For installations of above 3.68kW (kilowatts) per phase, but 50kW or less (If you have a three-phase supply, each phase must be 17kW or less.) For these larger projects, we will need to agree with you how best to connect your generator to our network. We may need to make some modifications to our network to allow your generator to operate correctly. Substantial work could be required therefore we recommend you contact your installer and liaise with us from an early stage especially before purchasing any equipment as the costs depend on a number of site specific variables. It can take up to 45 working days for you to receive a quotation from us for this application. The 45 working day countdown will start from the date you send us the correct information outlined below.
Your installer should provide the following information:
Completed ‘microgeneration connection (50kW or less)’ application form:
This should include the following:
- Property address
- Meter point administration number (MPAN)
- Proposed total capacity of generation installed (kW)
- Signed and dated Letter of authority from the landowner (Must be signed within the past 12 months)
Inverter Type Test Certificate
- The power rating (kW) on the certificate should match the power rating (kW) of the inverter shown on the schematic diagram
Schematic Drawing
- The generator itself
- Name and power rating (kW) of the inverter being used
- Live phases, neutral, earth
- Lockable isolators
- Clear demarcation between our and your equipment
Site plan

Once we have received all of the above information, we will register your project and your application will be passed to our connection designers to prepare your quotation.
