California could need 55GW of long-duration storage by 2045
Earlier this year Californian regulators floated an interim requirement for 1GW of long duration storage by 2026. Now a new study by California Energy Storage Alliance (CESA) has suggested that this could be a substantial under-assessment. Its study suggests that the state could need 11GW by 2030 and 45-55GW by 2045. The CESA study concluded that because of the magnitude of the resource build out, it’s important that the state start procuring long-duration storage now in order to reach its 2045 goal. It used the GridPath model which allows sequential modelling of each hour of each year which pointed out...
