Advanced Energy Storage in Integrated Resource Planning: Cost Inputs and Modeling Approaches

ESA IRP PrimerAdvanced energy storage costs are declining rapidly and large-scale storage deployments are increasing. However, utility integrated resource planning does not adequately consider advanced energy storage as an option for system capacity. With utilities planning to invest billions of dollars in new and replacement capacity over the next several years, the time is now to include storage in resource planning to ensure least-cost solutions for ratepayers and prudent long-term investments for reliability.

This primer provides an overview on how to appropriately include advanced storage in long-term utility resource planning processes and includes up-to-date cost inputs from public sources.
