System Warnings are messages published by the System Operator to inform all involved parties of important information concerning operational and commercial issues. For example, System Warnings are used to notify a shortfall in electricity margins (Electricity Margin Notice), Demand Control Warnings, IT System Outages or Failures, Risk of System Disturbance and Manifest Error Claims.

The System Warnings facility is also utilised by the System Operator to publish details of agreed Pre-Gate BMU Transactions (PGBTs) and notification of amended Acceptance Data relating to Emergency Instructions.
