Onshore substation location

During our statutory consultation, we presented four different converter station options across two different Substation Zones. The options were based on two different ways to transmit electrical power through cabling: high voltage alternating current (HVAC) and high voltage direct current (HVDC).

Following feedback from stakeholders and further engineering assessment, the decision has been made to remove HVAC from the design and to locate both HVDC converter stations in Substation Zone 4.

What will the substations look like?

Each substation will consist of several buildings housing electrical equipment and unhoused electrical equipment contained within secure fencing.

The substation equipment is expected to need around 20 hectares (50 acres) of land, in total, across both projects.

The final dimensions of the substations are dependent on the electrical capacity of the wind farms and the design of the electrical transmission used to transmit electricity to the substation.
