ITEM 5.  OTHER EVENTS

     On August 11, 2003, Sierra Pacific Resources ("SPR"), the parent
corporation of Nevada Power Company and Sierra Pacific Power Company, held a
special meeting of its shareholders at which it received shareholder approval to
issue up to 42,736,920 additional shares of SPR's common stock in lieu of the
cash payment component of the conversion price of SPR's 7.25% Convertible Notes
due 2010 (the "Notes"). SPR issued the Notes on February 14, 2003. The holders
of the Notes are entitled to receive, for each $1,000 principal amount of Notes
surrendered for conversion, (i) 76.7073 shares of SPR's common stock, and (ii)
an amount of cash equal to the market value of 142.4564 shares of SPR's common
stock at the time of conversion (the "cash payment component"), based on the
average closing price of SPR's common stock over five consecutive trading days.
As a result of receiving shareholder approval, SPR has the option of issuing
shares of its common stock in lieu of the cash payment component of the
conversion price of the Notes.
