Overview
Status: Operational
About the Project
We have constructed a new 400/275kV substation adjacent to the existing transmission overhead line at New Deer, in the north east of Scotland.
The substation has been constructed to operate at a voltage of 275kV, with a view to being upgraded to operate at 400kV in the future. The transmission system in the north east and east coast of Scotland will be upgraded to 400kV over the next decade, in order to facilitate this, we are proposing both upgrading the existing overhead line network in the region and installing new substations at various points.
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 the substation at New Deer 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.
Why is the Project Required?
There is a significant amount of renewable energy scheduled to connect to the energy transmission network in the north east of Scotland over the next ten years. One of the key generators of this is the Moray Offshore East Wind Farm, a 900MW offshore wind farm situated in the Moray Firth, which was given consent by the Scottish Government in 2014.
It has been determined that New Deer is the optimum location for Moray Offshore East to connect to the GB transmission network. To facilitate this connection, there will be two substations built at New Deer. One of which will be owned by Moray Offshore East and the other will be owned, operated and maintained by us.

Community Engagement
Throughout the life of our projects, we aim to work positively with local communities and keep people informed about what we are doing. This is particularly important when we are developing a proposal and we want to understand what local people think about our plans.
We endeavour to take the time to discuss proposals with local community councils, encourage engagement from the wider community and listen to the feedback we receive.
We will do our best to answer any questions and address issues or concerns that are raised with us.
When our project progresses into construction, we will continue working closely with the local community to ensure that our work has as little impact on the lives of those living and working in the area and as many long term positive effects as possible.
How we’re embracing artificial intelligence (AI)
We intend to use AI to assist our experienced teams in the analysis of your feedback, so we can categorise key points raised more quickly. You can learn more about how we’re utilising AI on this dedicated web page.

Energisation of New Deer Substation
SSEN Transmission announced today yet another important milestone on the pathway to net zero, energising the first g3 gas-insulated substation on its network at New Deer, leading the UK’s electricity industry with the world’s largest installation to date of GE’s g3 SF6-free gas. The new substation will not only facilitate the connection of 900MW new clean renewable energy to the grid from Moray East Offshore Windfarm, but by installing GE’s g3 gas, it is helping to support the transition to net zero emissions and the fight against climate change by reducing SF₆ gas usage on the transmission network.The energisation of the site marks just over two years of hard work for SSEN Transmission and their principal contractors, a consortium of GE and Amey, to bring the substation online. Now energised, the substation forms part of SSEN Transmission’s reinforcement and improvement of the transmission network in the North East and East Coast of Scotland enabling renewable generation to be transported from where it is generated to centres of demand across the country. -
New Deer Primary School
Scottish & Southern Electricity Networks (SSEN) Transmission and Amey staff visited the New Deer Primary School this week to talk to the children about keeping road safe and to put their skills to good use, tidying up the school’s eco-garden, repairing and painting some planters and donating some park benches for the children.
