Works to existing infrastructure (Sections A, C and E)

We need to install additional equipment at the 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). We would also need to build and dismantle an existing gantry, build a new gantry and section of cable at this substation. All construction works, including the construction of any temporary compounds, would take place within the existing operational land at Osbaldwick substation.

We need to carry out upgrading works to the existing 275kV Poppleton to Monk Fryston XC/XCP overhead line route to accommodate the new sections of overhead lines, as set out in the previous sections. Works along this route would involve replacing the conductors (overhead wires) and fittings. Here we are increasing the number of conductors from single to twin, doubling the number of wires on each arm of the pylon to allow the overhead line to transport more power.
