Founded in 1937, Orcas Power & LIght Cooperative provides reliable service to 20 islands in San Juan County. OPALCO serves 11,075 members through 13,538 accounts. Their main challenge is installing and maintaining submarine cables and an underground distribution system; more than 80% of OPALCO’s distribution system is underground. OPALCO is committed to energy efficiency and has a robust interconnection program. More than 70 members generate their own local renewable energy and are interconnected to their system mostly through net metering and buy-sell arrangements.
