The Bonneville Power Administration (BPA), headquartered in Portland, Oregon, is a federal agency that markets wholesale electricity and transmission to Pacific Northwest utilities as well as to some large industries. BPA provides about a third of the electricity used in the Northwest delivered over a network of 15,000 miles of transmission lines. The agency aims to be a national leader in providing high reliability, low rates, as well as responsible environmental stewardship and accountability to its stakeholders. Energy efficiency has been BPA’s biggest resource addition over the last 25 years. In fact, over that span of time , BPA has acquired more than 1,000 average megawatts of energy conservation, which is more than enough to serve a city the size of Portland, Oregon, on an ongoing basis. In fiscal year 2007 alone, BPA delivered 58 aMW of energy efficiency into the Northwest -- the equivalent energy to power 50,000 homes for an entire year. BPA founded the Northwest Energy Efficiency Alliance in 1996 and continues to be its largest funder and supporter.
