230 kV Reliable Transmission System


In 2017, GridLiance West acquired Valley Electric Association’s (VEA’s) high-voltage transmission system in Clark County, Nevada along with a 230 kV transmission line project to physically connect the VEA and GridLiance transmission system to the California Independent System Operator (CAISO). Without the connection, VEA had to rely on other utilities to provide a pathway to CAISO for its transmission service needs, creating a significant risk and increasing the cost for power supply delivery for VEA’s 18,000 members. GridLiance West physically connected VEA’s transmission facilities to CAISO by building a 3.2-mile 230 kV transmission line and a 230 kV switching station. The upgrades improved the regional electric system’s reliability and resiliency in Southwest Nevada.
