About the project
Scottish and Southern Electricity Networks (SSEN), operating as Scottish Hydro Electric Transmission plc (SHET) under licence has plans to construct a new 400/275kV substation adjacent an existing transmission line, west of the Wood of Middleton approximately two miles west of village of Rothienorman. The substation was first granted planning permission in February 2012, however due to changing network requirements and to accommodate overhead line tie ins with the substation, there have been minor changes to the proposed site layout resulting in SSEN taking the decision to submit a new planning application taking account of these changes.
These works are required to allow increased generation capacity access to the transmission system, while keeping the network fully operable and compliant with all necessary technical standards. Without these necessary reinforcements, the network cannot facilitate all generation connections.
Establishing a substation at Rothienorman addresses this issue and in effect increases the networks efficiency and capability. Power sharing across these circuits becomes more important as generation load increases on the system.
