About this Employer

The Northern California Power Agency (NCPA), a California Joint Action Agency, was established in 1968 by a consortium of locally owned electric utilities to make joint investments in energy resources that would ensure an affordable, reliable, and clean supply of electricity for customers in its member communities. NCPA members include municipalities, a rural electric cooperative, and other publicly owned entities for which the not-for-profit agency provides such services as the purchase, aggregation, scheduling, and management of electrical energy. Most critically for its 16 members, NCPA over the past four decades has constructed and today operates and maintains a fleet of power plants that is among the cleanest in the nation, and that provides reliable and affordable electricity to more than 700,000 Californians. NCPA made a major investment in renewable energy in the early 1980s when it developed two geothermal power plants and financed and built a 250 megawatt hydroelectric facility. Thirty years later, these resources continue to generate reliable, emission-free electricity for its member communities. NCPA’s 796-megawatt portfolio of power plants is approximately 55% greenhouse gas emission-free. NCPA’s mix of geothermal, hydroelectric, and natural gas resources is well positioned to help its members achieve California’s goal of a 60% Renewables Portfolio Standard (RPS) by 2030. NCPA member utilities also have invested heavily in the most environmentally friendly form of electricity—the megawatts that you don’t use. NCPA’s commitment to the environment reflects its status as a not-for-profit public entity whose policies and values are set not by investors, but by locally elected or appointed officials who serve as the energy regulators in the cities, towns, and districts that are members of the Agency.
