Nevada Power Company Finalizes Purchase of Power Plant From Duke Energy

Oct 13, 2004

Nevada Power Company, a subsidiary of Sierra Pacific Resources (NYSE: SRP), announced that it today finalized its purchase of a partially constructed 1200 MW (megawatts) natural gas-fired combined- cycle power plant from Duke Energy. The company said it expects the facility -- located in the Moapa Valley, 20 miles northeast of Las Vegas -- to be fully operational by the summer of 2006.

The project, along with the financing plan, was approved by the Public Utilities Commission of Nevada in September. The generating facility consists of four natural gas-fired combustion turbines, two steam turbines and four heat recovery steam generators operating in combined-cycle mode.

The financing plan will use a combination of a revolving bank facility, long-term debt and internally generated funds. The acquisition will be completed using a $250 million revolving bank facility with a three-year term that was finalized last week. Total costs to acquire and complete construction of the facility are estimated at $558 million.

Nevada Power Company is a regulated public utility engaged in the distribution, transmission, generation, purchase and sale of electric energy in the southern Nevada communities of Las Vegas, North Las Vegas, Henderson, Searchlight, Laughlin and their adjoining areas. The Company also provides electricity to Nellis Air Force Base, the Department of Energy at Mercury and Jackass Flats at the Nevada Test Site. Nevada Power Company provides electricity to approximately 710,000 residential and business customers in a 4,500 square mile service area.
