Microgeneration (G83) application process

Microgeneration renewable technologies including solar panels and hydro or wind turbines can be used to generate electricity, reduce consumption and export some of that electricity to the grid. These microgeneration installations are typically connected to homes, farms and small commercial premises and are installed under a simplified connection process known as G83.

Micro scale - Stage 1 (single installation)   
Micro scale - Stage 2 (multiple installations)   

All customers must notify NIE Networks that a G83 connection has been made. This should be done at or before the time of commissioning every generator.

Please note: Installers must also submit the relevant G83 documentation for each generator within 30 days for approval to allow installation of the import/export meter by NIE Networks.

For multiple units you need to get prior written agreement from NIE Networks before you can connect.

Typical G83 schemes

  • Single phase solar, hydro or wind technologies which generate up to a maximum of 3.68 kilowatts of electricity. These will typically be connected to domestic premises. An existing single phase connection must already be available.
  • Three phase solar, hydro or wind technologies which generate up to a maximum of 11.04 kilowatts of electricity. These will typically be connected to a farm or small commercial premises. An existing electricity connection must already be available.
Please note: If your renewable generator is producing more than 11.04 kilowatts of electricity, you should visit our section on small scale generation connections.

At Northern Ireland Electricity Networks (NIE Networks), we are responsible for recording your G83 microgeneration scheme and changing your electricity meter to facilitate the export of units generated.

You need to agree a purchase contract with an export supplier to sell your electricity units [NB. You may have two electricity suppliers – you may buy electricity from one supplier and sell or export electricity to another supplier].

NIE Networks has no involvement in the purchase contract agreement – your chosen export electricity supplier will provide this information. It is your responsibility to provide export meter readings to your export supplier.
