Two Rivers Correctional Institution was placed on partial lockdown Saturday during a lengthy power outage that affected approximately 590 Umatilla Electric Cooperative customers northeast of Hermiston.
UEC spokesman Steve Meyers said the outage was due to a transformer failure at the utility’s Power City substation, knocking out power north of Diagonal Road and east of Highway 395. Officials are not sure what caused the transformer to fail, Meyers said.
Kaycie Thompson, public information officer for TRCI, said the prison went into a “modified lockdown,” as opposed to a full lockdown, beginning at 11:43 a.m., though laundry facilities continued to run through the afternoon.
“We do have backup generators, so we’re not in the dark at the institution when the power goes out,” she said.
TRCI contracts to provide laundry services for a number of medical facilities around the area, Thompson explained. About 68 inmates were working on the laundry crew Saturday.
“We were able to manage everything pretty well,” she said.
Power was restored to the prison at 4:42 p.m., according to UEC, and to all customers by 5:46 p.m.
