A Qualified Coordinating Agency (QCA) acts as the single point of contact between the SLDC and multiple renewable energy generators connected to a shared pooling substation. The QCA coordinates aggregate day-ahead scheduling, submits intra-day revisions, and distributes net pooling deviation charges among individual generators.
Why do renewable generators appoint a Lead QCA?
When multiple solar or wind developers evacuate power through a shared transmission pooling substation, the SLDC meters only the net power injected at the high-voltage substation boundary. Because the SLDC cannot settle individual 33 kV feeder deviations separately, state regulations mandate appointing a Lead QCA to aggregate schedules and handle financial settlement with the state pool.
How should asset owners audit external QCA bills?
Asset owners should never accept aggregate monthly QCA invoices without block-by-block reconciliation. Generators should compare their internal 15-minute AMR meter data against the QCA\'s submitted schedule and the SLDC\'s published State Energy Account (SEA) to identify whether pooling penalties were allocated correctly according to the agreed pooling ratio.
REFlux includes an automated QCA auditing module that reconciles QCA statements against plant SCADA telemetry in minutes.
