This ESO-led commercial solution provides boundary benefit in the north of Wales

Replace the conductors on the remaining sections of the Coryton South to Tilbury circuit, which have not recently been reconductored with higher-rated conductors. These would increase the circuit’s thermal rating.

Install a power control device along the Cottam to West Burton 400 kV overhead line route. This would improve the capability to control the power flows from north to south of the transmission network.

This project is currently required to enable the development of a robust and reliable offshore network connection and will be reappraised in the detailed design

Replace the conductors on the Drax to Fenwick Tee 400kV circuit with higher-rated conductor to enable increased power flow.

Establish a new 400kV substation at Windyhill and a 400kV single circuit corridor, on existing overhead line routes, between Windyhill, Lambhill and Denny North substations.

Install a second 400/275kV transformer at Denny North 400kV Substation.

This reinforcement is to replace generator owned circuit breakers with higher-rated equivalents including substation equipment. This would allow higher fault levels, which in turn improves load sharing on circuits connecting to the substation.
