VPPs, battery plans and retailer control: what to compare
The commercial terms behind battery dispatch, tariff exposure, bill credits and customer control.
A VPP is a contract as well as technology
Check who can dispatch the battery, the reserve you keep, event limits, credits, fees, term and exit conditions.
Retail plans shape battery value
Time-of-use windows, demand charges, controlled loads, feed-in rates and wholesale exposure can materially change the result.
Do not model a benefit twice
If one operating action supports a VPP payment, demand reduction or self-consumption, the model must avoid counting the same stored energy as three separate benefits.
