Prairie Island 1 power back up after unplanned outage

The Xcel Energy (NYSE:XEL) Prairie Island 1 nuclear unit in Minnesota is returning to service following a reactor trip on May 31.

The nuclear unit was listed at 30% generation early June 4, according to data from the Nuclear Regulatory Commission (NRC). The unit is “on its way to full power, but not yet,” a company spokesperson said when contacted by GenerationHub.

The unit had been shut down by plant operators in response to a malfunction in the feedwater system. The feedwater system supplies water to the steam generators.

The Prairie Island nuclear plant is 28 miles southeast of Minneapolis-St. Paul and about six miles northwest of Red Wing. When the plant’s two pressurized water reactors are running at full power, they generate 1,076 MW.
