Common use of Calculating the Expected Impact of the PARs at the Michigan-Ontario Border on Market Flows Clause in Contracts

Calculating the Expected Impact of the PARs at the Michigan-Ontario Border on Market Flows. The Non-Monitoring RTO’s unadjusted Market Flow is determined as RTO_MF in accordance with the calculation set forth in Section 5 above. The expected impact of the PARs at the Michigan-Ontario border is determined as follows: Where: M2M_Flowgate-m = the relevant M2M Flowgate; MICH-OH Path = each of the four PAR paths connecting Michigan to Ontario, Canada; MICH-OH_PAR_ImpactM2M_Flowgate-m = the expected impact of the operation of the PARs at the Michigan-Ontario border on the flow on M2M Flowgate m; PSF(MICH-OH Path,M2M_Flowgate-m) = the PSF of each of the four Michigan-Ontario PAR paths on M2M Flowgate m; RTO_MFMICH-OH Path = the Market Flow for each of the four Michigan-Ontario PAR paths, computed in the same manner as the Market Flow is computed for M2M Flowgates in Section 5 above; and LEC = Actual circulation around Lake Erie as measured by each RTO. The Non-Monitoring RTO’s LEC Adjusted Market Flow, reflecting the expected impact of the PARs on the Michigan-Ontario border, can be determined by adjusting the RTO_MF from Section 5 to incorporate the MICH-OH_PAR_Impact calculated above. Where: M2M_Flowgate-m = the relevant flowgate; MICH-OH Path = each of the four PAR paths connecting Michigan to Ontario, Canada; MICH-OH_PAR_ImpactM2M_Flowgate-m = the expected impact of the operation of the PARs at the Michigan-Ontario border on the flow on M2M Flowgate m; RTO_MFM2M_Flowgate-m = the Market Flow caused by RTO generation dispatch and transaction scheduling on M2M Flowgate m after accounting for the operation of both the common and non-common PARs; and LEC Adjusted Market FlowM2M_Flowgate-m = the Market Flow caused by RTO generation dispatch and transaction scheduling on M2M Flowgate m after accounting for the operation of the common PARs, the non-common PARs, and the PARs at the Michigan-Ontario border.
