G83 Microgeneration limits

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.

To fall under the G83 connection process the microgeneration must be installed in an approved manner, must be below a certain size and must use G83 certified equipment.

From 1 March 2014 the limits for microgeneration must now comply with the new Electricity Safety, Quality and Continuity Regulations (Northern Ireland) 2012, helping to reduce potential impacts on the network and aligning NIE Networks' G83 limits with those that apply across the UK.

The G83 limits are:
  • 3.68kW for single phase installations
  • 11.04kW for three phase installations.
