Three revenue layers beyond self-supply:
1. Self-supply first — avoid buying the most expensive grid kWh 2. Feed-in / net billing — metros like City of Cape Town pay for surplus (indicative ~R1/kWh; confirm current tariff schedule) 3. Wheeling & wholesale — from 2026, move energy to other sites or trade on competitive markets
Battery storage maximises export value by shifting surplus to peak price windows. Masibambane's managed platform optimises against live tariffs post-commissioning.
