(Update: All power restored )

MADRAS, Ore. (KTVZ) -- More than 1,000 Central Electric Cooperative members lost power for about four hours Thursday due to an equipment issue at the Madras substation.

Co-op officials said line crews began repairs during the noon hour on a blown regulator at the substation.

An outage map around 3:30 p.m. showed more than 500 CEC members out of power north of Redmond and nearly 500 between Madras and Warm Springs. But only about 300 still were reported out of service shortly before 4 p.m.

An update posted to CEC's Facebook page at 3:40 p.m. said power was restored for the last customers just after 3:30 p.m.

Earlier, CEC had stated, "We thank members for their continued patience, as our crews work as quickly and safely as possible."
