Six battles  ·  ■ Demand-side   ■ Delivery-chain

1
Electron Supply
Solar + storage bypasses wholesale market. Firmed rooftop undercuts grid at ~7–8c/kWh.
Demand-side
↓ ~20% off electricity line
2
Useful Work
EV + home charging eliminates petrol spend. Vehicle ownership falls as TaaS scales across the fleet.
Demand-side
↓ $944 off petrol + vehicle
3
Useful Heat
Heat pump replaces gas at 3–4× efficiency. Gas line goes to zero for converted households.
Demand-side
↓ 100% off gas line
4
Molecule Supply
Ending NZ's $20B/yr fossil import bill. Impact is macroeconomic — flows back as lower tax burden and stronger NZD.
Demand-side
↓ Macro benefit (see note below)
5
Delivered Price
DER integration & regulatory reform cuts lines charges. Combined with battle 1, electricity falls 27%.
Delivery-chain
↓ Additional ~9% off electricity
6
Coordination Layer
Household solar/battery/EV earns VPP revenue. Net new income stream — turns cost centre into asset.
Delivery-chain
+ $420/yr new grid services revenue

Battle 4 — Molecule Supply operates at the macro level. NZ's $20B/yr fossil import bill doesn't appear on a single household's invoice, but ending it strengthens the NZD and frees fiscal headroom. Household benefit is indirect but real — estimated ~$200–400/yr equivalent.
