Virtual Power Plants in CAISO
California Independent System Operator
CAISO allows demand-response providers to aggregate customers and participate in day-ahead, real-time, and ancillary-services markets when the resource meets the applicable market requirements.
How flexibility reaches CAISO
The participation model matters. Proxy Demand Resource, Reliability Demand Response Resource, Distributed Energy Resource Provider, storage, and load-shift pathways have different registration, metering, telemetry, bidding, and operating requirements.
A wholesale CAISO resource typically needs a scheduling coordinator and revenue-quality metering, with additional certification or direct telemetry for some services. California also has utility and state reliability programs outside the wholesale market, so buyers should confirm whether a provider is proposing CAISO participation, a retail program, or a combination that permits dual participation.
What buyers should compare
Participation model
Identify whether the resource will use PDR, RDRR, DER Provider, storage, load-shift, or a retail program. Each model supports a different operating and settlement profile.
Metering and baselines
Confirm interval data, baseline methodology, revenue-quality metering, telemetry, and scheduling-coordinator responsibilities before relying on projected market value.
Wholesale versus retail
California utility and state programs can be distinct from CAISO market participation. Verify dispatch priority, dual-enrollment restrictions, and who controls the asset during overlapping events.

CAISO VPP questions
How can aggregated demand response participate in CAISO?
Qualified providers can aggregate customer load and use an applicable CAISO participation model to bid flexibility into day-ahead, real-time, or ancillary-services markets, subject to registration and operating requirements.
Are California utility programs the same as CAISO participation?
No. Utility and state reliability programs may operate outside the wholesale market. A provider may participate in one or both, but eligibility and dual-enrollment rules must be checked for the specific program and asset.
Is the capacity shown here committed to CAISO?
No. It is the full published portfolio capacity of providers associated with CAISO. Ask providers for currently enrolled, deliverable, and contractable MW for the relevant utility territory and product.
