Item 8.01 Other Events

Sierra Pacific Resources and Sierra Pacific Power Company

           On November 28, 2007, Sierra Pacific Power Company (SPPC), a wholly-owned subsidiary of Sierra Pacific Resources (SRP), received an order from the Public Utility Commission of Nevada (PUCN) approving recovery of $2.8 million of the requested $22.6 million for settlement payments and legal and consulting fees incurred to resolve claims related to purchase power contracts that were executed during the Western Energy Crisis and terminated by Enron Power Marketing, Inc. in 2002.  As a result of this order and the recognition of legal reserves and other adjustments in prior periods, SPPC will record a net after-tax expense of $7.4 million in the fourth quarter of 2007.  The recovery period was not established in this proceeding but will be determined by the PUCN in a later docket.  The PUCN also granted a carrying charge on the amount approved for recovery.
