The Sagebrush Line at 230kV, and of approximately similar connected capacity as theSCE 66kV network, serves as a dramatic comparison, showing what the utility grid couldbe. Although the Sagebrush Line is considered by the utility to be lower-cost construction,it has performed extremely well and reliably – far more so than the utility grid. TheSagebrush Line has important reliability features that are missing from the 66kV grid,such as an overhead static ground line that provides substantial lightning protection andgoodphysical protection against vehicle and fire damage, which have so impacted the 66kVgrid. The monitoring and control capabilities of the Sagebrush Line are excellent andprovide operators with key operating data that would bemost useful on the 66kVnetwork.
