Curtailment and Missed Revenue, by Cause
See how much energy each wind and solar unit could have generated and was not dispatched, why, and what that cost at the regional price: network, economic or unknown, with the evidence behind every cause.

Revenue Truth at the Connection Point
Missed revenue values curtailed energy at the regional reference price of each 5-minute dispatch interval. Pair it with loss-factor unit revenue (via API) and you have both sides of what a connection point earns.
Every Megawatt-Hour Has a Stated Cause
Curtailment is the market operator's unconstrained forecast for the unit minus the energy it was dispatched. Network Map then proves the cause from the market operator's own records: a binding constraint on the unit (network), a regional price below the unit's offer (economic), or neither provable (unknown).
Live Total: All Regions
204 semi-scheduled units across five regions. Missed revenue is valued at the regional reference price for each curtailed five-minute interval. Economic curtailment mostly happens at negative prices, so its value is negative: a cost avoided.
