How to install

To install large scale Distributed Generation (DG) equipment rated at 3.68kW or higher, you will need to apply in advance. 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.

Before you apply

  • Check our DG heat map tool to get an idea of the capacity of our electricity network in your local area.
  • You can book a one-to-one surgery to discuss your project with one of our experts.

Steps to follow

Step 1
Complete the relevant application form below or apply using Smart Connect if eligible.  
Step 2
We assess your application form. 
Step 3
We provide you with a quote to connect based on the work involved.
Step 4
Your installer can connect your generation to our network. We may need to be there on the day.

Which application to complete

Some installations can use Smart Connect, a tool which allows installers to apply for single domestic installations. Smart Connect will automatically assess applications and either issue approval or refer the application to the relevant team. Check if your installation is eligible to be raised on Smart Connect.

If your installation does not meet Smart Connect criteria follow the steps below:

  • To connect generation equipment rated at 3.68kW up to 50kW, complete the G99 - A1.1 Application Form. 
  • For all generation equipment rated at 50kW or higher, 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. To check which one, download the  Engineering Recommendation (EREC) G99 below. 
  • Once you have completed the required forms, send it back to us at connections.gateway@ukpowernetworks.co.uk
