         RENO, NEVADA (August 3, 2001) -- Sierra Pacific Resources (NYSE: SRP)
reported second quarter earnings from continuing operations of 35 cents per
share, partly offsetting its losses in previous quarters from soaring wholesale
power and fuel costs. The company also reported a 33-cent per share one-time
gain from the sale of its water business in the Reno area.

         The restoration of earnings following four consecutive quarters of
losses was due partly to a new law in Nevada that allows the company's two
utility operations, Sierra Pacific Power and Nevada Power, to defer part of
their wholesale power and fuel expenses to protect consumers from the immediate
impact of high wholesale prices, and assures recovery of those costs from
customers at a later date. Wholesale power and fuel costs continued to outpace
the actual revenues collected from customers during the period.

         Including its one-time gain from the water sale and earnings from
discontinued operations, Sierra Pacific's consolidated second quarter earnings
were $54 million, or 69 cents per share of common stock, compared to a net loss
of $20 million, or 26 cents per share during the same quarter in 2000.
Year-to-date 2001 earnings show a net loss of $29 million, or 38 cents per
share, reflecting extraordinary energy costs in the wholesale power markets.

         Contributing to the improvement in second quarter earnings was the
one-time gain of $26 million after taxes, or 33 cents per share, from the sale
of Sierra Pacific Power's water business. A large portion of the gain from the
sale was shared with customers of the water business. The company reported an
additional one-cent per share gain from discontinued water operations.

         Earlier this year, the Nevada State Legislature and Nevada's Governor
approved legislation that ensures the utility subsidiaries have the ability to
recover actual fuel and purchased power costs incurred on behalf of customers.
The deferred balances for wholesale electric power and fuel at Sierra Pacific
Power and Nevada Power as of June 30, are $75 million and $273 million,
respectively.

         "Our state's commitment to recovery of these wholesale costs finally
removes the cloud that has hung over Nevada for some time and restores much
needed financial balance to our company and our state," said Walt Higgins,
chairman and CEO of Sierra Pacific. "This quarter begins to reflect the earnings
performance required to serve Nevada's dynamic, fast-growing economy. This
partial recovery during the quarter is an important step forward in our ability
to invest in Nevada and to attract new energy development in the state and keep
pace with the needs of our customers."
