LCNF project funding The original project cost was £450,000, whereas, the actual project cost £620,000 (+37%).
Project objectives The key objectives of this project were to:
• Release network capacity for 132kV wind generation;
• Provide SP Energy Network’s control room with complete thermal visibility of the North Wales 132kV overhead line
network from Connah’s Quay to Pentir;
• Gain business confidence to move forwards to offering active network management (ANM) solutions for prospective
generation customers.

Overview of assessment, sources of evidence and comments
The project clearly facilitates the connection of low carbon generation or demand, the carbon benefits not
specifically quantified
Evidence:
The project proves that RTTR can be used to support ANM – which in turn would allow greater renewable
energy capacity to be connected, and/or to increase the generation output from capacity already
connected.
The evidence for this potential is strong within the close out report.
However the scope of the project does not take the additional step of using RTTR with ANM and hence
increasing low carbon generation connection.
The amount of additional wind generation is quantified, but the amount of carbon saved is not calculated.
