Sierra Pacific Resources (NYSE: SRP) today announced consolidated net income applicable to common stock of $197.3 million, or 89 cents per share, for the year ended December 31, 2007, compared with net income applicable to common stock of $277.5 million, or $1.33 per share, for 2006. Non-recurring items were the primary factors for the earnings decline. On a recurring basis, the company's adjusted consolidated net income applicable to common stock was $197.7 million, or 89 cents per share, for 2007, compared with an adjusted net income applicable to common stock of $120.3 million, or 58 cents per share, in 2006.

Fourth-quarter consolidated net income applicable to common stock totaled $3.7 million, or 2 cents per share, compared with $26.1 million, or 12 cents per share, in the same 2006 quarter. Non-recurring items were also responsible for the decline in the fourth-quarter comparisons.

The non-recurring factors in 2006 that impacted the 12-month comparisons included a court ruling that allowed Nevada Power Company, the company's southern Nevada utility, to recover approximately $116.2 million, after tax, for fuel and purchased power costs that had previously been disallowed by state regulators and a $40.9 million gain, after taxes, in the 2006 fourth quarter on the sale of Sierra Pacific Resources' partnership interest in the Tuscarora Gas Transmission Company.

The non-recurring factors leading to the lower 2007 fourth-quarter results, when compared with the 2006 fourth quarter, primarily included the $40.9 million after-tax gain from the Tuscarora sale. In addition, there was a deferred energy disallowance of $7.6 million, net of taxes, related to an application to recover legal and settlement costs associated with power supply contracts terminated during the Western Energy Crisis. This disallowance was incurred by Sierra Pacific Power Company, the company's utility in northern Nevada, in November 2007.

Michael Yackira, president and chief executive officer of Sierra Pacific Resources, said, "We are pleased with the company's solid financial and operating results for 2007. Our cash from operating revenues increased significantly. We invested approximately $1.2 billion during the year on capital expenditures that were dedicated to both executing our strategy of building new power plants in Nevada for Nevadans as well as improvements throughout our operations. Also in 2007, Moody's upgraded the utilities to investment grade resulting in three out of four nationally-recognized rating agencies now rating the senior secured debt of the utilities at investment grade. The fourth, Standard & Poor's, revised its outlook to positive during 2007. In addition, the restoration of shareholder common dividends in the 2007 third quarter was a major milestone for our company."

Yackira added, "Despite the nationwide economic downturn, Nevada is once again the nation's fastest-growing state, a position it has held for 20 of the last 21 years. While growth has slowed somewhat, we are still growing and we are focused on ensuring that our customers continue to enjoy reliable utility service at reasonable and predictable rates. We are aggressively pursuing a three-part strategy that calls for increasing energy conservation, expanding our investment in renewable energy, and constructing new traditional power plants that will provide a balanced energy portfolio and will ultimately make our state less susceptible to the volatility of the energy marketplace."

Nevada Power Company 2007 Results

Nevada Power Company reported net income of $165.7 million for 2007, compared with $224.5 million in 2006. The decrease in 2007 was principally the result of the reinstatement of $116.2 million, after taxes, in 2006 for previously disallowed fuel and purchased power costs. Partially offsetting the 2007 decrease was the first quarter reinstatement of interest on deferred energy of $7.2 million, after taxes, associated with the 2006 reinstatement.

For the fourth quarter of 2007, Nevada Power Company reported net income of $4.4 million compared with a net loss of $11.7 million for the same period a year earlier. Fourth quarter results were higher in 2007 primarily due to general rate increases resulting from the 2006 General Rate Case.

The number of residential, commercial and industrial electric customers served by Nevada Power increased by 2.7 percent, 4.6 percent and 4.6 percent, respectively, in 2007 compared with the previous year.

Sierra Pacific Power Company 2007 Results

Sierra Pacific Power reported earnings applicable to common stock of $65.7 million for 2007 compared with $55.4 million in 2006. The increase in 2007 was principally the result of decreased interest expense and increased Allowance for Funds Used During Construction due to the construction at the Tracy Generating Station.

For the fourth quarter of 2007, Sierra Pacific Power reported earnings applicable to common stock of $8.1 million compared with net income of $15.4 million for the same period a year earlier. Fourth quarter results were lower in 2007 primarily because the Public Utilities Commission of Nevada disallowed approximately $7.6 million, net of taxes, related to the utility's application to recover legal and settlement costs associated with power supply contracts terminated during the Western Energy Crisis.

The number of residential, commercial and industrial electric customers served by Sierra Pacific Power increased by 1.6 percent, 3 percent and 5.4 percent, respectively, in 2007 compared with the previous year.

Sierra Pacific Power's retail natural gas revenues decreased in 2007 compared with 2006 primarily due to warmer temperatures in 2007 and decreases in retail rates. The number of residential, commercial and industrial gas customers served by Sierra Pacific Power increased by 2.9 percent, 3.6 percent and 12.6 percent, respectively, in 2007 compared with the previous year.

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.

In addition to net income applicable to common stock for Sierra Pacific Resources, net income for Nevada Power Company and earnings applicable to common stock for Sierra Pacific Power Company, the companies have provided supplementally adjusted net income applicable to common stock for Sierra Pacific Resources, adjusted net income for Nevada Power Company and adjusted earnings applicable to common stock for Sierra Pacific Power Company, all 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, between GAAP net income and adjusted net income for Nevada Power Company and between GAAP earnings applicable to common stock and adjusted earnings applicable to common stock for Sierra Pacific Power Company are provided in the table below. These non-GAAP measures should not be considered as substitutes for the GAAP measures.

Since the years ended December 31, 2007, 2006 and 2005 are affected by items that are primarily non-operational in nature, management believes these non-GAAP financial measures are helpful to assure that they are taken into consideration accurately in assessing the financial performance for the years ended December 31, 2007, 2006 and 2005.

The companies expect to file their Form 10-Ks for the period ended December 31, 2007, with the Securities and Exchange Commission on or about February 25, 2008, at which time the 10-Ks will be available without charge through the EDGAR system at the SEC's website. The Form 10-K reports will also be posted on Sierra Pacific Resources' website, http://www.sierrapacificresources.com/.
