Available Flexible Ramp Capacity Case 1: Flexible Ramp Sufficiency Test Pass Case 1: Flexible Ramp Capacity Constraints For T+7.5' FRC0 ≥ max(0, FRR0 − 20) = 0 FRC1 ≥ max(0, FRR1 − 30) = 0 FRC2 ≥ max(0, FRR2 − 10) = 20 FRC0 + FRC1 + FRC2 ≥ FRR0,1,2 = 85
$600, respectively. Assuming that the GHG compliance revenue is distributed to the optimal export allocations, the settlement is as follows: Resource Energy Cost GHG Compliance Cost Total Cost Energy Payment GHG Compliance Payment Total Payment G1 $5,000 - $5,000 $5,000 - $5,000 G2 $0 $0 $0 $0 $0 $0 G3 $4,200 $600 $4,800 $4,200 $600 $4,800 L1 –$10,000 L2 –$1,400 Congestion Revenue $1,600 GHG Compliance Revenue $600 It can be seen in the settlement results above that the total payment to each generator is sufficient to cover the respective energy and GHG allowance costs. Example 3 This is a variation on the second example where the available maximum capacity of G3 is reduced to 75MW in addition to reduced bid price of $28/MWh as in Example 2. In this case, G2 is dispatched to make up for the remaining 75MW and the optimal dispatch and export allocation are as follows: Resource Dispatch (MW) Export Allocation (MW) LMP ($/MWh) G1 100 - 50 G2 75 75 29 G3 75 25 29 L1 200 - 50
