Ultimately, SSEN plan to upgrade around 1500 substations, but this will depend upon the success of these two initial test projects in two regions, Dundee and Thames Valley. ITI have signed an agreement to be the sole provider on a framework that will last five years. If these first two projects are a success and OFGEM approve the roll out, then ITI will manufacture and install the approved solution across the UK over the course of the next five years.
ITI are currently designing over 35 Operational Technology (OT) panels for the two sites, to provide industrial control systems combining protection, real time information systems and communication, which SSEN use to operate their primary assets. OT incorporates both automatic operation from protection systems or software signals, and manual action from an operator: everything from a button pressed on a keyboard in the control room, to the terminals of the operating coil on the switch on the LV, HV or EHV networks.
