Sierra Pacific Resources (NYSE: SRP) today reported consolidated net income applicable to common stock of $152.2 million, or 69 cents per share, for the third quarter of 2007, compared with $222.2 million, or $1.05 per share, for the same period in 2006. For the nine months ended September 30, 2007, the company reported net income applicable to common stock of $193.6 million, or 87 cents per share, compared with $251.3 million, or $1.23 per share, for the same period a year earlier.

The decreases in net income for the three- and nine-month comparisons were principally the result of a 2006 third quarter Nevada Supreme Court ruling that allowed Nevada Power Company, the company's electric utility in southern Nevada, to reinstate previously disallowed deferred energy costs of approximately $180 million, before tax, or $116.2 million, after tax. Excluding the 2006 reinstatement of deferred energy as mentioned above, the company's operating results for the 2007 periods showed significant improvement over the comparable prior-year periods.

The positive factors affecting net income for the 2007 third quarter, when compared with the prior year quarter, included higher rates at Nevada Power Company, continued customer growth at both Nevada Power Company and Sierra Pacific Power Company, the company's other utility; a settlement with the Public Utilities Commission of Nevada regarding accrued interest on Nevada Power Company's 2001 deferred energy case; increased AFUDC for the construction of the Clark Peaking Units at Nevada Power Company and the Tracy Generating Station at Sierra Pacific Power Company, and decreased interest charges driven by reduced holding company debt as well as various re- financings of debt at both utilities in 2006 and 2007 at lower interest rates.

"We are very pleased with these results and our company's improved operating performance," said Michael Yackira, president and chief executive officer of Sierra Pacific Resources. "We are continuing to benefit from the effects of strong, albeit slower, customer growth throughout Nevada, which has driven our investments in infrastructure. Our goal is to continue to reduce Nevada's dependence on purchased power from sources outside the state and to diversify our fuel mix. In addition, we have had outstanding operational performance."

Yackira added, "We have also experienced improved financial strength and performance. Most recently, Moody's upgraded the senior secured debt of both utilities to investment grade. With this action, three of the four agencies rating our company's credit recognize the improvement and rate both utilities' senior secured debt investment grade."

Retail electric revenues for the three and nine months ended September 30, 2007, increased compared with the same periods in 2006 due to increases in retail rates, customer growth and hotter weather. Sierra Pacific Power's retail natural gas revenues were comparable for the three months ended September 30, 2007 to the same period a year ago. Retail gas revenues decreased for the nine-month period ended September 30, 2007 as compared with the same period in 2006 primarily due to warmer winter weather and decreases in retail rates. Other operating and maintenance expenses for the three and nine months ended September 30, 2007 increased compared with the same periods in 2006, primarily due to higher regulatory amortizations, and operating and maintenance costs at the fleet of power plants at Nevada Power Company.

This press release contains forward-looking statements regarding the future performance of Sierra Pacific Resources and its subsidiaries, Nevada Power Company and Sierra Pacific Power Company, within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are subject to a variety of risks and uncertainties that could cause actual results to differ materially from current expectations. For Sierra Pacific Resources, these risks and uncertainties include, but are not limited to, Sierra Pacific Resources' ability to maintain access to the capital markets, the financial performance of Sierra Pacific Resources' subsidiaries, Nevada Power Company and Sierra Pacific Power Company, and the discretion of Sierra Pacific Resources' Board of Directors with respect to the payment of future dividends based on its periodic review of factors that ordinarily affect dividend policy, such as current and prospective financial condition, earnings and liquidity, prospective business conditions, regulatory factors, and dividend restrictions in Sierra Pacific Resources' and its subsidiaries' financing agreements. For Nevada Power Company and Sierra Pacific Power Company, these risks and uncertainties include, but are not limited to, unfavorable rulings in their pending and future regulatory filings, their ability to maintain access to the capital markets for general corporate purposes and to finance construction projects, and their ability to purchase sufficient fuel, natural gas and power to meet their power demands and natural gas demands for Sierra Pacific Power Company. Additional cautionary statements regarding other risk factors that could have an effect on the future performance of Sierra Pacific Resources, Nevada Power Company and Sierra Pacific Power Company are contained in their Quarterly Reports on Form 10-Q for the quarter ended June 30, 2007 and their Annual Reports on Form 10-K for the year ended December 31, 2006, filed with the SEC. The Companies undertake no obligation to release publicly the result of any revisions to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

Gross margin is presented by Nevada Power Company and Sierra Pacific Power Company in order to provide information by segment that management believes aids the reader in determining how profitable the electric and gas business is at the most fundamental level. Gross margin, which is a "non-GAAP financial measure" as defined in accordance with SEC rules, provides a measure of income available to support the other operating expenses of the business and is utilized by management in its analysis of its business.

Nevada Power Company and Sierra Pacific Power Company believe presenting gross margin allows the reader to assess the impact of regulatory treatment and their overall regulatory environment on a consistent basis. Gross margin, as a percentage of revenue, is primarily impacted by the fluctuations in regulated electric and natural gas supply costs versus the fixed rates collected from customers. While these fluctuating costs impact gross margin as a percentage of revenue, they only impact gross margin amounts if the costs cannot be passed through to customers. Gross margin, which Nevada Power Company and Sierra Pacific Power Company calculate as operating revenues less fuel and purchased power costs, provides a measure of income available to support the other operating expenses. Gross margin changes based on such factors as general base rate adjustments (which are required to be filed by statute every three years) and reflect Nevada Power Company and Sierra Pacific Power Company's strategy to increase internal power generation versus purchased power, which generates no gross margin. Reconciliations between GAAP operating revenues and gross margin are provided in tables herein. These non- GAAP measures should not be considered as substitutes for the GAAP measures.

The companies expect to file their Form 10-Qs for the period ended September 30, 2007, with the Securities and Exchange Commission on or about November 2, 2007, at which time the 10-Qs will be available without charge through the EDGAR system at the SEC's website. The Form 10-Q reports will also be posted on Sierra Pacific Resources' website, http://www.sierrapacificresources.com/.

  Clarification of Adjusted Net Income

In addition to net income applicable to common stock for Sierra Pacific Resources and net income for Nevada Power Company, the companies have provided supplementally adjusted net income applicable to common stock for Sierra Pacific Resources and adjusted net income for Nevada Power Company, both of which are non-GAAP financial measures, in order to provide information that management believes aids the reader in determining net income after taking into consideration the item that is primarily non-operational in nature. Reconciliations between GAAP net income applicable to common stock and adjusted net income applicable to common stock for Sierra Pacific Resources and between GAAP net income and adjusted net income for Nevada Power Company are provided in the table below. These non-GAAP measures should not be considered as substitutes for the GAAP measures.

Since the three and nine month periods ended September 30, 2006 are effected by an item that is primarily non-operational in nature, management believes the non-GAAP financial measures are helpful to assure that they are taken into consideration accurately in assessing the financial performance for the three and nine month periods ended September 30, 2007.
