The outage in Hidden Valley Lake and Middletown was first reported just after 11:30 a.m., according to Pacific Gas & Electric spokesman J.D. Guidi.
The cause was a broken cross arm on a power pole, Guidi said.
Approximately 252 customers were impacted, according to Guidi.
He said 55 customers had their power restored just after 3 p.m., and by 3:30 p.m. the power went back on for another 60 homes.
The lights came on for the remaining 137 customers at 3:48 p.m., Guidi said.
