Following investigation of Pacific Gas & Electric's performance during severe storms in early 1995, the Commission concluded it needed to set uniform standards to judge electric utility inspection and maintenance of distribution facilities. The standards would apply to Pacific Gas & Electric, Sierra Pacific Power, Pacific Power and Light, San Diego Gas & Electric, and Southern California Edison. Commission initiative in this matter was endorsed by recently-enacted Assembly Bill 1890 which requires the Commission to adopt such standards no later than March 1997. The proposed standards would require utilities to make certain types of inspections within set annual cycles and, as such, are prescriptive. These prescriptive standards will be a component part of the Commission's larger enforceable reliability measures. The proposed inspection cycles are: O Patrol by foot, vehicle, or aircraft to identify obvious hazards such as leaning poles, vandalized equipment, stray wires, and vegetation that threatens power lines annually in urban areas and at two-year intervals in rural areas. O Detailed inspections of major overhead distribution facilities every five years. O Detailed inspections of major underground facilities every three years. - more - O Detailed inspections for pad-mounted facilities every five years. O Invasive inspection of poles older than 15 years every 10 years. Utilities would be required to submit an annual report to the Commission on their compliance with the inspection standards, and the reports would be available to the public. The Commission also indicated that its next step is to address standards for emergency situations and disasters applicable to all public and private electric utilities. No later than July 1, 1998, each utility is to file with the Commission a performance-based ratemaking approach based on a balanced reward/penalty rate mechanism of no more than $10 million, for maintenance, repair and replacement of major facilities. Parties have 25 days to comment on the proposed standards. After considering the comments, the Commission will adopt final standards. Standards in Effect or Being Considered Earlier this year, the Commission established: O reporting and recording requirements for electric system reliability and individual circuits that persistently perform poorly. O procedures for utility reporting of accidents and incidents which affect public safety or system reliability. O requirements for utility submission of their emergency response plans to the Commission. In addition, the Commission has proposed standards for tree trimming and vegetation management around utility distribution and transmission facilities in urban and suburban areas. ###
