A major extension at Coolkeeragh to ensure future security of electricity supply will get underway next year, the System Operator for Northern Ireland (SONI) has confirmed.
SONI, which runs the the NIE-owned transmission network, has listed a 110 kilovolt extension to the Derry power plant in its Forward Work Plan for 2023/24.
It says the project at Coolkeeragh, owned by ESB, will facilitate ‘renewable integration and security of supply’.
“This project will facilitate the future connection of a third interbus transformer, the restoration of the second busbar coupler and section switches and other improvements.
