Additional works

We need to do some additional work as part of the Yorkshire GREEN project proposals to ensure that the network can manage the additional energy flows, including: 

• Additional equipment at Osbaldwick substation, including an isolator (a safety device which disconnects a circuit from electrical supply) and a circuit breaker (a switch which manages and protects power flow). 

• Replacing the conductors (overhead wires) and fittings on the existing 275kV Poppleton to Monk Fryston (XC/XCP) overhead line. We will need two sets of wires on each side of the pylons; at the moment there is only a single set on each side. We may also need to strengthen or replace some existing pylons to carry the additional weight of the extra wires. 

• Updating substation protection and control equipment and making changes at other remote substations, within the existing substation boundaries.
