Grid Code Compliance & Testing

Units controlled by EirGrid must comply with technical rules in the Grid Code. See how the testing and compliance process works.

Grid Code Compliance & Testing

Units must test their performance when they connect to the grid for the first time, make changes, or return from maintenance.

We witness these tests and you compare the results to the Grid Code rules. If a unit passes the tests, we issue an Operational Notification allowing them to operate. If a unit can’t comply with a rule they may apply for derogation from the Grid Code.
