Nevada Power Company to Complete Construction of Former Duke Energy Power Plant in Nevada

Oct. 14, 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.
