For MRTU launch the limit will be set so that the total energy scheduled in the IFM and RUC will be no greater than 99% of the RUC target unless this limit is relaxed in the RUC scheduling run. 250 0 Limit on quick-start capacity Limits the amount of quick-start capacity scheduled in RUC (resources that can be started up and on-line within 5 hours) that can be scheduled in RUC. For MRTU launch the limit will be set to 75%. 250 0 Day-Ahead energy schedules These values preserve schedules established resulting from the IFM run in IFM in both the RUC scheduling run and pricing run.
