Preparing the electricity network for the transition to net zero and maintaining an efficient and secure power supply in England and Wales.
Discover some of the work our teams deliver and find out more about how we work in the articles below.
How we locate new substations
As the volume of connections increases, new substations must be triggered to accommodate additional capacity across our network. But how do we determine their location?
How we procure and deliver infrastructure
National Grid is committed to building a resilient, future-ready electricity transmission network that supports the UK’s clean energy goals. Through a robust procurement strategy and building strategic partnerships, we're committed to safely, reliably and efficiently connecting our customers to the network.
User connection configurations
Connections consider a variety of factors, including multiple connections, system requirements and DNO (Distribution Network Operators) demands. But what are the types of user connections used on the transmission network?
User connection configurationsEnabling works
When more connections wish to export or import extra energy to or from the grid certain works can be needed to accommodate the extra capacity. But what do these works include?
Enabling worksUser connection boundaries
When considering connections, its crucially important to be clear on the boundaries of responsibility between National Grid Electricity Transmission, and the user which is connecting. But where are these boundaries?
