The Grid

We have an ongoing need to develop the electricity transmission grid. This ensures a secure and reliable supply of electricity now, for the future, and for our children’s future. On this page, you can find out about current and recent projects for grid development, wayleave agreements and open consultations.

We only plan new transmission infrastructure to keep the grid secure, and to prepare for future needs. On this page, you can find out about current and recent projects for grid development in your area.

Have Your Say on Grid Development

At SONI, we have two core responsibilities. We manage the flow of power across the grid to meet daily needs, and we also plan for the future of the grid. This involves the improvement and technological upgrade of our network.

Improving and upgrading the grid is a significant task that often requires major infrastructure. We want your input when making decisions about grid development. Read more about how to 'Have Your Say' here.



A wayleave agreement is a contractual licence which allows NIE Networks to access, construct and maintain electricity infrastructure upon the owners’ lands in exchange for an agreed annual wayleave payment made by NIE Networks.

SONI is responsible for obtaining the consents from landowners required to permit NIE Networks to install and retain new transmission infrastructure over and across the owners' lands. When planning authorities approve the development of new transmission infrastructure, SONI will seek to secure a wayleave agreement from each landowner before NIE Networks starts construction of the new infrastructure.

These wayleave agreements are voluntary. They permit NIE Networks to enter the lands specified in the agreement, and to carry out certain tasks.

If you have a query in relation to an existing wayleave or a new distribution system project then please contact NIE Networks - contact details below.

Phone: NIE Networks customer helpline 03457 643 643 is open 8.30am - 5pm Monday to Friday.
