Midwest ISO will be performing system maintenance on the ASM Production Day-Ahead and Real-Time (DART) system from 0215 to 0345 EST on Sunday, August 15, 2010. There will be an associated outage of the DART web pages and XML interfaces (including outgoing XML notifications). It is anticipated that 3 to 5 UDS intervals will be missed, during this time the use of the Dispatch Target Adjustment Mode may be used. This change will not affect ICCP data. Real time updates will be sent out as needed. Midwest CRSG members may receive an error message when entering a request for ARS assistance, but the event will be processed normally within the ARS system. The error message is to indicate the event was not processed within the Midwest ISO market dispatch systems. All BAs external to Midwest ISO dispatch should adjust their NSI as per normal operation to receive or supply ARS assistance MW's. If anyone receives an error message when entering an ARS event, please contact the Midwest ISO Balancing Authority Operator to confirm that we have received the event. The Balancing Authority Operator will then be able to verify that all affected participants have acknowledged the event in the Midwest CRSG ARS application.
