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.
