From Passive Buildings to Power Plants
A virtual power plant (VPP) aggregates dozens or hundreds of small energy assets — rooftop solar, batteries, EV chargers — into a single dispatchable resource that utilities pay for. Apartment buildings were long written off as unable to participate; the new economics change that. Research from Australia's apartment VPP pilots uses cooperative game theory to allocate profits fairly among residents, ensuring every unit that contributes gets a share of the revenue.
The Shared-Infrastructure Model
The winning architecture is a shared 30kWp PV array with a single meter, software that routes surplus solar from low-usage units directly to high-usage neighbors before the building ever buys from the grid, and batteries that capture the rest. Utilities increasingly reward this with capacity payments — the Strata VPP pilots show a 39.4% return on investment over a 10.5-year horizon. The result: landlords cut common-area power bills, tenants get cheaper electricity, and the grid gets clean dispatchable capacity without building a power plant.
