Special Notes to MISO West RC / A) During this prior outage condition generation curtailment of the St. Joseph and St. Leon wind farms concurrent with TLR on MHEX_N may be required when Manitoba to USA flows are north to prevent post contingent overloads on G37C following a trip of B10T or D602F.
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 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
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.
- 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,
- The mitigation must be completed within 30 minutes.
- The MHEX_N will at all times remain below 465 MW as measured at Dorsey, Letellier, and Glenboro Stations.
- Manitoba Hydro will self-supply part of the CRSG as follows:
(415– 415) - MHEX_S MW + MHEX_N MW.
0 + MHEX_N MW.
D) Ambient Limits - For the duration of the Dorsey T52 outage, ambient temperature limits can be implemented allowing for an increase in the SCADA alarm level to a 30 deg C rating of 2983 A or 1188 MVA.
