Planning your installation

This guide will help businesses that are considering installing all types of embedded generation. It covers the following topics:

Please carefully follow these steps to ensure your solar or wind installation meets our standards and guidelines.

Step 1 - Get planning permission & choose a certified installer

Before installing embedded generation, you must obtain the necessary planning permission from the Government of Jersey's Planning and Building Services.

When choosing your installer, ensure they have proper certification and are familiar with regulations G83 or G59 for fitting embedded generators.

Step 2 - Complete an Electricity Supply Enquiry (ESE)

To complete an Electricity Supply Enquiry (ESE) form you will need to provide the following:

  • A site location plan
  • A ground floor drawing with all existing services and/or the proposed new services marked
  • All your proposed electrical load in kilowatts (kW)
  • All your current electrical loads in kilowatts (kW)

The ESE should be completed by a person with a good knowledge of the property's required electrical loads. If you are not confident you can accurately work out the property's required electrical load, we recommend asking an experienced electrical contractor to complete the ESE on your behalf.

The ESE form is an editable PDF. You can complete it using a computer, or print it and fill it out by hand.

Step 4 - We confirm receipt of your application

Once we've received your completed ESE form, we will send you written confirmation and begin processing your application.

Step 5 - Submit an Embedded Generation form

At Jersey Electricity we refer to all solar, wind and CHP systems as embedded generation (EmG).

To ensure the installation of your system meets our guidelines, you'll need your installer to complete the correct Embedded Generation form. Please note that due to network restrictions, it may not be possible to connect larger loads.

Your installer can use our Embedded Generation Form Finder tool to find the correct form and guidelines. Alternatively, download our Embedded Generation form decision tree.

The correct Embedded Generation form must be completed BEFORE work on installing your system begins.

Step 6 - Installation inspection by our engineer

Once you have our approval and your installer has carried out your installation, we will send an engineer to inspect it.

Step 7 - Fitting a buy back meter

A Buy Back meter allows you to sell surplus electricity back to us at the Buy Back tariff rate.

Once your installation has been approved by our engineers, we can fit a Buy Back meter beside your existing meter at no cost.

If any changes need to be made to your existing meter, our engineers will advise you.

Standby charges for embedded generation

JE provides the remainder of the electricity demand to the site, including a backup service for when an EmG can't. A standby charge is applied for this. You can find details on charges associated with commercial embedded generators on the standby charge page.
