Scenario assumptions
Source vs scenario. DMO/VDO anchors drive the official stack; iO fee, wholesale edge, CAC, churn and selected usage are scenario inputs.

Cost behaviour taxonomy
This is the usage-scaling rulebook. Every source line in the final model should carry one of these behaviour tags so we know whether it moves when kWh changes.
| Cost line | Behaviour | Scales with usage? | Calculation rule | Model note |
|---|---|---|---|---|
| Wholesale WEC | variable_per_mwh | Yes | $/MWh × MWh | Apply wholesale edge / hedge quote here. |
| Environmental schemes | variable_per_mwh | Yes | Scheme $/MWh × MWh | LRET, SRES, VEU, ESS, PDRS, REPS. |
| Network | mixed_fixed_variable | Partial | Fixed + variable × MWh | Final model should split fixed/variable/TOU. |
| Metering / smart meter | fixed_per_customer | No | $/customer/year | Pass-through or separate; avoid iO fee double-count. |
| Cost to serve | fixed_per_customer | No | $/customer/year | Core service-fee benchmark. |
| CARC | fixed_per_customer | No | $/customer/year | Exclude from iO fee if Renegade funds CAC. |
| Bad debt benchmark | fixed_per_customer | No | Regulator $/customer/year | Alternative to actual % of bill. |
| Actual bad debt | percent_of_bill | Indirect | % × bill | Scenario option. |
| Retail margin | margin_percent | Partial | % of stack / official value | Not cost-to-serve. |
| iO service fee | fixed_per_customer | No | $/month × 12 | Commercial term. |
| Actual CAC | scenario_input | No | $/customer ÷ life | Renegade assumption, not regulator CARC. |
Harmonisation bridge
Official stacks are shown first in native DMO/VDO form. This bridge shows how lines feed Renegade/iO economics.
| Official line | Harmonised bucket | Model treatment |
|---|---|---|
| Cost to serve | Service-fee benchmark | Candidate iO fee only if iO performs the function. |
| CARC | Customer acquisition/retention | Exclude from iO fee if Renegade funds CAC/retention. |
| Smart meter / metering | Metering | Pass-through or separate line; avoid double count. |
| Bad debt | Bad debt | Separate if Renegade bears actual write-offs. |
| Retail margin | Profit / merchant margin | Not cost-to-serve; must be explicit if paid to iO. |
| AEMO/NEM/ancillary/RERT | Market fees | Auditable pass-through at cost. |
