B) The SOL for MHEX_S is 1990 MW and MHEX_ N is 630 MW if the MISO RTCA and MISO Flowgate Monitoring Tool is unavailable prior to or during this outage. Special Instructions to MHEB Operator:A) TOI Extentions - This TOI may be extended until 23:59 by performing the following steps: Verify system conditions to confirm there are no additional tie line facilities outages, or new internal MH outages. Review RTCA to confirm there are no new contingencies. Contact MISO to confirm there are no new outages, if there are no new outages provide notice to MISO that MH is extending the TOI. Extend the outage in COLA. Update TLAP outage table. Provide notice to affected balancing authorities Special Instructions to MHEB Operator (cont):B) When called upon by MISO for the supply of CRSG: If Real Time Contingency Analysis (RTCA) indicates a post contingent overload condition on Y51L for the contingent loss of D14S - redispatch MH generation to maintain CRSG delivery as per: Start Brandon Gas Generation and run up to 60 MW. Brandon generation must be re-dispatched from HVDC generation at Dorsey After 60 MW re-dispatch is complete, should RTCA continues to indicate a post contingent overload condition on Y51L due to the contingent loss of D14S, Continue to re-dispatch generation from Brandon gas in 10 MW increments until post contingent overload on Y51L has been mitigated. The mitigation must be completed within 30 minutes. Prepared By:P. GrestoniDate:2017 12 07Revised By:P.
