Working Groups

CESA has 25 unique and active working groups, which provide members receive real-time insights on market, policy and regulatory developments. These collaborative, subject-specific working groups enable members to shape CESA positions on the issues that matter most to them.

Building Energy Efficiency Standards

Support proper valuation of storage in new building energy efficiency requirements, which will soon include onsite solar integration.

Bulk Storage

Ensure a level playing field and potential procurement pathways for bulk storage and infrastructure-size storage resources like Compressed Air Energy Storage (CAES) and Pump-Hydro Energy Storage.

Demand Response (DR)

Develop participation models, auction mechanisms, and programs that fairly value fast-response and dispatchable energy storage enabled DR, as well as to develop performance evaluation methodologies and enable multiple-use applications for energy storage.

Distribution Resources Plans (DRP) & Integrated Distributed Energy Resources (IDER)

Advance the valuation, sourcing, and use of distributed energy resources (DERs), such as energy storage, to support utility distribution grid and reduce distribution system upgrade costs.

Electric Vehicles (EV)

Provide pathways to value or direct smart EV charging and EV-related rates, and explore synergies of EV charging infrastructure and energy storage in the state’s transportation electrification efforts.

Emerging Technologies & Long-Duration Storage

Identify solutions to barriers impeding the development of emerging and long-duration energy storage technologies, applications, and business models, including financing, experience requirements, and special opportunities.

Energy Storage & Distributed Energy Resources (ESDER) Initiative

Drive value and creates pathways for storage and aggregated DERs to participate in the wholesale markets.

Energy Storage Rulemaking

Address myriad energy storage procurement approaches and issues, including energy storage technology definitions, special procurements, etc.

Federal Energy Regulatory Commission (FERC)

Address FERC policy and issues related to energy storage or California policy.

Frequency Response & Regulation

Appropriately value the benefits of fast-responding resources like energy storage through proper frequency response market designs.

Integrated Distributed Energy Resources (IDER)

Inform California’s bi-annual grid and energy policy planning and forecasting efforts at the California Energy Commission.

Integrated Resource Plans (IRP)

Boost consideration and study of energy storage in integrated system planning to optimize grid planning to achieve the renewables, environmental and grid reliability objectives.

Legislation (Board Members Only)

Determines and directs legislative priorities and advocacy at the California Legislature and Governor’s Office, including bills that CESA supports, sponsors, opposes, or shapes. Contact us to join the CESA Board.

Rate & Tariff Design: Net Energy Metering (NEM), Time of Use (TOU)

Formulate policy recommendations in specific rate design proceedings to enable appropriate price signals for and enable valuation of benefits of customer-sited energy storage.


Ensure smart policy approaches to grid planning for both in-state and out of state (regional) resources and grid management.

Renewable Portfolio Standard (RPS)

Build or expand roles for energy storage to support or ‘pair’ with renewable resources like wind or solar, as California pursues a 100% zero-carbon generation goal by 2045 and 60% RPS by 2030.

Resource Adequacy (RA)

Framework to ensure grid and operational needs are met and appropriately value high-performance resources like energy storage.

Rule 21 Interconnection

Streamline interconnection processes and minimizes interconnection study costs for utility distribution (retail) interconnections.


Address safety issues and related codes, standards and regulations for energy storage.

Self-Generation Incentive Program (SGIP)

Shape program design and requirements for California’s $1B customer-sited energy storage incentive program.

Storage as Transmission Asset (SATA)

Clarify agreements and opportunities for energy storage to provide transmission reliability services while also reducing costs to ratepayers by providing wholesale energy market services.

Transmission Planning Process (TPP)

Advocate for the consideration of non-wires transmission alternatives, including energy storage, to address transmission needs identified in annual reliability, economic, and policy studies.

Wholesale Interconnection

Improve interconnection processes for utility-scale energy storage resources, including generation-paired resources.
