Virtual Power Plant Companies: Who Runs VPPs in North America
By VPPdirectory · Published · Reviewed and updated · Editorial contact: Jared Theaman
Virtual power plant companies can provide aggregation services, hardware-linked enrollment, utility programs or orchestration software. Some provide more than one. Choose the service you need first, then check the provider’s current organization, program territory, contract and evidence rather than treating every VPP logo as the same product.
Which type of VPP company do you need?
| Role | Examples to research | Buyer question |
|---|---|---|
| Commercial aggregation | Voltus; CPower within NRG | Can this provider qualify my site for the required program and hold the performance obligation? |
| Residential flexibility or hardware-linked offers | Renew Home; Tesla’s utility-specific programs | Which devices, service addresses and customer agreements are eligible? |
| Utility-administered program | The actual electric utility or program sponsor | Is enrollment open for my account and equipment? |
| DERMS and orchestration software | EnergyHub and other platform vendors | Does the contract include recruitment and delivery, or only software and integration? |
These are role examples, not endorsements, a complete market census or confirmation that an offer is available at your address.
Ownership and service continuity matter
NRG’s January 2026 acquisition completion announcement provides the current ownership context for CPower. EnergyHub announced its acquisition of Resideo Grid Services in December 2025. Do not count predecessor and combined portfolios as independent fleets without checking overlap.
Sunnova’s current site says it has ceased independent operations and describes servicing by SunStrong Management. A legacy logo or old enrollment link does not establish a current independent offer. Existing customers should confirm their own system and program arrangements with the current servicer.
How should you compare company capacity claims?
- Record the measurement date, geography and unit.
- Distinguish installed equipment, enrolled or nominated capacity, managed load, event delivery and future targets.
- Identify whether the company owns the service contract or provides software for someone else’s resources.
- Check for overlaps between parent companies, acquired brands, OEM fleets and utility programs.
- Ask for deliverable capability at your site or procurement location, with duration and operating conditions.
The directory preserves those distinctions and labels missing figures as Not reported. A source-linked profile does not make every field independently verified.
Questions for a homeowner or facility manager
- Does the exact service address and device qualify?
- Who enrolls and controls the device, and who provides support?
- How are performance, backup reserves and opt-outs handled?
- What will I receive after fees, and under which payment formula?
- How do cancellation, ownership changes and other incentives affect the agreement?
Questions for utilities, OEMs and capacity buyers
- Request the named legal counterparty and division of software, recruitment and market-operation duties.
- Check current program or market qualification for the product being purchased.
- Request measured delivery from comparable events, plus gaps and lower-performance conditions.
- Examine integration, cybersecurity, data portability and continuity arrangements.
- Compare bids using the same location, hours, duration, capacity basis and customer safeguards.

Frequently asked questions
Who is the largest virtual power plant company?
The answer depends on geography, date and capacity basis. Managed load, battery export, event delivery and software-managed assets cannot be ranked as one interchangeable total.
Does a DERMS vendor sell capacity?
Some vendors also offer program services, but software alone does not establish enrolled or contracted capacity. Ask which obligations and resources the proposed contract actually includes.
How do I verify a VPP company’s MW claim?
Find a dated original disclosure, establish its capacity basis and geography, and compare it with program or market evidence for the same scope. Check overlaps and whether it is a target or historical event.
Are all directory fields independently verified?
No. Source-linked fields have cited evidence and limitations. Provider-submitted or unconfirmed claims remain labeled; they are not performance certifications.

VPP vs Demand Response: Differences and Overlap
Demand response and VPPs overlap. Compare the actual service, measurement rules and contract instead of assuming a VPP must export electricity.
