SONI Annual Performance Report 2022/23

21st December 2023

At SONI, we plan for the future of the electricity transmission grid and operate it every minute of every day. This includes interconnection to neighbouring grids and running the wholesale electricity market.

SONI has a pivotal role to play in the implementation of Northern Ireland’s new energy strategy, in particular, to achieving an average of at least 80% of our electricity from renewable sources by 2030, an important step on the journey to net-zero carbon emissions by 2050.

We have published our first Annual Performance Report for the period October 2022 to September 2023, which outlines how we have performed across our four SONI TSO roles. The Report considers our performance against the SONI Forward Work Plan 2022/23 which can be found here.
