High voltage substations

We have for the last 10 years assisted in the design of high voltage sub stations.  Working with electrical contractors and designers, we have designed sub station buildings and external electrical compounds from 11kV to 600kV, designing one of the only self build 600kV substations in Scotland.  Working with EDF Energy Renewables and their contractors, we provided a range of support to a large project in the Scottish Borders which was constructed over a 2 year period.

For more information on the project, please see EDF Energy Renewables project page.
