Public beta
A directory built for discovery, with evidence visible at the claim level.
VPP data is unusually easy to overstate because deployed assets, enrolled load, event output, software-managed portfolios, forecasts, and targets are often described with the same MW unit. We preserve those distinctions instead of presenting one misleading total.
Entity taxonomy
Every profile is classified as an aggregator/operator, software platform, utility program, market resource, or watchlist entry. Customer segment is tracked separately.
Field-level evidence
Capacity, status, service territory, and markets each receive an outcome: Supported, Mismatch, Needs primary source, or Not audited. Each field shows its checked date and claim-specific source when available.
Capacity basis
Peak dispatchable
Reported peak capability for a stated portfolio and period; individual measured event results have a separate basis.
Event performance
Measured load shift or output during a particular grid event.
Enrolled program
Nameplate or qualified capacity enrolled in a utility or market program.
Nominated capacity
Capacity submitted or nominated for market participation.
Managed portfolio
Flexible load or DERs managed by a platform across programs and markets.
Installed portfolio
Installed equipment; not assumed to be dispatchable VPP capacity.
Market-wide registered
A whole-market resource category, not one provider's portfolio.
Announced target
A future goal or approved ceiling, not operating capacity.
Rollup and ranking rules
- Only primary-source-supported capacity in active or pilot listings is eligible.
- Only the same entity type and capacity basis may be compared.
- Planned targets, acquired records, market-wide resources, installed portfolios, and unsupported claims are excluded.
- Known parent/subsidiary and program overlaps are not double counted.
Audit coverage
The current directory contains 51 profiles. The October 21, 2026 review covered the remaining profiles’ descriptions, operating status, documented location subsets and market claims. Capacity retains its own claim-specific source and checked date; the broader review does not reverify every capacity figure. A supported field does not certify the whole profile.

Lawrence Berkeley National Laboratory’s January 2025 VPP research is an external coverage reference. It describes roughly 180 VPP programs within a broader inventory of demand-response and related programs. It is a dated research reference, not validation of this directory or evidence that every program is currently open. Our documented state subsets are not a census of U.S. VPP availability.
