August 26, 2024--Written by John Egan for Industrial Info Resources (Sugar Land, Texas)--California's transmission grid manager has sharply increased its estimate of investment in transmission assets needed in the state over the next 20 years. To comply with state law mandating that 100% of electricity delivered in the state come from renewable and zero-carbon resources by 2045, the California Independent System Operator (CAISO) (Folsom, California), in a July 31 study, projected that $45.8 billion to $63.2 billion of new transmission investments would be needed in the state over the next 20 years.
