It is now widely recognized that solar + energy storage, including long-duration energy storage, will be critical to achieve deep decarbonization. California already leads the nation in solar deployment and is establishing a lead in long-duration storage with the recent approval of $140 million for energy storage projects in the 2022-2023 state budget. However, even with significant funding, obstacles to the deployment of storage projects and decarbonization persist. This panel will explore the perspectives of regulators, developers, utilities and large commercial energy users on what is needed to unlock rapid deployment of energy storage and deliver the decarbonized energy future.
