Orcas Power and Light reports an outage at 11:30 a.m. Monday cut off service to much of the San Juan Islands.

The utility says it expects to restore service by about 2:30 p.m.

Assistant General Manager Foster Hildreth in Eastsound says the outage was caused by a problem at a Bonneville Power Administration substation.

The outage affects about about 9,000 customers on San Juan, Orcas and Shaw islands. Lopez was not affected.
