RECOMMENDATIONS: That the Board of Public Utilities: Award Bid No. RPU -7746 for the installation of underground facilities on Elizabeth Street to Doty Bros. Equipment Company, of Norwalk, California, in the amount of $118,783.58; and 2. Approve Work Order No. 2014995 for a total capital expenditure of $190,000. BACKGROUND: Riverside Public Utilities' (RPU) ongoing 4kV to 12kV voltage conversion program is an essential component in the replacement of aging infrastructure to meet future load growth, improve electric safety and system reliability. Existing 4kV distribution facilities are becoming obsolete and replacement parts are difficult to procure, as most utilities are converting outdated facilities and standardizing on 12kV facilities for their distribution systems. Upgraded 4kV to 12kV distribution systems are more efficient, easier to maintain, and improve system operations to help reduce outage times during abnormal events. In coordination with James Development, and the City of Riverside Public Works Department, RPU will upgrade existing underground facilities for a future 4 to 12kV voltage conversion project near 3510 Elizabeth Street. James Development is proposing to build two single family residences in the area, and a section of an underground 4kV electric line will be relocated prior to the construction of one of the proposed homes. James Development and the Public Works Department will pay their fair share contribution as part of the 4kV line relocation component, in accordance with Electric Rule 10. James Development will reimburse RPU an amount of $16,514. The Public Works Department will reimburse RPU an amount of $16,488. The total reimbursement amount for this component of the work is $33,028. This project is an important step in facilitating future voltage conversions by creating additional electrical field ties to existing circuits in the surrounding area. Upgrading of distribution facilities for voltage conversions is identified as part of the Utility 2.0 Electric Infrastructure Road Map.
