riverside Energy Center, a 603-MW combined-cycle plant near Beloit, Wisconsin, has been out of service since September and needs $25 million in repairs to restart.
The 13-year-old plant was closed in September for regular maintenance, but when Alliant tried to reactivate the plant, “the generating station would not restart properly,” the Wisconsin State Journal reported.
The utility discovered damage in the steam turbine and has filed an insurance claim to cover the cost of repairs. Alliant did not reveal the outage until it appeared on the agenda for the Wisconsin Public Service Commission was published in April.
Alliant plans to return Riverside to service in July.
The company is currently installing a 700-MW gas plant to be called West Riverside adjacent to the existing Riverside plant, along with a 2-MW solar array. Those developments should be finished by 2020.
