EVALUATION

AN INDEPENDENT EVALUATION OF THE LCNF
Interconnection of WPD and NGC SCADA
Project Title
Interconnection of WPD and NGC SCADA
Tier 1
DNO
WPD
Status
Complete
LCNF project funding £79,000
Project objectives This objective of this project was to establish a real time link between the SCADA systems operated by National Grid and
Western Power Distribution such that data on either system can be viewed on the other in real time. The objectives were to:
• Establish the link
• Establish access to the data and methods of viewing the data
• Establish the security measures required to ensure the security of the link to both of the systems against cyber-attack.

Overview of assessment, sources of evidence and comments
Assessment:
The project clearly facilitates the connection of low carbon generation or demand.
The carbon benefits not specifically quantified.
Evidence:
DNOs have real time visibility of EHV and significant HV connected distributed generation but NGC do
not. As the amount of DG increases it will become important for NGC to have real time visibility of their
operation to enable them to undertake system balancing and manage power flow.
With further research, an increased benefit to NGC could be delivered in terms of visibility of the end to
end electricity system and deliver reduced system risk to the UK as a whole. However, carbon benefits of
the project are not clearly defined or quantified.
