Overview
About the Project
We are constructing a new 400kV substation adjacent to the existing 275kV substation at Peterhead. We previously consulted on proposals for a new substation at Peterhead in 2013, however due to the changing requirements in the transmission network, we have undertaken further system and technical analysis to ensure that our proposals meet the future requirements of the network.
Due to network analysis and a significant increase in onshore and offshore generation within the north east of Scotland, there is a requirement for us to reinforce the transmission network at Peterhead through the provision of a 400kV substation. The new substation will comprise of four enclosed super grid transformers, a 400kV gas-insulated busbar, substation control building and associated infrastructure.
Our proposals will also provide consideration of our plans to reinforce the existing 275kV overhead line, which connects the substations at Blackhillock, Keith, Kintore and Peterhead, to enable operation at an increased voltage of 400kV.

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.
