Errors and warnings

Background​

The Engine generates error and warning messages based on input data, results from power system software or through unexpected behaviour. Below is a list of Engine errors and warnings which have additional information on what is causing the error or warning and how to resolve it.

As always, if you need help with an error or warning, please reach out to gridmo support.
