Our proposals

The new connection needs to have sufficient capacity to carry the energy from potential onshore wind developments in Mid Wales.

We've assessed options for how and where to connect the new energy parks to the existing electricity network, looking at options in Shropshire, North and South Wales.

A collector substation and a new 132 kV connection to the national transmission network in Shropshire is most efficient way to do this - it would provide capacity for Llyn Lort and other proposed windfarms in Mid Wales and avoid the need for a network of many, smaller individual connections.

We also assessed options for a route for the new connection. While developing the proposed route we considered the Holford Rules, which set out principles for routeing overhead lines, including choosing natural backgrounds rather than sky backgrounds, and using open valleys with wooded areas rather than areas at height.

We're proposing 27 metre steel lattice pylons. These are much shorter and less bulky than the pylons proposed previously in the area by National Grid - any visual effects are significantly less as a result.
