Item 5.  Other Events
- ---------------------

On January 29, 2001, Sierra Pacific Resources (the parent corporation of Nevada
Power Company and Sierra Pacific Power Company) issued a press release
announcing the filing of an emergency Comprehensive Energy Plan (CEP).  In the
CEP, filed with the Public Utilities Commission of Nevada, Sierra Pacific
Resources' Nevada Power and Sierra Pacific Power utility subsidiaries are
proposing short-term emergency price increases ranging from zero for certain
low-usage customers to as much as 29 percent for the state's largest energy
users to correct serious imbalances between the cost of wholesale power and
retail prices. The CEP also addresses other issues including long-term
contracts, low income assistance and conservation programs all intended to help
stabilize energy markets in the state.

     A copy of the press release, dated January 29, 2001, and the CEP described
above are attached as Exhibits 99.1 and 99.2, respectively hereto.
