1. SSE Renewables acquires 100 MW / 200 MWh battery storage project in Northern Ireland from Heron Energy.
2. The Derrymeen battery energy storage system would be the largest in Northern Ireland, capable of storing energy for flexible dispatch.
3. SSE Renewables aims to lead the way in the transition to net zero with investments in battery storage projects to support renewable energy generation.
SSE Renewables has acquired a 100 MW / 200 MWh battery storage project in Northern Ireland from Heron Energy. The project, called Derrymeen, will be the largest battery storage facility in Northern Ireland once completed. It will be capable of storing up to 200 MWh of energy for flexible dispatch during times of peak demand, providing backup energy to the equivalent of over 135,000 homes in Northern Ireland for up to two hours. The project is part of SSE Renewables’ Net Zero Acceleration Programme, aiming to support the transition to net zero by investing in low carbon energy infrastructure, including battery storage technology.
The Derrymeen project is SSE Renewables’ first battery storage development in Northern Ireland and is expected to bring significant economic and job creation benefits to the region. Construction could start early next year and be operational by the end of 2026. The project has secured planning consent and will connect to Northern Ireland’s electricity grid via an underground cable. SSE Renewables is also developing other battery projects in Ireland and Great Britain as part of its efforts to lead the transition to net zero and enhance the resilience of the grid.
