MISO declares Conservative Operations for Central Region area(s) of: MIUP, WEC, WPS effective 10/27/2017 14:20 EST 

Due to transmission outages and generation derates in the Upper Penninsula area of MI and Northern WI, MISO is declaring Conservative Ops for this area. A transmission line is expected to be returned tonight. When it comes back in servic we will end this declaration.

The MISO Reliability Coordinator (RC) is declaring Conservative Operations, effective from 10/27/2017 14:20 EST to 10/27/2017 22:00 EST for the following entities: Central Region area(s) of: MIUP, WEC, WPS and instructs that:

  • All transmission and Generation maintenance is suspended in the affected area for the duration of the Conservative Operations period, unless such maintenance will result in improved Bulk Electric System (BES) monitoring, control and security.  Such maintenance will be coordinated between MISO and the applicable entity. The return to service of equipment on outage should be coordinated between MISO and the applicable entity. MISO Outage Coordination may permit on a case-by-case basis specific transmission maintenance that does not impact the Bulk Electric System. Transmission Operators (TOPs) and Generation Operators (GOPs) in the affected area, in coordination with the MISO and their Local Balancing Authority (LBA), are to review outage plans to determine whether any maintenance or testing, scheduled or being performed on any monitoring, control, transmission or generating equipment can be deferred or cancelled.
