At SONI, we operate the transmission system, or the electricity grid as it’s better known, every minute of every day to ensure electricity can flow from where it is generated to where it is needed at the lowest price possible for the Northern Ireland consumer.
SONI also has the crucial responsibility of planning and delivering a transformation of the power system to enable a cleaner energy future. This includes interconnection to neighbouring grids and running the wholesale electricity market.
The transmission grid and its infrastructure need to be made stronger and more flexible to transport the increases in clean energy generation which we expect to see over the next number of years. It also needs to be secure so that consumers have the high quality and reliable electricity supply they have come to expect.
This infrastructure upgrade is the most significant in its scale and impact since rural electrification and it is a mission-critical step on the journey to net-zero carbon emissions by 2050.
To more effectively manage and process this work, SONI and NIE Networks established a dedicated Joint Programme Management Office (JPMO) to oversee, co-ordinate and where possible accelerate this transmission investment programme. The focus of JPMO is on integrated planning, deeper collaboration, accountability and more regular reporting, to provide more robust timelines for individual project delivery and the overall development plan.
The projects outlined in our Draft Transmission Development Plan will ensure the transmission grid is fit for the future, providing for Northern Ireland’s environmental, societal and economic aspirations. They are critical enabling infrastructure in the realisation of the Northern Ireland Energy Strategy and Climate Change Act (2022).
Given the importance of this Plan in meeting Northern Ireland’s energy and climate change ambitions, the views and feedback from the energy industry, government, and other key stakeholders on its details are of vital importance.
We would like to thank all stakeholders and interested parties who respond to the Draft Transmission Development Plan Consultation. Your feedback is important to us.
We look forward to your consultation responses on the proposals contained in this document and welcome feedback via our Consultation Portal or by email (info@soni.ltd.uk) until 5pm on the 17th January 2026.
