Small Scale Generation SCADA Implementation

There is a requirement within both the Distribution Code and individual Small Scale Generation Connection Agreements that all generators which are greater than 100kW, install and commission Supervisory Control and Data Acquisition (SCADA). Generators which are connected to NIE Networks' Distribution System should be compliant with the Distribution Code.

All owners of Small Scale Generation (SSG), with generators greater than 100kW are expected to comply with this mandatory requirement.

Implementation of SCADA will enable communication of real-time information and control between your generator and NIE Networks' Distribution Control Centre.

SCADA will:

  • Enable more accurate generation forecasting for the Wholesale Energy Market.
  • Provide high resolution data for planning electricity network development.
  • Enhance control of network voltage levels.
  • Bring Small Scale Generators in line with Large Scale Generators.

Full technical details of the changes you need to make to your generator and the reasons why they are being enforced are explained in the SSG SCADA Guidance Document.

In summary, by 31st August 2024 you will need to have:

  • Contracted with a Verified SCADA Installer to install and commission SCADA and Reactive Power Control at your generator.
  • Ensured that your Installer has confirmed a completion date for the SCADA and Reactive Power Control at your generator with NIE Networks.

Verified SCADA Installers SSG SCADA Acknowledgement Form


SSG sites that are repowering should contact NIE Networks directly at ssgscada@nienetworks.co.uk.

If you have previously informed NIE Networks of the SSG SCADA Installer you appointed and now wish to appoint a different installer, please make us aware of this change by completing the form below.

Update SCADA Installer


You should also be aware that on completion of your SCADA Installation, NIE Networks will perform Compliance Testing. This will confirm that your generator meets all requirements within the Distribution Code including Reactive Power control.

A timeline for the completion of SCADA and Reactive Power Control must be provided for all generators 100kW or above by 31st August 2024. Failure to make these mandatory changes by this date may result in your generator being disconnected from the Distribution Network.

Upon successful completion of a SAT where all SCADA Requirements are met (including Reactive Power control), a SAT Certificate will be issued to each generator. This will confirm that your generator has met the SCADA Requirements outlined in the Distribution Code. SCADA and Reactive Power control are ongoing requirements, so it is your responsibility to ensure that your SCADA installation continues to operate as required.

If you have any questions or require any further information, please contact the NIE Networks Generation Compliance Department at ssgscada@nienetworks.co.uk.
