SSE Expands Irish Battery Portfolio with 120-MW Acquisition

• SSE Renewables amplifies its green energy mission by acquiring a 120-MW battery project in Offaly, propelling Ireland's storage capacity and paving the way for a sustainable future.

SSE Renewables has acquired a 120-MW/240-MWh battery energy storage project in County Offaly, Ireland, from UK-based Low Carbon, enhancing its battery development portfolio on the island. The Thornsberry project has received planning consent and features a grid connection for 120 MW capacity. If a final investment decision is reached, construction could commence soon, with operations potentially starting by the end of the decade.

This acquisition boosts SSE’s total battery pipeline in Ireland to 300 MW within a broader 1.8-GW pipeline that spans both Ireland and the UK. Low Carbon, which initiated the Thornsberry project in 2018, currently contributes to 20% of Ireland's energy storage capacity.

How does SSE's acquisition of Thornsberry impact Ireland's energy storage landscape?

• Enhanced Energy Storage Capacity: With the acquisition of the Thornsberry project, SSE's total battery capacity in Ireland increases significantly to 300 MW. This bolsters the energy storage infrastructure critical for balancing renewable energy generation with consumption.
• Strategic Location: Thornsberry's location in County Offaly positions it advantageously within Ireland's grid system, potentially facilitating easier integration of renewable energy sources and providing grid stability in the region.
• Regulatory Support: The project has already received planning consent, indicating that regulatory pathways for energy storage projects in Ireland are becoming more streamlined. This could encourage further investments in energy storage technology, contributing to Ireland's green energy agenda.
• Renewable Energy Integration: The addition of a 120-MW battery storage facility will enhance the ability to store excess energy generated from wind and solar projects, addressing intermittency issues associated with renewable energy sources. This, in turn, supports Ireland's transition towards a more sustainable energy system.
• Potential Economic Benefits: Construction of the Thornsberry project could create local jobs and stimulate the economy in County Offaly. Additionally, operational phases may provide long-term employment opportunities and economic development throughout the region.
• Contribution to National Goals: This acquisition aligns with Ireland’s commitment to achieving a significant reduction in carbon emissions by 2030. Energy storage plays a crucial role in supporting the national grid while enabling higher penetration rates of renewables.
• Increased Competition: SSE's entry into the energy storage market can foster competition, leading to more innovation and efficiency within the industry. This may drive other energy companies to invest in storage solutions, further expanding the market.
• Collaboration Opportunities: As SSE expands its energy storage capabilities, there may be opportunities for partnerships with other renewables and technology firms. Collaborations can enhance technological advancements and optimize battery storage solutions.
• Long-Term Stability for Energy Supply: The establishment of robust energy storage solutions like Thornsberry will contribute to a more resilient energy supply, reducing reliance on fossil fuels and ensuring a stable electricity supply for consumers.
• Public Awareness and Support for Renewables: Projects like Thornsberry can help raise public awareness of renewable energy benefits. As communities see tangible projects and local investment, public support for renewable energy initiatives may increase, aiding future projects.
• Alignment with European Energy Policies: This acquisition supports broader European Union objectives for increasing energy independence and fostering renewable energy development, positioning Ireland as a proactive participant in regional sustainability efforts.
