MISO will be performing system maintenance on the ASM Production Day-Ahead and Real-Time (DART) system from 09/14/2017 16:30 EST to 09/14/2017 17:00 EST. We expect 3 to 5 Unit Dispatch System (UDS) intervals will be missed and outbound set-points will have a short interruption. During this time the use of the Dispatch Target Adjustment Mode may be directed by MISO. During this window, there will be two associated outages of the Portal web pages: Extensible Markup Language (XML), interfaces (including outgoing XML notifications) and Real Time Offer (RTOE) overrides submitted directly via the Market Portal or API.
Market participants are NOT to switch to XML unless otherwise notified.
The MISO Shift Manager will send real time updates and additional information, if necessary.
