The Project

SONI is the electricity transmission system operator for Northern Ireland.  This means we plan for the future of the electricity grid and operate it every minute of every day. We ensure that everyone has power when they need it at the most economical price possible.

To prepare for a clean energy future, SONI must make the electricity grid stronger and more flexible. The grid will need to carry more power, and most of this power will come from renewable generation that varies depending on the weather.


What will the project involve?

The existing three main circuits between Omagh and Tamnamore are heavily congested. With further increases in renewable energy by 2030 all existing circuits on the Omagh to Tamnamore corridor are at significant risk of overloading.

SONI’s preliminary preferred option will construct a new 110 kV circuit between Omagh and Tamnamore.

What are the benefits of this project?

  • Removes constraints on the grid in the west of Northern Ireland;
  • Addresses future security of supply;
  • Improves capacity and efficiency of the grid;
  • Vital to deliver our climate target of 80% renewable generation by 2030.
