Proposals for renewable energy resources sought by Sierra Pacific

Sierra Pacific Resources' (NYSE:SRP) two Nevada-based utility subsidiaries, Nevada Power Co. and Sierra Pacific Power Co., are seeking to add to their renewable energy resources.

Proposals will be considered for the following types of renewable energy resources: solar, wind, geothermal, biomass and other resources eligible for portfolio energy credits under the Nevada renewable portfolio standard. Responses to the company's request for proposals are due back by Nov. 13.

"Renewable resources are an integral part of our energy supply strategy," said Tom Fair, renewable energy executive, Sierra Pacific Resources. "We are currently involved in more than 30 renewable energy projects in Nevada and we want to increase that number significantly."

Legislation requires an increasing percentage of the electricity provided by Nevada Power Co. and Sierra Pacific Power Co. to come from renewable sources. The current standard calls for 20 percent of all the companies' energy to come from renewable resources or energy efficiency measures by 2015.

Parties interested in submitting a response, or those seeking information related to the RFP or renewable energy laws, should go to Sierra Pacific Resources' Web sites at:
