Electricity was restored to Camp Courtney on Tuesday evening following an outage that left at least 30 families without power for nearly three days, according to Marine officials on Okinawa.

Power returned at approximately 5:35 p.m. when workers switched on the main breaker and began verifying electrical service across the base, Marine Corps Installations Pacific spokesman Maj. Brett Dornhege-Lazaroff said by phone Wednesday.

“I don’t know exactly when each service came back online yet,” he said.

Dornhege-Lazaroff said he did not know what caused the outage.

The base’s Child Development Center remained closed Wednesday. Families were directed to use services at the center on Camp Foster.

The families most affected by the blackout lived on the upper side of the installation. They were authorized to stay in on- or off-base lodging through Wednesday morning, Dornhege-Lazaroff said.

The Facilities Directorate was conducting “final connections and tests for power restoration” as electricity returned, according to a post Tuesday evening on the Camps Courtney and McTureous Facebook page.

To assist those affected, the base food pantry offered perishable goods Wednesday afternoon at the commissary and chapel to families and troops living in the barracks who lost food during the outage.

“Our focus whenever these things happen is to try and get power back as quickly as we can and mitigate the effect on the tenants and people living on the base,” Dornhege-Lazaroff said. “Afterwards we’ll look at the claims process and look at what happened.”
