California’s limited electrical transmission system is generating concern lately as clean energy projects outpace planning and construction of infrastructure needed to carry that power to cities.

A recent report by the organization that runs the state’s power grid, California Independent System Operator, or CAISO, says 46 transmission projects will be needed to serve large investments in solar, wind and energy storage it deems necessary to meeting the state’s goal of achieving carbon neutrality by 2045.
