Compliance and testing for generators
Units connected to the grid must follow rules in the Grid Code. See how the testing and compliance process works.
Compliance and testing procedure
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.
Requirements for generators (RfG)
The European Network's Requirements for Generators (RfG) sets standards for connecting to the grid. Under this, we have updated the SONI Grid Code.
This means that generators need to be defined as RfG or non-RfG. See below for a definition of each. Grid Code clauses which are not defined as either non-RfG or RfG are applicable to all users.
Testing for conventional generators
Generators must demonstrate Grid Code compliance. We recommended you contact us at an early stage of your project to understand compliance testing requirements.
The Progress Summary lists all tests that conventional generators must complete to achieve an Operational Certificate.
These tests are divided into:
- Phase A - up to energisation
- Phase B - up to synchronisation
- Phase C - up to operational certificate
Find template procedures for each operational test below.
