Renewable generators urged to check loss of mains settings

10 February 2021

New requirements have been introduced for grid-connected generation equipment such as non-domestic solar and wind power from small-scale to 50 MW systems.

This has been introduced as a result of Distribution Code updates (Engineering Recommendation G59 has been upgraded). Loss of Mains (LoM) protection settings need to be changed to remain compliant – in many cases, this is just a matter of adjusting settings on existing equipment.

The new settings will allow generators to “ride through” or continue operating without disconnecting when minor faults occur on the system, allowing for a continuous supply.

If new relay equipment and setting changes are needed for equipment installed before February 2018, grant funding is available through a quarterly application process under the Accelerated Loss of Mains Change Programme administered by the Energy Networks Association. We understand that most sites successful in obtaining funding will have the costs covered in full.

The current deadline for final applications is 10 May 2022, but it is worth bearing in mind that the final application deadline could be brought forward at any time.

NFU Energy can offer further advice on the G59 upgrade and help with obtaining funding – call them now on 024 7669 6512 or aW5mb0BuZnVlbmVyZ3kuY28udWs=
