Our online applications service is currently a beta version. We would welcome any feedback on how we can improve this service for customers.
The G83 Stage 1 process is for single installations within a close geographical area. The Installer shall fit the microgeneration at the customer's site and commission the installation.
The Installer shall register the connection as soon as the site is commissioned. This allows us to initially register the site.
The Installer has 30 days from the date the site is commissioned to submit the completed commissioning documentation to NIE Networks.
This information verifies that each microgenerator installation complies with Engineering Recommendation G83/1 and is suitable to be connected to the electricity grid.
NIE Networks shall arrange to have an import/export meter fitted at the site (if required). An import/export meter records the electricity units being exported to the grid. This process can take up to four weeks.
You will need to agree a purchase contract with an export supplier to sell the electricity units being exported to the grid. Please note: you may have two electricity suppliers – you may buy electricity from one supplier and sell or export electricity to another supplier.
NIE Networks has no involvement in the purchase contract agreement – your chosen export electricity supplier will provide this information. It will be your responsibility to provide export meter readings to your export supplier.
For more information on electricity suppliers operating in Northern Ireland, you may wish to consult the Utility Regulator or the Consumer Council for Northern Ireland [links open in a new window].
The purchase agreement with your chosen electricity supplier will only come into effect after the import/export meter has been installed.
The Installer must submit an application for all proposed microgeneration connections at sites in a close geographic region (sites where more than one SSEG installation planned by the same organisation are within 500m of each other). The Installer should submit an application to NIE Networks as soon as possible to allow a network assessment to be conducted. The Installer may not fit or commission any generation at any site at this stage.
A Network Connection Study must be carried out for all G83 Stage 2 installations to assess the potential impact of the connection on the network. Once this assessment is complete NIE Networks will advise the installer of the outcome, which will be one of three options:
If reinforcement works are required, the Installer must either formally request a quotation from NIE Networks for the works or withdraw the application if they do not wish to proceed. A formal quotation shall be prepared and sent to the Installer within 90 days of NIE Networks receiving a formal request for a quote. This quotation is valid for 90 days after which the quote will expire and if a new quotation is required the costs may increase
Once the Installer has accepted the formal quotation and paid a 20% deposit; NIE Networks will proceed with the activities required to connect the generator to the distribution system. This may include obtaining legal consents, procuring equipment and the completion of any construction work. NIE Networks must be in receipt of full payment before any construction work begins.
Once any network reinforcement work (if required) is completed the Installer shall fit the microgeneration at the customer's site and commission the installation.
There is no additional documentation required.
You must provide the Meter Point Reference Number (MPRN) for the site where the microgeneration is to be installed in your application and your Meter Serial Number (if known). These are asked for on all of our G83 forms.
- MPRN (this is an 11 digit number that begins with 8 and can be found on your electricity bill)
- Meter serial number (this can be found on the front panel of the meter e.g. YH01234)
A small scale embedded generation (SSEG) Type Test Certificate is a guarantee from the generator manufacturer that their generator complies with G83/1 legislation. This can be obtained from your generator manufacturer.
The type verification test certificate for your SSEG must include the following information:
An electrical schematic shows the circuit diagram of the installation. This will include details of the inverter.
G83 Stage 1 is a fit and inform process i.e. the Installer shall fit the microgeneration at a single site and then inform NIE Networks once the site is commissioned. The registration form allows the Installer to inform NIE Networks that a site has been commissioned so that we may initially register the site.
The Installer has 30 days from the date of commissioning to submit the commissioning documentation for a site. NIE Networks shall check the commissioning documents for compliance and then arrange to fit an import/export meter at the site.
You can submit this online or alternatively download a G83 Stage 1 Commissioning Pack and submit by post.
When installing microgeneration at multiple sites in a close geographic region, the Installer must inform NIE Networks of their intentions to connect at the earliest opportunity by submitting an application form. The application form asks for details specific to each site.
NIE Networks will undertake a network assessment of the connection once an application form is submitted to determine its potential effects on the network and whether reinforcement work is needed before the connection can proceed.
You can submit this online or alternatively download a G83 Stage 2 Application Form and submit by post.
Once the Installer has been given permission to connect to the network the Installer shall fit the microgeneration at the site and then inform NIE Networks once the site is commissioned. The Installer will register each connection with NIE Networks once each site is commissioned by completing a registration form.
A seperate registration form must be completed for each site.
The Installer has 30 days from the date of commissioning to submit the commissioning documentation for each individual site. An individual submission must be made for each site and submitted to NIE Networks within 30 days from the site was commissioned. NIE Networks shall check the commissioning documents for compliance then arrange to fit an import/export meter at the site.
You can submit this online or alternatively download a G83 Stage 2 Commissioning Pack and submit by post.
