69kV Subtransmission System Reliability

The new 69kV subtransmission line segments will provide additional connections from Riverside’s existing generation facilities to key substations to relieve the congestion (overloads) and provide sufficient power flow to meet existing electric system demand during normal and planned/unplanned outage conditions within Riverside’s electric system. In addition, the connections of the substations will allow for Riverside’s electric facilities to run effectively and efficiently. The project is designed to increase reliability and strengthen RPU’s subtransmission system.
