Real DNO insight
Learn from practical experience, procedures, expectations, and challenges found inside the UK network-operator environment.
The high standard of engineers coming through our doors reflects the professionalism and ambition now driving the renewable and grid-connection sector — and we’re proud to support that journey.
During the training, learners worked with their own equipment — in this case, the advanced Megger Sverker 900, a major step forward from the old T&R DVS3 Mark 2. The course equips new trainees with essential knowledge of G99 connection requirements for Power Generating Facilities, covering synchronous generators, mains protection, and the impact of decentralised sources like wind, solar, and hydro on grid stability. Participants also gain hands-on experience with the latest G99/2 testing requirements, including updated ROCOF settings, ensuring they are fully prepared for safe and compliant grid integration.

The course had a good balance of practical and academic training. Lots of information imparted in a way that was easy to absorb.
Really interesting. Filled in some missing gapes and answered many questions.

Really Helpful, Great Information. All Great, Thanks.
For DNO engineers, employees, network operators, consultants, and professionals working closely with UK network operators.
Takes about two minutes. No complicated booking process.
Last month, we welcomed three DNO engineers from leading UK Distribution Network Operators. The two-day face-to-face training created an exceptional exchange of practical knowledge and real-world experience.
While they gained valuable insight from the course, we also learned more about the internal workings and day-to-day challenges of UK DNOs—knowledge that is difficult to find anywhere else.
We want to encourage this valuable interaction between DNO professionals, consultants, renewable-energy specialists, and solar installers. When these groups learn together and exchange views, everyone develops stronger knowledge and the whole industry benefits.
Learn from practical experience, procedures, expectations, and challenges found inside the UK network-operator environment.
Exchange knowledge with consultants, engineers, installers, and renewable-energy professionals in one learning environment.
Build clearer understanding, stronger working relationships, and better outcomes across the renewable-energy sector.

Everything is transparent. It was very good.
Very informative, Dave is a wealth of knowledge and breaks the course down to make training simple.
The training was very informative and paced to suit our level of knowledge and experience. I would highly recommend the training for anyone looking at G99 relay testing.
I thoroughly enjoyed it and the lunch were a good position and laid out very nicely. I like my food, thank you very much.
First to give a bit of context, I had limited knowledge regarding G99 requirements and I’ve never done any protection relay testing before. But thanks to Dave, I really understand the purpose of the test and how to perform it on the G99 relay. It is also nice to have access to the online courses to expand my understanding on the G99 grid connection process.
Thanks Dave. Excellent Course Material.

Great Job. And all because of the awesome guys from G99.training.
I really liked the training given on the testers.
The course is a lot more intensive than I had expected, but great information.
Loved this course.
