Urgent Market Messages (UMMs) contain planned and unplanned unavailability for power generating, consumption and storage units of any size, including their history of the last 5 years. Limitations of at least 10 MW lasting for 15 minutes or more can be reported.

All messages are published immediately (in UTC time format) and can be updated on an on-going basis. Planned and unplanned unavailability from the past 365 days including their entire history are displayed by default. To adjust the period displayed please use the "Period reported" or "Period concerned" filter.
