The Board of Public <br />Utilities approved a 69kV Breaker and Bus Relay Replacement Project (Work Order 1603079) for <br />$1,700,000 on February 19, 2016. The purchase of this electronic relay equipment is an integral part of <br />this Work Order. The current expenditures for the project are $791,201. <br />The scope of work includes replacing aging electromechanical bus protection relays with <br />microprocessor -based relays at two substations. Relay replacement is a vital element of the Utility 2.0 <br />plan and an enabling technology step for additional automation capabilities. This procurement includes <br />the purchase of bus protection relay panels for Springs and Orangecrest Substations. At this time, the <br />engineering is 60% complete. The remaining work includes final engineering, construction, and testing. <br />0 <br />0 nip <br />I <br />Y� MCI s <br />®� 11 sk 4 <br />to <br />Or <br />-ar 41 <br />Typical Substation Protection Panels <br />
