Building codes, federal standards, and implementation programs by utilities (whose main wholesale supplier is the federal Bonneville Power Administration, BPA) and by nonprofits (such as the Northwest Energy Efficiency Alliance, NEEA) have delivered 20% electricity savings in the Northwest over the past 30 years. The load without those savings represents what consumption levels would have been if efficiency programs and standards were not implemented over the 1979– 2009 period. The Northwest region comprises Washington, Oregon, Idaho, and part of Montana, and a Council of those Governors’ appointees coordinates regional electricity planning under a federal law.
