TABLE OF CONTENTS

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

     As of July 26, 2005, Nevada Power Company had drawn down an aggregate of $100 million under its $350 million revolving credit facility with Union Bank of California, N.A., as administrative agent, for the purpose of funding its seasonal fuel and power purchase requirements.

Item 8.01 Other Events.

Enron Litigation — Gaming and Partnership Show Cause Proceeding before FERC

     On July 20, 2005, the Federal Energy Regulatory Committee (FERC) issued an order in the Gaming and Partnership Show Cause Proceeding involving Enron Power Marketing, Inc. (Enron), among others, suspending the trial schedule, including the September 7, 2005 trial date, pending FERC review of a recent settlement agreement between the California parties and Enron. The order provides that the trial in this proceeding will convene within seven weeks following FERC’s review of the proposed settlement. FERC also ordered Enron not to take any action to move forward the Bankruptcy Court proceeding, and ordered it to join in any request for postponement of any filing or action in the Bankruptcy Court proceeding. In addition, FERC ordered the remaining parties, including Nevada Power Company (NPC) and Sierra Pacific Power Company (SPPC) to participate in settlement negotiations.

The subject FERC proceeding focuses on Enron’s illicit trading activity in California with various counterparties, including the People of the State of California, California state entities, California utilities and other non-Californian entities (including NPC and SPPC). NPC and SPPC are unable at this time to predict the outcome of the upcoming settlement negotiations, or, if settlement negotiations prove unsuccessful, the outcome of the trial.

Reid Gardner NOAVs

     On July 20, 2005, the Nevada Division of Environmental Protection (NDEP) issued Notices of Alleged Violations (NOAVs) covering a number of issues related to the Nevada Power Company’s Reid Gardner Generating Station in Las Vegas, Nevada. In part, these NOAVs represent reissuances of previously issued NOAVs dated December 2, 2004 which were reported in Sierra Pacific Resources’ Annual Report on Form 10-K for the year ended December 31, 2004. These NOAVs relate to record-keeping, monitoring and other alleged administrative infractions and address additional monitoring and reporting issues for the period September 2002 through December 2004. Also, additional NOAVs were issued concerning intermittent opacity emissions and the monitoring, record-keeping and reporting of such emissions.

All NOAVs are subject to an administrative hearing before the Nevada State Environmental Commission and then to judicial review. NPC is continuing to provide information to NDEP as requested and is engaged in an ongoing dialogue with NDEP, including settlement discussions. Because no penalty has been specified by NDEP and discussions are continuing, management cannot reasonably estimate the amount of any potential monetary penalties that may ultimately be assessed in connection with the alleged violations.

(a)     Financial statements of businesses acquired.

     None.

(b)     Pro forma financial information.

     None.

(c)     Exhibits.
