On October 23, 2026, the California Energy Commission (CEC) released GFO-26-503, a competitive grant solicitation under the Distributed Electricity Backup Assets (DEBA) program, titled "Distributed Energy Resources (DERs) for Grid Reliability." It is the first DEBA round funded by Proposition 4, the $10 billion climate bond voters approved in November 2024. The goal is to pay for new, zero-emission distributed resources that add supply, or reduce or shift demand, when California's grid is under stress during heat waves, wildfires and other extreme events.
The solicitation page lists funding of "up to $46,144,000." That figure overstates what most applicants are competing for. The CEC is also running a separate, non-competitive direct-award process for water utility projects, and state law requires part of the same money to go there. The competitive pool is therefore likely to be between $23 million and $34 million, enough for a few large projects or about a dozen mid-sized ones.

The actual size of the competitive pool
SB 105 (Chapter 104, Statutes of 2025) appropriated $46.1 million in Prop 4 money to DEBA. It also requires that at least $12.5 million of that amount "shall provide state cost sharing for water utility projects that have received awards from the United States Department of Energy Grid Resilience and Innovation Partnerships program," and allows the CEC to award those funds "expeditiously and non-competitively."
In a June 16, 2026 announcement, the CEC said it planned to set aside $12.5 million to $23 million for these GRIP water utility direct awards, with whatever remains going to the competitive solicitation. Letters of interest from GRIP awardees were due July 6, 2026.
The resulting range:
| Water utility set-aside | Competitive pool | Awards at $8M max | Awards at $2M min |
|---|---|---|---|
| $12.5 million (statutory floor) | about $33.6 million | about 4 | about 16 |
| $23 million (CEC's upper estimate) | about $23.1 million | about 2 to 3 | about 11 |
A third-party listing shows an anticipated range of $23.144 million to $46.144 million, which matches a $23 million set-aside at the low end. Because the statute requires at least $12.5 million for water utility cost-share, $46.1 million cannot all be competitive. Plan for a pool of about $23 million to $34 million. Applicants should ask at the November 5 workshop how much was committed through the GRIP process.
What DEBA is for
DEBA was created by AB 205 (2022) as part of California's Strategic Reliability Reserve, the state's response to the August 2020 rotating outages and the September 2022 heat wave that brought the grid close to blackouts. The program is codified in Public Resources Code Sections 25791 and 25791.5. It is meant to pay for "cleaner and more efficient distributed energy assets" that act as on-call emergency supply or load reduction during extreme events.
The CEC adopted the first DEBA Program Guidelines on October 18, 2023. The first solicitation, GFO-23-401 (Bulk Grid Asset Enhancements for Grid Reliability), issued a notice of proposed award on April 22, 2024. That round focused on efficiency upgrades and capacity additions at existing generators. GFO-26-503 is different. It funds only new, zero-emission distributed resources.
What the solicitation funds
From the solicitation materials and listings, eligible projects must:
- Deploy new, commercially available, zero-emission resources: energy storage, load-flexibility controls, distributed generation and microgrid equipment.
- Serve non-residential customers or aggregated residential customers in California. A single home battery does not qualify. An aggregator's virtual power plant of home batteries could.
- Add capacity that is incremental to existing Resource Adequacy (RA) and Strategic Reliability Reserve resources. Capacity already counted toward a load-serving entity's RA obligation, or already paid for by another reserve program, does not qualify.
- Dispatch and report for at least three program seasons, responding to reliability needs through a performance pathway the applicant selects.
The application package shows what the CEC will check. Beyond the usual narrative, scope of work, schedule, budget and team forms, it includes a CEQA compliance form, a measurement and verification (M&V) plan, a project readiness checklist, commitment and support letters, and a past projects form. The CEC will weigh readiness and verifiable performance heavily.
Eligible applicants, per listings, include public agencies, tribes, utilities, nonprofits, institutions and businesses. Confirm eligibility in the solicitation manual (document 00 in the ECAMS package) before committing to a project.
Who has an advantage
Aggregators and DER providers with existing customer portfolios. Aggregated residential and commercial resources are explicitly eligible. A company that already manages thermostats, batteries or EV chargers for thousands of customers can propose a new enrolled fleet that reaches $2 million to $8 million in scale faster than a single-site developer.
Public agencies with critical facilities. Water and wastewater districts, school districts, fire stations and county buildings already need backup power. A battery or microgrid that serves the facility's resilience needs and also dispatches to the grid during emergencies offers two benefits for one grant. Remember that water utility projects with GRIP awards have their own direct-award track and may not need to compete here.
Tribes. Tribal microgrids often face the worst outage exposure and have clear CEQA paths on trust land. They are listed among eligible applicants.
Projects with construction-ready status. A three-season dispatch requirement means the CEC wants capacity online by a known summer. Projects with interconnection applications filed, sites secured and equipment specified will score better on readiness than concept-stage proposals.
Five things to settle before January 26
1. Prove additionality. The most common reason a reliability proposal fails is double counting. Write down where every kilowatt goes: not under an RA contract, not enrolled in the Demand Side Grid Support program or the Emergency Load Reduction Program, not already counted by a utility. If an existing customer program covers the same load, explain why the DEBA capacity is new.
2. Choose the performance pathway carefully. The solicitation requires a selected pathway for responding to reliability needs. Weigh how often the resource will be called and for how long against what customers will tolerate. A battery fleet that can deliver four hours on the hottest evening is worth more than one that can deliver one hour.
3. Build the M&V plan first. Three seasons of dispatch and reporting means the CEC will measure actual performance against a baseline. Metering, telemetry and baseline methods for aggregated loads are technically hard. Write the M&V plan before the narrative, and cite proven methods.
4. Clear CEQA early. Most storage and controls projects will fit a categorical exemption, but ground-mounted generation or new microgrid structures may need more. Have the lead agency identified and its determination underway before submission.
5. Get the commitment letters. Site hosts, aggregated customers' program agreements, utility interconnection contacts and local governments all take time to produce letters. Start in November.
Timeline and risks
- November 5 workshop. Attend. The CEC typically answers questions there about scoring, eligibility and the GRIP set-aside, and the answers become part of the record.
- November 13 questions deadline. Submit any eligibility questions in writing. Written answers are binding.
- January 26, 2027. Submit through ECAMS. Create an account now; first-time registration is slow.
- Budget risk. Prop 4 money is appropriated, but California's budget has been tight. Bond-funded climate programs have seen amounts shift between budget acts, and AB 113 (2026) already touches this solicitation's authority. Watch the January 2027 Governor's budget proposal.
- Delivery risk. Battery and transformer supply chains, interconnection queues and utility upgrade timelines can delay energization. A three-season obligation that starts late puts the award at risk.
The bottom line
GFO-26-503 is a small, focused grid-reliability program. With the water utility set-aside, about $23 million to $34 million is available competitively, in grants of $2 million to $8 million, for new zero-emission storage, load flexibility, distributed generation and microgrids that are additional to existing reliability resources and can commit to at least three seasons of dispatch.
The winning applications will likely be from aggregators with ready customer fleets, public agencies and tribes with backup-power needs and construction-ready sites, and any applicant that can measure and verify what it delivers. Attend the November 5 workshop, send questions by November 13, and submit by January 26.
