TABLE OF CONTENTS

Item 8.01. Other Events

     On July 1, 2005, Sierra Pacific Power Company, a subsidiary of Sierra Pacific Resources, filed a Base Tariff Energy Rate (BTER) request with the Public Utilities Commission of Nevada (PUCN) seeking to update its rates in the face of escalating energy prices to reflect increasing costs for fuel and power purchased to serve its customers. The filings include an update of electric rates for northern Nevada customers, and a rate update for natural gas customers in the Reno-Sparks metropolitan area.

     If approved, the company’s filing related to its electricity customers in northern Nevada calls for a $32.3 million annual increase in rates which, for the typical residential customer using 715 kilowatt hours of electricity, would mean a 3.2 percent increase, or a rise of approximately $2.80 per month. For natural gas customers, the $29 million annual increase means that the typical natural gas customer using 59 therms of natural gas would see an 18.9 percent increase, or approximately $12 per month.

     Following review by the PUCN, new electric rates would become effective October 1, 2005, with new natural gas rates effective November 1, 2005.
