Connecting to the National Grid

Once you have decided on the best technology for your location, you will need to consider grid connection. Renewable energy generators which produce electricity will normally be grid connected. Battery storage of electricity is an option on off-grid pylonsites.

All generators must have an agreement from your Utility Company to connect to the electricity grid. Even if it appears that the renewable electricity generator is connected into your house/building ring main, it is still “grid connected” as long as your property is grid connected. Renewable energy generators under 5kW will need a connection agreement called G83. Larger generators will need a connection agreement called G59.

Prospective renewable energy generators can usually register their application for grid connection online (see below).
Once you or TAEC have forwarded your G83 or G59 application to your Utility Company, it will be assessed and the Utility Company will contact you regarding any upgrade of transformers or other costs involved. Your Utility Company will then ask you to sign a “Generator Agreement”. TAEC or their installer will also be required to complete a “Commissioning Form” to ensure that the renewable electricity generator has been installed safely. These should then be returned to your Utility Company, who will in turn sign the appropriate agreements, and return then to you for safekeeping.

This is an example of the NEI process:

Electricity Suppliers - How do I find out who my supplier is?

Each property has an MPAN for electricity or an MPR for gas. These numbers are controlled and issued by either your local electricity supplier (known as a Host REC) or the gas transporter to the property. Please contact them directly, giving them either your MPAN or MPR number to find out exactly who your supplier is.

How do I get my MPAN?

You should be able to locate your MPAN on your electricity bill.  If you have any difficulty, contact the local electricity supplier.  If you ask for their MPAS department, they should be able to either tell you the full 21 digit MPAN or arrange to send it to you.
