Eastern Green Link 2
A 2GW high voltage direct current (HVDC) electrical ‘superhighway’ cable link beginning construction between Peterhead in Aberdeenshire, Scotland and Drax in North Yorkshire, England.
Carlisle to Newcastle
A proposal in its early stages of development to upgrade the electricity network between the North West and North East of England.
Carlisle to NewcastleHow we’re working with local communities
We’re committed to engaging communities as we develop our proposals and do this in a number of ways:
We work with local communities and stakeholders to understand what’s important to them and endeavour to deliver initiatives that support those priorities – from developing skills opportunities to supporting local community projects through our Community Grant Programme.
We work with relevant authorities as we develop our engagement plans, to ensure they’re tailored to, and meet the needs of, the local communities.
We conduct ongoing engagement and undertake consultation exercises. For this we use different methods of communication to ensure we’re hearing a wide range of views across these communities, which hugely supports with the development of our projects.
Do you have a question about local communities?
The Great Grid Upgrade is the largest overhaul of the electricity grid in generations, connecting more clean, secure energy to power the things we love.
