What are we proposing in the Monk Fryston substation area? (Section F)

To manage the power flows on the existing 275kV Poppleton to Monk Fryston (XC/XCP) overhead line, we need to create a second substation at Monk Fryston.

This new substation area is presented as ‘Section F’ within our Consultation Plans. The plans consist of proposed new infrastructure and changes to existing infrastructure.

What permanent infrastructure is being proposed in this area?

400/275kV Monk Fryston substation (new)

To increase and strengthen network capacity to accommodate the increasing energy flows we would need to build a new 400/275kV substation. This new substation would be located adjacent to (and connecting into) the existing Monk Fryston substation, which otherwise would be unable to accommodate the additional energy flowing from the uprated overhead lines.

The substation would:

  • have a footprint of approximately 80,000m2 (8 hectares);

  • have a maximum height of 15m at its highest point (including the gantries), although the heights of the substation and equipment are yet to be finalised;

  • contain four Super Grid Transformers (SGT) to help convert the voltage of the overhead lines (275kV)

  • to connect into the substation (400kV); and

  • include approximately 600m of underground cables to connect the overhead line circuits to the new substation.

What changes are we proposing to existing infrastructure in this area?

Proposed changes to existing infrastructure in the Monk Fryston Substation Area

To help manage the power flows into the new substation at Monk Fryston, we are proposing the following changes to existing infrastructure in this area:

  • reconfiguring the existing 275kV Poppleton to Monk Fryston (XC) overhead line to connect into the new substation, including the installation of new spans of overhead line where needed;

  • removing and installing new pylons, resulting in one additional pylon in this area, along with two new gantries to allow the overhead line to connect to the new substation; and

  • reconfiguring a short section of the existing 400kV Eggborough to Monk Fryston overhead line to connect into the new substation, along with dismantling approximately 350m of existing overhead line.

Your Feedback

We are seeking your views on the proposed location of the new Monk Fryston substation. We would welcome comments on any specific locations (including access arrangements, mitigation) or issues that we should consider when refining our plans in this area:
