Three forces. One missing layer.
The coordination gap is not a policy choice — it is a structural consequence of building 21st-century power systems on 20th-century market architecture.
Renewables at scale
Variable generation requires temporal coordination at a granularity that wholesale markets cannot provide. Curtailment is growing because the system has no mechanism to match local surplus with local demand in real time.
Local network constraints
Binding constraints are increasingly feeder-level — below the spatial resolution of any existing market mechanism. DSOs are managing congestion through static limits and after-the-fact interventions that don't scale.
Active demand
EVs, heat pumps, and batteries are schedulable loads. Coordinating them usefully requires real-time signals that reflect local conditions — not wholesale prices that cannot see individual feeders.
