SSE Renewables Acquires 100 MW Battery Storage Project in Ireland

SSE Renewables has acquired a 100MW / 200MWh battery energy storage system near Dungannon, County Tyrone, Northern Ireland, from Heron Energy. Once approved, construction could commence early next year and will be operational by the end of 2026.  At an installed capacity of 100 MW/ 200 MWh, the Derrymeen battery energy storage system (BESS) would be the largest battery storage system in Northern Ireland. 

Subject to a final investment decision by SSE Renewables, the project will be constructed on a greenfield site located outside Coalisland, around five miles from Dungannon.

The Derrymeen BESS would be capable of storing up to 200 MWh of energy for flexible dispatch when needed for use by Northern Ireland homes and businesses at times of peak demand. When called upon, the system would be capable of providing back-up energy to the equivalent of over 135,000 homes in Northern Ireland for up to two hours at a time.

The Derrymeen project is SSE Renewables’ first battery storage development in Northern Ireland. It would deliver significant economic and job creation benefits to County Tyrone and Northern Ireland during construction. The project will play a pivotal role in the European battery storage market.

Daniel Barnes, Head of Solar and Battery Development (Ireland), SSE Renewables, said, “This acquisition further demonstrates SSE Renewables’ aim to lead the way in the transition to net zero, as we build out vital battery energy storage systems that will be capable of making the grid more resilient while maximising the opportunity to harness surplus renewable energy generated from onshore wind and solar generation in Northern Ireland.”

Objectives of the Acquisition 

SSE Renewables’ acquisition of the 100 MW battery storage project near Dungannon, County Tyrone, Northern Ireland, from Heron Energy is a strategic move with several key objectives:

Transition to net zero

This acquisition aligns with SSE Renewables' aim to lead the transition to net zero. The battery storage system will enhance the grid's resilience and optimise the potential to utilise surplus renewable energy from onshore wind and solar generation in Northern Ireland.

Supporting peak demand

The Derrymeen battery energy storage system (BESS) will be capable of storing up to 200 MWh of energy for flexible dispatch when needed for use by Northern Ireland homes and businesses at times of peak demand. This will ensure a reliable supply of energy during high-demand periods.

Enhancing energy storage capabilities

Battery storage technology plays a key role in unlocking the path to net zero because of its ability to hold and release energy when most needed. The acquisition of this project marks SSE Renewables’ first battery storage development in Northern Ireland. This acquisition will significantly contribute to the development of BESS projects in Ireland.
