Project Status

Project Update

The project has completed its baseline bulk system analysis and defined its preliminary grid scenarios for further analysis. The baseline analysis and preliminary scenarios were presented at a public workshop in November 2021, where attendees provided information about potential modeling sensitivities, characteristics of various energy systems, and the expected roles of hydrogen production, storage, and transport in a decarbonized grid.

The Issue

To meet California's clean-energy goals, low-cost solar and wind generation are a partial solution, but low-cost electricity is also needed when solar and wind generation are not available. While many new technologies show promise to provide the needed energy storage and demand management, their paths to market are uncertain. Modeling of California's energy systems requires extensive analysis of data including weather, geography, and the mixture of energy resources across the grid. The project's challenge is to aid in identifying which actions to take and what the timing of those actions should be by studying the roles and cost targets of storage technologies.

Project Innovation

The project is modeling the expansion of the grid using the SWITCH model and an improved version of the RESOLVE model which incorporates variable timesteps to allow full-year modeling. Modeling different grid scenarios, developed with feedback from industry experts, will help to define the role and useful cost targets for long-duration storage technologies as they are scaled to gigawatt levels.

Project Benefits

The project team will develop scenarios to reach California's clean-energy targets by updating modeling tools and analyzing broad datasets. Emerging long-duration storage technologies are expected to have a critical role in achieving a zero-carbon grid by 2045, and understanding the interaction of long-duration storage with other energy resources is an integral component of the study.
