Outcomes

The work conducted by IBM produced two designs – one based on using a public communications network and one based on using a private communications network.

IBM noted that a combined solution is required that utilises different communication methods and different edge computing requirements dependent on the GSM signal strength within the substation. They also recommended using a cloud hosted IoT platform to manage the connected devices. The Cloud provider and IoT platform provider can be from different suppliers.

MQTT was recommended as the protocol to be used to collect the data due to its integration with the IoT platform and IBM suggested that Electricity North West convert MQTT into our standard protocol, DNP3, within the DMZ.  For control elements DNP3 sent directly from the SCADA system should continue to be used. 

Following this work with IBM, Electricity North West to procured equipment to install in our test area to test the end to end functionality including the access to data by control systems, planning staff and third parties.

The project explored the need for “Big Data” and highlighted how it could be shared but due to recent and enhanced cyber-attack to critical national infrastructure the decision to progress the original project intention was scaled back. We are now exploring alternative methods of data management and transmission into our NMS SCADA system.

Interface highlighted the risks associated with Critical National Infrastructure, and the possible cyber threats expanding the IoT to these systems.

Lessons Learnt

Cyber security requirements are constantly changing and can affect the delivery and implementation of new technologies and processes. It is important that Innovation teams involve the cyber teams throughout the project so that issues can be raised and addressed in a timely manner.
