Our proposals

To connect new energy parks in Powys, we are proposing a new 132 kV connection.

• A new 132 kV Cors y Garreg collector substation near Cefn Coch, Powys, together with approximately 2.5km of underground cable from the Llyn Lort Energy Park Substation to the Cors y Garreg Collector Substation.
• Approximately 50km double circuit 132 kV overhead line, supported on steel lattice pylons from the Cors y Garreg Collector Substation to a new switching station near Lower Frankton.
• A new switching station near Lower Frankton which will connect the overhead line to the existing National Grid Transmission 400 kV national electricity transmission system in Shropshire, England.

Land will be required for environmental mitigation, compensation, and enhancement. As well as the permanent infrastructure, land would also be required temporarily for construction activities including, for example, working areas for construction equipment and machinery, site offices, welfare, storage and construction access.

To facilitate our connection request, National Grid Electricity Transmission will be developing its own proposals for a 400 kV substation in the Lower Frankton area, which will connect to our proposed 132 kV switching station.
