PUCN Order

Nevada Power Company, Sierra Pacific Power Company and Sierra Pacific Resources

On June 22, 2007, the Public Utilities Commission of Nevada (the “PUCN”) issued a final order authorizing Nevada Power Company and Sierra Pacific Power Company (together, the “Utilities”) to issue secured and unsecured long-term debt securities in an aggregate amount not to exceed $3.91 billion and $1.72 billion, respectively, through the period ending December 31, 2009. A portion of the amounts authorized for each of Nevada Power Company and Sierra Pacific Power Company ($1 billion and $300 million, respectively) is contingent upon the PUCN’s final approval of the Utilities’ Ely Energy Center, which will include two 750 MW coal-fired plants and a 250-mile transmission line to interconnect the Utilities’ systems. The PUCN’s order also eliminates restrictions on the ability of the Utilities to pay dividends to its parent, Sierra Pacific Resources.
