CESA
DELIVERS TOP-TIER STAKEHOLDER ENGAGEMENT
To execute our mission, CESA ensures that member interests are represented and appropriately considered in the key forums shaping California’s electric grid:
CESA channels your feedback and delivers regulatory advocacy through seven Working Groups:
The SAFETY & PERMITTING WORKING GROUP convenes CESA members and stakeholders to advance best practices for energy storage safety, system design and siting and permitting. The group tracks updates to fire codes, safety standards, and research developments, while coordinating industry input into regulatory and code-development processes. Its work helps ensure safe deployment of storage technologies while supporting continued market growth. The group also tracks and engages in land use and permitting topics related to storage, including local ordinance development and zoning code updates.
The CALIFORNIA INDEPENDENT SYSTEM OPERATOR (CAISO) WORKING GROUP engages in wholesale market design and operational rules that shape how energy storage participates in California and across the West’s grid. Members collaborate to improve market modeling of storage operations, ensure markets reflect real-time opportunity costs energy storage resources face, and address issues such as uplift payments, hybrid participation, and state-ofcharge management. These efforts help ensure storage resources are efficiently dispatched and fairly compensated in CAISO markets.
The RESOURCE ADEQUACY (RA) WORKING GROUP focuses on California’s capacity planning framework and policies that determine how storage resources contribute to grid reliability. Members engage on reforms to capacity accreditation, resource availability rules, and procurement structures at both CAISO and CPUC. Key topics include hybrid capacity methodologies, hourly capacity frameworks, and long-duration storage accreditation, all of which directly influence the value and role of storage in meeting reliability requirements.
The INTEGRATED RESOURCE PLANS (IRP) WORKING GROUP engages in California’s long-term planning process to ensure energy storage capabilities are accurately reflected in system modeling and procurement decisions. Members review modeling assumptions, resource valuation methods, and planning scenarios that determine least-cost portfolios for meeting reliability, emissions, and clean energy goals. This work helps ensure that storage resources are appropriately considered and valued in future grid planning and procurement strategies.
The EMERGING TECHNOLOGIES & LONG-DURATION STORAGE WORKING GROUP explores policy pathways and market opportunities for next-generation energy storage technologies, including long-duration energy storage (LDES). The group evaluates procurement frameworks, funding opportunities, and regulatory developments that can accelerate commercialization and grid integration of emerging storage technologies. Note: This working group is currently merged with the IRP working group.
The DISTRIBUTED ENERGY RESOURCES (DER) WORKING GROUP advocates for policies and programs that expand deployment and compensation opportunities for distribution-connected storage, spanning both front-of-meter and behind-the-meter systems. The group works to improve interconnection processes and strengthen demand response frameworks. It also pursues funding for distributed energy programs and works to reduce unnecessary regulatory burdens on distributed storage resources.
The LEGISLATION WORKING GROUP (BOARD MEMBERS ONLY) enables CESA Board Members to guide the organization’s legislative strategy and policy priorities. Working with CESA staff and Sacramento lobbyists, the group evaluates proposed legislation, develops advocacy strategies, and educates policymakers about the value of energy storage in supporting California’s reliability and clean energy goals.

GENERAL BOARD
ADVOCACY THAT YIELDS RESULTS
GROW
CESA secured a 2 GW long-duration energy storage (LDES) procurement order from the CPUC, facilitating the Department of Water Resources’ central procurement. The CPUC also authorized investor-owned utilities to procure their share of the 3.8 GW of LDES needed by 2035.
CESA organized a webinar for LDES members, attracting 240 attendees from the California Community Choice Association and California Municipal Utilities Association, showcasing industry collaboration and innovation.
CESA’S POLICY WORK
CESA has established grid-connected storage as a primary focus for policy development in California and beyond. Through continuous engagement with policymakers, CESA ensures that the critical role of energy storage in optimizing the electric power system is widely recognized and understood.
ADVOCATE
CESA defeated bills that would have mandated excessive safety requirements and worked closely with the Legislature to pass Senate Bill 283, which requires project developers to collaborate with local fire departments on the design and commissioning of energy storage systems.
CESA successfully advocated for the removal of the $1K bid cap on energy storage resources at CAISO, allowing bidding up to the market cap of $2K.
SHAPE
CESA promotes improvements to market participation and modeling of energy storage resources within CAISO’s Energy Storage Enhancements (ESE) initiative, advocating for efficient pricing and optimization of storage assets.
In addition, CESA represents the industry to resist local moratoriums and restrictions on Battery Energy Storage System (BESS) development, fostering a supportive regulatory environment.
