Dhruv Bhatnagar and Patrick Maloney present on the deployment of long-duration energy storage (LDES) resources using a capacity expansion model to meet future clean energy needs. Using the Los Angeles Basin as an example, this presentation will show the optimized deployment of LDES to support equitable energy outcomes and the clean energy transition. The deployment of LDES will be shown in a 10-zone capacity expansion planning model from 2022–2045. The model is based on the California Public Utility Commission's RESOLVE capacity expansion model but has been modified to give greater spatial granularity in the Los Angeles Basin by adding three new subzones. Multiple scenarios will be considered to help shed light on the optimized deployment and value of LDES while considering the retirement of existing fossil fuel resources. The scenarios will explore different levels of natural gas retirements, storage costs, transmission investments, and resource availability while meeting California’s aggressive clean energy targets. Study results indicate that storage can play a significant role in helping California meet its energy requirements.
