14. Distributed Storage & FLEX: Dispatchable Availability (BTM + C&I + EV)

What this shows

  • The dispatchable share of distributed storage grows faster than total battery stock.
  • Residential, commercial, and EV batteries increasingly behave as grid assets, not passive loads.
  • Flexibility scales with enrolment, control, and coordination, not raw capacity.

Why this matters

  • Fossil peakers become obsolete
    Fast, local, dispatchable energy replaces combustion-based peak supply.
  • EVs flip from load → asset
    Managed charging and V2G turn mobility batteries into time-shifted grid support.
  • Reliability becomes a storage-coverage problem
    Location, response speed, and availability matter more than centralised nameplate capacity.
  • This is a phase change
    Once distributed FLEX reaches scale, system behaviour reorganises rather than incrementally improves.

Key terms (used in tables & charts)

  • BTM FLEX – Dispatchable residential battery energy.
  • C&I FLEX – Dispatchable commercial & industrial storage.
  • EV FLEX – EV battery energy available via smart charging or V2G.
  • Participation Rate – Share of assets enrolled and controllable.
  • Distributed FLEX – Available, dispatchable energy only (not nameplate capacity).

Note: Distributed FLEX reflects availability, depth-of-discharge limits, participation rates, and grid constraints — not theoretical capacity.
