NV Energy, Inc., Reports First Quarter Results

Las Vegas – NV Energy, Inc. (NYSE: NVE) today announced a consolidated net loss of $22.2 million, or 9 cents per share, for the quarter ended March 31, 2009, compared with consolidated net income of $24.1 million, or 10 cents per share, for the same period in 2008.

The decrease in earnings in the first quarter 2009 compared to the same period in 2008 was the result of higher other operating and maintenance expenses, depreciation, and financing expenses primarily attributable to power plant investments, and lower revenues due to milder weather. Other income was less in 2009 due to recognition of certain non-recurring items in 2008.

“Much of the first quarter-to-quarter decline is attributable to expenses associated with new generating facilities in southern Nevada that have yet to generate a return to shareholders which we expect will be addressed in our current general rate case,” said Michael Yackira, president and CEO of NV Energy. “In addition, growth in both our northern and southern Nevada service territories continued to slow, demonstrating that our company is not immune to the economic challenges that have gripped our state and nation.”

NV Energy’s two utilities contributed gross margin of $283.9 million in the first quarter 2009, $7.7 million higher than the first quarter 2008. Although NVE’s consolidated revenues were lower in the first quarter, the increase in consolidated gross margin was primarily due to the effect of the northern utility’s 2007 General Rate Case effective July 1, 2008.

The average number of residential, commercial and industrial electric customers in southern Nevada increased by 0.6 percent, 0.4 percent and 3.3 percent, respectively, in the first quarter 2009, compared with the average customer counts for the same period in 2008. In northern Nevada, the average number of residential customers remained unchanged while commercial and industrial electric customers increased by 1.7 percent and 4.6 percent, respectively, in the first quarter 2009, compared with the first quarter 2008.

Webcast Scheduled for 7 a.m. PDT Wednesday, April 29

Senior management of NV Energy will review the company’s 2009 first quarter financial results, regulatory issues and other matters during a conference call and live webcast Wednesday, April 29, at 7 a.m. Pacific Daylight Time.

Gross margin is presented by Nevada Power Company d/b/a NV Energy and Sierra Pacific Power Company d/b/a NV Energy 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.
