Item 8.01. Other Events

     On November 8, 2006, the Public Utilities Commission of Nevada (the “PUCN”) approved Nevada Power Company’s (“NPC”) 2006 Integrated Resource Plan (“IRP”) and Sierra Pacific Power Company’s (“SPPC”, and collectively with NPC, the “Utilities”) thirteenth amendment to its 2004 IRP. The Utilities’ IRPs focus on conventional generation, renewable energy, conservation, and transmission projects to meet Nevada’s growing electricity needs while diversifying the fuel mix of the Utilities’ generation portfolios. Included in the PUCN’s approval is Phase 1 of the construction of the Utilities’ Ely Energy Center (“EEC”), a major energy project located near Ely, Nevada consisting of two 750-megawatt coal-fired generation units. In addition, the PUCN approved the development and construction of a 250-mile 500kV transmission line that will deliver electricity from EEC as well as link NPC’s and SPPC’s transmission systems in the southern and northern portions of the state.

     The PUCN approved spending up to $300 million for development activities associated with EEC and established the project as a “critical facility,” thereby allowing it to qualify for incentives that will be determined in a later filing. Specific incentives were also designated for future wind projects based on certain in-service dates. The PUCN also required that NPC file an amendment to its 2006 IRP in early 2008 once elements of the plan, including final costs, can be more accurately estimated. The current estimate for EEC and the 500kV transmission line is approximately $3.7 billion.

     Also approved by the PUCN were the following initiatives:

     For NPC:

• Construction of 600 megawatts of natural gas-fired combustion turbine peaking units at Clark Station to be installed in 2008 and 2009 at an approximate cost of $400 million.

• Installation of approximately $84 million in environmental equipment upgrades for Reid Gardner Units 1-4.

• Expenditure over the next three years of a combined total of approximately $265 million in substation improvements, transmission line upgrades, studies, permitting and land acquisitions.

     For SPPC:

• Refurbishment of some of the company’s diesel-fired generating units and retirement of others.

• Upgrades to the combustion systems to extend the life of Valmy Units 1 and 2.

     A copy of the PUCN’s final order will be available on the PUCN’s website at http://www.puc.state.nv.us/.
