Certificate counts are computed from the model's registered performance data using the current regulated equations. A lodged claim depends on the specific installation, household size, and the scheme rules in force at creation. Energy savings % is against the AS/NZS 4234:2021 reference electric storage water heater for that zone and load size, calculated from the model's registered performance data, or taken directly from the register where it publishes a savings figure. VEU registers this data at the small load (the step-down load for a medium-rated system) and ESS at the medium load, so the two schemes' figures differ for the same zone.
