Accelerated Loss Of Mains Change Programme

What Is The Accelerated Loss Of Mains Change Programme?

If you are an Renewable Energy Installer or Renewable Energy Plant owner then please take a few moments to read this....

The Accelerated Loss Of Mains Change Programme is taking place across Great Britain (excluding Northern Ireland) which is being run by both the National Grid and the DNO's. It is due to commence in August 2019 for a limited time.

 The reason for this is to update the LOM (Loss Of Mains) protection for existing Renewable Energy Generators. One of the main benefit of this is to reduce the amount of tripping by relaxing the RoCoF limits (rate of change of frequency).

 So, this programme is designed to get all existing sites updated and a Grant scheme is being rolled out on a first come first served basis.

 We can upgrade your Relay for free ensuring you stay compliant with the latest grid code. All you need to do is register your site with us ASAP.

 Get in touch and register with us today using the form at the bottom of this page.
