About embedded generators
Embedded generators (EmGs) are connected to your electricity supply and provide electricity for onsite use. They also have the capability to export electricity back to the grid.
JE provides the remainder of the electricity demand to the site, including a backup service when an EmG is not operational.
Types of generator
Typical examples of EmGs that may qualify for our Buy Back Commercial tariff include:
- Wind turbines
- Photovoltaic (solar panels)
- Combined heat and power systems (CHP)
Embedded generators must be:
- Up to a facility size of 50kWp 3 Phase / 20kWp Single Phase
- Approved by Jersey Electricity under Engineering Recommendations G83/2 or G59/3, depending on the rating of the generator
- Connected in parallel to our network
Installations above 50kWp will be reviewed on a case-by-case basis. Typical kW peak refers to the maximum rating of the EmG.
