Installing Distributed Generation rated at 3.68kW or higher

If you're looking to install large scale Distributed Generation (DG) equipment rated at 3.68kW or higher, you will need to apply in advance to receive a quote from us to connect to our electricity network. We'll assess your application to understand the work involved before sending you a quotation. On the day of the installation we may need to be there to complete some tests to make sure there are no issues.

Before you apply

• To get an idea of the capacity of our electricity network in your local area, you can check our DG heat map tool.
• If you would like to discuss your project with us before making an application, you can book a one to one surgery session with one of our experts for help and advice. 

The application form which you need to complete will depend on the size the  generation equipment you want to install.

• To connect generation equipment rated at 3.68kW up to 50kW you will need to complete the G99 - A1.1 Application Form. 
• For all generation equipment rated at 50kW or higher, you will need to complete both the (ENA) G99 Generator Standard Application Form and also the relevant supplementary form on the ENA website. 
• The supplementary form you need to complete will depend on the generation equipment you are installing. For more information please download the  Engineering Recommendation (EREC) G99 below. 
• Once you have completed the required form you will need to send it back to us at connections.gateway@ukpowernetworks.co.uk
