For Immediate Release

Sierra Pacific Power Company, a wholly owned subsidiary of Sierra Pacific Resources (SRP:NYSE), today made its annual mandatory deferred energy filing with the Public Utilities Commission of Nevada (PUCN) seeking to recover the costs of fuel and power purchased on behalf of its customers, plus a filing to address costs associated with energy conservation programs. When the two filings are combined it means the typical residential customer could see an increase of 1.3%, or an average of $1.33 per month beginning in June.

Sierra Pacific Power's filing is seeking to recover -- on a dollar-for-dollar basis with no profit to the company -- deferred energy expenses incurred from December 1, 2003 through November 30, 2004. It also proposes a new rate going forward that more accurately reflects the current prices of fuel to generate electricity and power purchases from neighboring utilities to serve customers.

Mary Simmons, Sierra Pacific Power's vice president of external affairs, said today's filing is designed to lessen the impact of the increase by proposing to spread the recovery of the deferred balance over two years and implementing the new rate on June 1, 2005, a time when rates approved in previous cases are set to expire. If approved by the PUCN, the typical residential customer using 715 kilowatt hours of electricity would see a monthly bill increase from $82.77 to $84.10.

Simmons pointed out that over the past three years Sierra Pacific has attempted to absorb some of the volatility of the energy markets by increasing the time for recovery of deferred energy balances as well as timing the implementation dates."This helps to keep our rates more stable and costs more manageable for our customers,"Simmons said.

She attributed the increase to the rising costs of natural gas and other energy sources that have increased significantly during the past 18 months.

The PUCN will set hearings in the next few months to conduct a thorough review before making a decision on Sierra Pacific's request.
