Building substations
Construction information
What’s involved in building a new high-voltage electricity connection?
Substations contain specialist equipment that changes electricity from very high voltages to lower voltages, so that it can then be distributed to businesses and homes. As part of the Hinkley Connection Project, we’re building two substations to support the network.
The ground at the site of a new substation will be levelled to provide a flat and stable surface before the foundations are excavated and concrete is poured in.
The substation structures will be assembled and fixed to the foundations.
Once the substation is complete and operational, surrounding land will be reinstated and planting undertaken to screen the site.
