Established in 1968, the Northern California Power Agency is a California joint action agency. NCPA membership is open to municipalities, rural electric cooperatives, irrigation districts and other publicly owned entities interested in the purchase, aggregation, scheduling and management of electrical energy. For nearly three decades, NCPA has successfully provided scale and skill economies devoted to the purchase, generation, transmission, pooling and conservation of electrical energy and capacity for its members. With the onset of electric utility restructuring, the agency has become a primary supplier of power scheduling and interchange management services to power marketers and public agencies. NCPA operates through a number of business units that include administrative services, generation services, legislative and regulatory services and power management. Northern California Power Agency has a location in Middletown, Calif.
