RECOMMENDATIONS: That the Board of Public Utilities: 1. Award Bid No. RPU-2108535 for Conduit and Cable Replacement from Vault V2824 to Vault V542 to the lowest responsive and responsible bidder, Hot Line Construction, Inc., of Brentwood, California, in the amount of $112,124; and 2. Approve Work Order No. 2108535 for a total capital expenditure of $176,000. BACKGROUND: On August 18, 2020, Circuit 1504 out of the Freeman Substation experienced an outage that lasted six hours, affecting 713 residential and commercial customers, including Best Buy, Bank and Magnolia Police Department, among others, all in the vicinity of Magnolia Avenue, Tyler Street and Hole Avenue. Electric Field Crews restored power to the affected customers and found the source of the outage to be a section of burnt underground 12kV feeder cable between vaults V2824 and V542 and were not able to reuse the conduit to pull new cable because the conduit was also damaged. In addition, gas switch GS3-191 inside the vault (V542) contains a critical circuit-tie between Freeman Circuit 1504 and Harvey Lynn Circuit 1282, which is currently inoperable due to the damaged cable. Circuit-ties between electric circuits are critical to the overall reliability and operability of the electric system to continue providing safe and reliable electric service to the area in the event that a portion of one circuit is out of service.
