SIERRA PACIFIC RESOURCES REPORTS QUARTERLY FINANCIAL RESULTS

     Las Vegas, Nev. - Sierra Pacific Resources (NYSE: SRP) today reported a
consolidated second quarter loss of $41.9 million, or $(0.41) per share,
compared with net income of $54.0 million, or $0.69 per share, in the same
prior-year quarter.

     The largest factor impacting the 2002 second quarter results was a one-time
charge related to the disallowance of $53.1 million in power costs paid from
December 2000 through November 2001 by Sierra Pacific Power, the company's
electric utility in northern Nevada. Other contributing factors to the decline
included cooler weather in May and energy conservation by customers that
resulted in lower demand.

     For the second quarter, the Sierra Pacific Power subsidiary had a loss of
$34.9 million, compared with net income of $29.5 million in the second quarter
of 2001. Nevada Power Company, the company's utility in southern Nevada, earned
$5.7 million, compared with $33.1 million in the same period a year ago, on a
stand-alone basis (excluding the equity in the earnings losses of the parent
company).

     Walt Higgins, Sierra Pacific Resources' chairman, president and chief
executive officer, said: "We are pleased that Nevada Power Company returned to
profitability



                                                                               2

during the second quarter, particularly as a precursor to the third quarter
which is traditionally a period of peak demand for our company. Except for the
one-time charges related to the Sierra Pacific Power deferred energy case
disallowance, both Sierra Pacific Power and our company overall would have been
profitable.

     For the first half of the year, Sierra Pacific Resources had a net loss of
$347.4 million, compared with a loss of $29.4 million for the comparable period
in 2001. The primary cause for the 2002 loss was the March 29 disallowance of
$434.1 million in deferred energy costs for Nevada Power Company.

     During the recently concluded quarter, residential electric revenues
decreased at Nevada Power by 3.3 percent compared to the same quarter in 2001
because of cooler weather. Second quarter commercial and industrial revenues
increased by 8.1 percent and 14.2 percent, respectively, due in part to
increases in rates and customer growth.

     Electric revenues for Sierra Pacific Power residential, commercial and
industrial customers for the second quarter fell by 4.1 percent, 2.5 percent and
8.2 percent, respectively, compared with the same quarter in 2001. This resulted
from cooler weather in May and a rate decrease for residential customers
effective on June 1, 2002.
