Sierra Pacific Resources Reports First Quarter 2008 Earnings

PRNewswire-FirstCall
LAS VEGAS
Apr 23, 2008
5:00am

Sierra Pacific Resources (NYSE: SRP) today announced consolidated net income applicable to common stock of $24.1 million, or 10 cents per share, for the quarter ended March 31, 2008, compared with net income applicable to common stock of $15.6 million, or seven cents per share for the same period in 2007. The improvement in earnings is primarily a result of a mid-year 2007 rate increase, customer growth, and favorable impact of Allowance for Funds Used During Construction related primarily to the Clark Power Station in Las Vegas and the Tracy Combined Cycle Plant near Reno.

Michael Yackira, president and chief executive officer of Sierra Pacific Resources, said, "We are pleased with the company's continuing solid financial and operating results. We believe our positive momentum will be maintained as we continue to aggressively pursue the three-part strategy that calls for increasing energy conservation, expanding development and investments in renewable energy and increasing Nevada's generation capacity utilizing traditional fuels."

"Yesterday's announcement of our agreement to acquire Reliant Energy's 598-megawatt (MW) natural gas-fired, combined-cycle Bighorn Generating Station in southern Nevada is another step forward in our strategy to assure that we have reliable electric service in Nevada," Yackira added. "In northern Nevada, a new 541 MW unit at our Tracy Generating Station will begin operation before this summer. We are nearing completion of two new gas-fired power projects at our Clark Generating Station in Las Vegas that will total approximately 600 MW of peaking capacity and will be opening this spring and summer. These projects will reduce the impact for our customers from the effects of price volatility found on the open market. We also recently announced plans for the company to invest directly in two renewable energy projects in Nevada."

Sierra Pacific Resources' utilities, Nevada Power and Sierra Pacific Power contributed electric gross margin of $165 million and $94 million, respectively, for the quarter ended March 31, 2008 compared with $132 million and $92 million, respectively, in the same period in 2007; and $16.5 million in gross margin from Sierra Pacific's gas business for the quarter ended March 31, 2008 compared with $15 million in the same period in 2007.

Megawatt hour sales were up 2.4% at Nevada Power and flat at Sierra Pacific Power for the first quarter 2008 when compared with the first quarter 2007. Retail sales measured in decatherms were up 7.9% for Sierra Pacific's Gas Distribution Business. The number of residential, commercial and industrial electric customers served by Nevada Power increased by 1.5 percent, 3.7 percent and 3.4 percent, respectively, in the first quarter of 2008 compared with the 2007 first quarter. Sierra Pacific Power's residential, commercial and industrial electric customers increased by 1.2 percent, 2.5 percent and .7 percent, respectively, in the first quarter of 2008 compared with the 2007 first quarter. The number of residential, commercial and industrial gas customers served by Sierra Pacific Power increased by 1.5 percent, 3.1 percent and 35.0 percent, respectively, in the first quarter of 2008 compared with the 2007 first quarter.

The companies expect to file their Quarterly Reports on Form 10-Q for the period ended March 31, 2008, with the Securities and Exchange Commission on or about May 2, 2008, at which time the Form 10-Q reports will be available without charge through the EDGAR system at the SEC's website.

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.
