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.
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.
