G59 Generator Interface Protection
Generators that connect to the electricity grid should be compliant with the Distribution Code
. This code is regularly consulted upon with a wide range of stakeholders and has recently been updated with new Generator Interface Protection settings for Small Scale Generators.
Generators are required to update the interface protection settings on your generator by 30th September 2019 and confirm this has been completed.
This technical update is designed to:
- Reduce nuisance tripping and ad hoc disconnection of small scale generators
- Enable the 2020 Government targets for renewable energy to be met
- Bring small scale generators in line with large scale generators who implemented the settings change last year
G59 Protection Update Guidance Document provides the full technical details of the required changes and the reasons why they are being implemented.

- Confirm to NIE Networks that you have received the G59 notification and that you have engaged a G59 contractor:
- Engage a qualified engineer to update the protection settings at your generator.
- For generators with a high voltage connection, book an appointment for an NIE Networks’ engineer to witness a protection test of the new settings.
In some circumstances the application of the new protection settings may require new equipment which could delay the completion of the changes; your G59 contractor can provide further guidance on this matter.
NIE Networks will refer any generator which fails to make the protection changes by the required date to the Utility Regulator for further action.
