VPP payment scenario calculator
Estimate a payment for one named program, territory and period. Summer capacity rates and emergency-event energy rates measure different things. Select one scenario; alternative utility rates are never added together.

CPUC-published nonresidential rate only. Utility, subgroup, baseline and current enrollment eligibility must be confirmed.

Example inputs are illustrations, not typical earnings, a dispatch forecast or hardware specifications.
Power committed after reserve settings; not an entire fleet or solar nameplate.
Available qualifying reduction per event. The model caps this at power × event hours.
Your scenario duration; ELRP illustration caps event duration at 5 hours and modeled dispatch at 60 total hours.
Your assumption, not a prediction. No events means no event payment.
Fraction credited after availability and measurement assumptions. Actual settlement uses the approved baseline.
What does this estimate mean?
This is an illustrative program payment before charging costs, equipment costs, taxes and other fees. It is not net profit, a quote, an eligibility decision or a multi-year promise. Installation rebates, winter products and other programs are excluded.
Confirm the current utility territory, enrollment, performance baseline, payment caps and provider agreement before relying on a result. Program rules and rates can change.
