It is your responsibility to ensure that you are fully compliant with all the necessary requirements for your type classification. All the requirements for each type are outlined in these documents from the Energy Networks Association. For your connection, you will need to provide a Power Generating Module Document (PGMD) which summarises how your generation is compliant. The document will need to be completed and updated through all stages of the project to ensure all data has been submitted to us, the DNO. This document lists all compliance requirements and the acceptable forms of evidence, specifically:
- S -Simulation study
- P -Design data
- MI -Manufacturers’ Information
- D -Copies of correspondence or other documents
- T -results of, and/or witness, tests or monitoring
- TV -Indicates type test reportsIt also contains a compliance declaration, which you the generator must sign.

Compliance with the latest Harmonic Standard
Harmonic distortion limits and compliance requirements have changed with the implementation on 17th June 2020 of Engineering Recommendation G5 Issue 5 2020 entitled “Harmonic voltage distortion and the connection of harmonic sources and/or resonant plant to transmission systems and distribution networks in the United Kingdom”. Further information on how this affects your connection can be sought from firstname.lastname@example.org.
I have a query regarding an existing or future connection and G99 compliance
If your scheme is already in construction and you have an allocated project manager, you can contact them with any queries regarding G99 compliance. Additionally you can also email email@example.com with any questions.
