Grid Development Process

We need to plan the development of the transmission system to ensure a safe, secure, economic and reliable electricity network. This includes allowing for growth in demand and connecting new generation sources including renewables.

From time to time we need to develop individual projects which we do in co-operation with NIE Networks. This brochure sets out how we make decisions on these investment projects and how you can input into them. Our three-part process puts stakeholder and public consultation at the heart of how we develop the transmission grid. Read more about this three-part process here.
