Item 7.01 Regulation FD Disclosure

NV Energy, Inc. (NVE) announced today that the in-service date for the One Nevada Transmission Line (“ON Line”) under construction in Eastern Nevada will be delayed by at least three months. ON Line was previously expected to be in service by December 31, 2012. The ON Line project is jointly owned by NVE’s operating utilities and Great Basin Transmission South LLC, an affiliate of LS Power. The delay is attributed to addressing recent wind-related damage sustained by some of the tower structures. As a result of the damage and as a precautionary measure, the ON Line owners have directed construction crews to lay down certain existing tower structures and cease erection of further tower structures until the owners have completed an assessment of the situation. Other construction activities that are focused on safety and are unrelated to the wind-damage are continuing while the owners work to resolve and repair the wind-related damage, ascertain the root causes of the damage, and otherwise determine what project modifications will be necessary to ensure project safety and reliability. As a result, NVE is also delaying the merger application of its two utilities, Sierra Pacific Power Company d/b/a NV Energy and Nevada Power Company d/b/a NV Energy.
