FERC Order 2222 Explained: What It Means for VPPs in 2026
By VPPdirectory · Published · Reviewed and updated · Editorial contact: Jared Theaman
FERC Order 2222 directs the RTOs and ISOs it covers to enable distributed energy resource aggregations in wholesale markets. It does not make every device immediately eligible or remove distribution-utility review. The participation model, implementation date, location and service qualification still determine the route to market.
What does Order 2222 require?
- Create a participation route for qualifying DER aggregations, including combinations of resource types.
- Set an aggregation minimum-size requirement no higher than 100 kW; that is not a requirement that each device be 100 kW.
- Define location, data, metering, telemetry and coordination rules.
- Address retail/wholesale co-participation and duplicate compensation.
FERC’s explainer summarizes the rule; the orders, accepted tariff and applicable retail/distribution rules control a specific application. The rule does not itself certify any provider’s fleet or promised revenue.

Market status: reviewed October 21, 2026
| Market | What the reviewed material establishes | Buyer implication |
|---|---|---|
| CAISO | FERC’s explainer identifies Order 2222 implementation as complete as of November 2024 | Choose the applicable model and confirm current resource qualification |
| NYISO | An operating DER and Aggregation Participation Model has onboarding and participation rules | Existing operation does not make every resource or retail combination eligible |
| ISO New England | The participant-readiness page gives November 1, 2026 as the new model’s effective date | As of this review it is upcoming; existing DER participation options are separate |
| PJM | The fact sheet distinguishes 2028/2029 capacity participation and the full energy/ancillary model expected February 2028 | Do not describe full Order 2222 energy participation as already live |
| MISO and SPP | The cited filings describe phased or proposed implementation | Check the latest operator milestones and accepted tariff before relying on a date |
| ERCOT | A separate Texas ADER pilot | Not an Order 2222 implementation market |
This table is a dated research guide, not a registration decision. The FERC explainer’s timeline section contains older milestones, so newer operator readiness material is used where available. Auction dates, delivery years and software effective dates are different events.

Why utility coordination still matters
An aggregation must respect distribution reliability, resource location and operating permissions. Market acceptance does not automatically change an interconnection agreement or authorize new export. Retail programs may also impose co-participation and consent requirements.
Before building a fleet, establish which party coordinates the utility review, supplies authoritative meter data and resolves changes to participating devices. Do not infer approval from a device’s protocol certification.
Section sources
What should an aggregator or capacity buyer request?
- The exact participation model and services the resource is qualified to provide.
- The legal market participant and registration or application evidence.
- A clear distinction between a proposed milestone and a live operating permission.
- Utility review, interconnection and retail-program compatibility for the same resources.
- Approved telemetry, metering, measurement and settlement arrangements.
- Evidence of performance and contractual responsibility for shortfall.
How does Texas differ?
Order 2222 does not apply to the ERCOT area. ERCOT’s ADER pilot has its own governing documents, registration and qualification process. Do not extend that exception to every electricity system located in the state of Texas, and do not treat pilot participation as a general household enrollment offer.

Frequently asked questions
What is FERC Order 2222 in simple terms?
It directs the covered regional wholesale grid markets to make room for groups of distributed energy resources to participate. Each market’s implementation, tariff and technical qualifications still apply.
Does each DER need to be at least 100 kW?
No. The order requires the market’s minimum aggregation-size threshold to be no greater than 100 kW. Individual resources and the aggregation still have other eligibility conditions.
Is the new ISO New England DER model live on October 21, 2026?
The reviewed readiness page gives an effective date of November 1, 2026. Existing DER participation options are distinct from that upcoming implementation.
Does Order 2222 apply to ERCOT?
No. The ERCOT area follows a separate Texas ADER pilot and market framework.
Can I enroll without my utility’s involvement?
Do not assume so. Distribution reliability review, metering, interconnection and retail-program rules can still apply to an aggregation.
