Reconciliation Spot energy revenue = SMP × metered MWh. CfD-to-seller = (strike − SMP) × contracted MWh per contract. The matching buyer row for each contract carries the OPPOSITE sign; summing buyer.cfd_diff + seller.cfd_diff for any one contract is zero. Curtailment is compensated at SMP × 75% per the NERSA RFD 2025-04-29 ancillary service.
