Spokane, Washington [RenewableEnergyAccess.com] Avista Utilities, an operating division of Avista Corp., is seeking proposals from suppliers of renewable energy to meet its projected need for additional cost-effective energy resources. The request for proposals (RFP) is based on future growth in demand for electricity as identified in Avista’s 2005 Integrated Resource Plan (IRP).Avista currently supplies about 54 percent of its electric needs through renewable hydropower. Other renewable resources used by Avista include wood waste and wind power. Avista is now seeking proposals to add approximately 35 average MW (aMW) of long-term renewable energy supplies to begin during the fourth quarter of 2007. Avista’s IRP identifies a preferred resource strategy consisting of a mix of five resource categories including conservation, upgrades to existing generation facilities, wind, other renewables and coal. In total, conservation, plant upgrades and renewables provide more than half of new load requirements over the IRP time frame. “We are actively pursuing various elements of our resource strategy. In this RFP we are addressing the first of those components to help secure resources at the lowest reasonable costs for our customers,” said Dick Storro, director of power supply for Avista Utilities. “Later this year we will also be looking for proposals to implement additional effective conservation programs and other elements of our preferred resource strategy.” According to projections, energy deficits on a quarterly basis will begin in 2007 and capacity deficits on a quarterly basis begin in 2009. Annual energy deficits are projected to begin in 2010, with loads exceeding resource capability by 40 aMW. Energy deficits rise to 360 aMW in 2016. Responses to the renewables request for proposals (RFP) are due on February 1, 2006.
