Common use of Compute RTO Load Served by RTO Generation Clause in Contracts

Compute RTO Load Served by RTO Generation. Using area load and losses for each load zone, compute the RTO Load, in MWs, by summing the load and losses for each load zone to determine the total zonal load for each RTO load zone. Twenty percent of RECo load shall be included in the Market Flow calculation as PJM load. See Section 6.2, of this Schedule D. __ = + , for each RTO load zone Where: zone = the relevant RTO load zone; Zonal_Total_Loadzone = the sum of the RTO’s load and transmission losses for the Loadzone = the load within the zone; and Losseszone = the transmission losses for transfers through the zone. Next, reduce the Zonal Loads by the scheduled line real-time import transaction schedules that sink in that particular load zone: __ Where: = __ − ∑ _ℎℎ_, zone = the relevant RTO load zone; scheduled_line = each of the Transmission Facilities identified in Table 1 below; Zonal_Reduced_Loadzone = the sum of the RTO’s load and transmission losses in a zone reduced by the sum of import schedules over scheduled lines to the zone; Zonal_Total_Loadzone = the sum of the RTO’s load and transmission losses for the zone; and Import_Schedulesscheduled_line,zone = import schedules over a scheduled line to a zone.
