1 Modeling the Value of Energy Storage StorageVET Demonstration Giovanni Damato Technical Leader CESA Webinar

2 Agenda 1) Overview of StorageVET (30min) 2) StorageVET Demo (30min) 3) Open Discussion (30min) 2

3 Objectives 1) StorageVET V1.0 is live and available to the public for free at 2) Success will be measured through its practical application, continued stakeholder engagement, and refinement 3) StorageVET industry support to ensure that all technologies and energy storage use cases are adequately represented 3

4 4 Important Uses for Storage Valuation Finding Opportunities: How can storage be used to address critical needs? Batteries as peaker replacements Deferring wires investments Integrating renewables Are these solutions better than conventional options? Customizing and Comparing Projects: How do we choose and justify storage projects for maximum value? Use Case Location Sizing Technology Storage Operations: How do we optimize without negative side effects? Prioritizing compatible service combinations Conforming to interconnection constraints Considering degradation and unique technology attributes in dispatch decisions

5 Challenges to Modeling Storage Storage and limited energy resources are still not common Rules and regulations still are evolving Benefit stacking is appealing, but will it be possible More services = more value More services = more requirements Can they be satisfied? Locational value of storage requires site-specific analysis Complex optimization between storage degradation and service participation scheduling 5

6 StorageVET Storage Value Estimation Tool: Web-hosted tool, free to the public Project cost-benefit analysis Time-series dispatch optimization simulation Stacked services Customizable for location, sizing, use cases Initial California data and definition customization StorageVET Goals Accessible Transparent Validated Customizable 6
