Integrated Micro Generation and Storage Procedure (G99/NI Fast Track)

Apply online here
You should consult with a micro generation installer before submitting an application form.

Once you submit your application online you will receive confirmation via email. Once we review your application you will get your job reference number and a request for the application fee of £250 within 5 working days. Please quote this reference number when contacting us about your application.

Once the fee is received, your application will be passed to our Generation Planning Team to carry out Network Design and Analysis in order to assess if the network is capable of accommodating the connection of your power generating modules or if network upgrade works are required. Please note - If there are multiple applications for micro generation installations planned by the same organisation within a distance of 500m of each other and installed within 28 days of each other, this will require more detailed studies than micro-generation installations at a single domestic site.

If the Design Analysis determines that network reinforcements are necessary, we will provide an estimate of costs to the installer who must confirm within 30 days if they wish to proceed with the connection. If so, we will issue a formal quote, terms and conditions and a connection agreement for the works required. The offer is valid for 90 days and the payment along with signed copies of the Acceptance of Terms and Connection Agreement documents must be submitted within this period before NIE Networks can begin upgrading the network. The power generating modules must not be connected until all reinforcement work is complete and an Authorisation Letter has been provided by us.

Following the design analysis and once any necessary reinforcement works are completed, NIE Networks will issue an Authorisation letter to the installer. This letter will also contain a Connection Agreement, as well as the required commissioning forms for the installation.

Within 90 days of the date of the authorisation letter, the installation must be commissioned and your installer must complete the Commissioning forms for the installation. Please note that individual commissioning forms must be completed for each of the new power generating modules within the building, as well for the Export Limiting Scheme.  They must then sign the Connection Agreement and return this to us

If wiring changes that affect your meter have been carried out during commissioning, you must download a connection card and get your electrician/electrical consultant to fill in the details. Submit this online to ConnectionCard@nienetworks.co.uk.

If you are installing a new micro generator along with a storage device, we will contact you to arrange an appointment to configure your meter for export.

NIE Networks will counter-sign the connection agreement and send a copy of this back to the installer.

You will need to pay the appropriate fee before your application will be considered valid. Please see current fees in schedule 2 of our statement of charges and read our guide to application fees.

To complete your application you will need to provide information for the following sections:

1. Installer details
2. Site details including site contact details (please specify, if this is different)
3. Payment details (contact details of the person paying for the connection)

A Meter Point Registration Number (MPRN) is a unique 11 digit reference used in Northern Ireland to identify electricity supply points. It can be found on the back of your electricity meter or on your electricity bill. Your meter serial number can be found on the front panel of your meter.

A circuit diagram of the proposed connection clearly identifying how the connection shall implement an export limited to 16 Amps per phase. Your Installer should provide you with this:

For customers wishing to apply for a connection of a micro storage device (such as a battery) above 16 Amps per phase and less than 32 Amps per phase

Once authorisation to connect has been given, the system must be
installed and commissioned within 90 days from the date of
authorisation letter.
A Connection Agreement and Commissioning forms must be completed for the site and
submitted to NIE Networks .
NIE Networks shall check the commissioning documents for compliance
then arrange to fit an import/export meter at the site if necessary.
