Utilities Annual GO 165 Reports

G.O. 165 was adopted by the Commission on March 31, 1997, and applies to all electric distribution and transmission facilities (excluding those facilities contained in a substation) that come within the jurisdiction of this Commission, located outside of buildings, including electric distribution and transmission facilities that belong to non-electric utilities.  The requirements of this order are in addition to the requirements imposed upon utilities under General Orders 95 and 128 to maintain a safe and reliable electric system.  GO 165 requires each utility to submit to the commission an annual maintenance report describing its maintenance schedule for the coming year, no later than July 1st .
