Avista Shifts Timing for Acquisition of Renewable Resources / Company remains among greenest utilities with 60 percent renewable generation

SPOKANE, Wash., Feb. 17 /PRNewswire-FirstCall/ -- Avista has decided to postpone acquisition of additional renewable resources that were sought in a recent request for proposals, including development of the Reardan Wind Project, until the 2014-2015 timeframe.

Avista is subject to Washington state renewable energy portfolio standards (RPS) and must obtain a portion of its electricity from qualifying renewable resources or through purchase of renewable energy credits. Avista's recently completed 2009 Integrated Resource Plan (IRP) identified that additional qualifying renewable energy is needed by 2016 and that new capacity and energy resources are needed by 2018.

A recent request for proposals (RFP) process investigated the potential to acquire renewable resources identified in the 2009 IRP a few years early in order to take advantage of certain temporary tax credits through the American Recovery and Reinvestment Act of 2009 and through a temporary Washington state sales tax offset program. However, after detailed analysis, the company has decided to delay such renewable resource acquisitions, including construction of its Reardan wind project site, at this time.

"After weighing the near-term cost impacts to our customers against the uncertain long-term benefits of early renewable resource acquisition, the company has decided to postpone acquisition of the renewable resources sought in this bid process," said Dennis Vermillion, Avista Utilities president. "We will be prepared to meet the 2016 RPS requirement in the best way possible for our customers."

In addition to Avista's ongoing commitment to energy efficiency programs, the company has added qualifying renewable generation capacity through technology upgrades at its hydroelectric projects to meet RPS requirements that increase in the year 2016. Avista will continue to evaluate the most cost effective options for future renewable resource acquisitions.

Avista is among the greenest utilities in the U.S. with approximately 60 percent of its electricity produced from clean hydropower and other renewable resources. Avista's carbon footprint is in the smallest ten percent of the top 100 generating utilities.
