A) During this prior outage condition generation curtailment of the St. Joseph and St. Special Notes Leon wind farms concurrent with TLR on MHEX_N may be required when to MISO West Manitoba to USA flows are north to prevent post contingent overloads on G37C RC following a trip of B10T or M602F.
B) The SOL for MHEX_S and MHEX_ N is the same if the MISO RTCA and MISO Flowgate Monitoring Tool is unavailable prior to or during this outage.

Special A) TOI Extentions - This TOI may be extended until 23:59 by performing the following Instructions to steps: MHEB 1. Verify system conditions to confirm there are no additional tie line facilities Operator: outages, or new internal MH outages. 2. Review RTCA to confirm there are no new contingencies. 3. 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. 4. Extend the outage in COLA. 5. Update TLAP outage table. 6. Provide notice to affected balancing authorities
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.
C) For MHEX_N: The MHEX_N will at all times remain below 285 MW as measured at Dorsey, Letellier, and Glenboro Stations. Manitoba Hydro will self-supply part of the CRSG as follows: Self-Supply > (CRSG - NonFirm) - MHEX_S MW + MHEX_N MW. > (320– 320) - MHEX_S MW + MHEX_N MW. > 0 + MHEX_N MW
Special D) AGC Control – Treat as system intact. Instructions to - MISO RC will monitor R50M and adjust AGC as necessary. MHEB Operator - Identify MHEX SOL with remaining MHEX Tie lines in-service excluding R50M. (cont):
