CAISO Sees Little Need for New Transmission

Citing the lack of additional need for any policy driven projects to be approved at the present time to achieve the state’s Renewable Portfolio Standard goal of 60 percent by 2030, the California Independent System Operator approved nine transmission projects at an estimated cost of $141.7 million as being essential for maintaining reliability of the ISO transmission system.

Of this year’s projects, seven are located in Pacific Gas & Electric’s service territory at an estimated cost of $120.7 million. The other two projects are located within the Valley Electric Association/GridLiance West and Southern California Edison service territories at an estimated cost of $21 million.

The 2019-2020 Transmission Plan assesses  the transmission needs of the electric system over a 10-year period. To arrive at the recommended projects, the grid was analyzed over the past 15 months to identify upgrades needed to meet reliability needs, California’s policy goals, and transmission projects that can bring economic benefits to consumers.
