Other Events - --------------------- Nevada Legislative Activity On April 18, 2001, Sierra Pacific Resources (the parent corporation of Nevada Power Company (NVP) and Sierra Pacific Power Company (SPPC)) issued a press release announcing that Assembly Bill 369 (AB 369) was passed by the Nevada Legislature, signed by Governor Guinn, and is effective immediately. AB 369 ends utility deregulation in Nevada and prohibits NVP and SPPC from selling their electric generation plants until July 1, 2003. After that date, sales of generation plants would still require the prior approval of the Public Utilities Commission of Nevada (PUCN). The legislation also (1) establishes deferred energy accounting for the utilities which allows them to recover costs for wholesale power over time, (2) establishes as NVP and SPPC's base rates the rates in effect as of March 1, 2001 (including the Comprehensive Energy Plan (CEP) rider and previously filed fuel and purchased power riders through April 1, 2001), (3) provides that the PUCN will take no further action on the NVP and SPPC CEP, and (4) terminates the filing of fuel and purchased power riders by the two utilities pursuant to their earlier settlement with the PUCN. A copy of the press release, dated April 18, 2001, is attached as Exhibit 99.1 hereto. Information regarding the history and contents of AB 369 may be found at www.leg.state.nv.us. ------------------- Item 7.
