Public event on Tinnycross battery energy storage plan

SSE is hosting a public consultation evening on Thursday, May 8, for the proposed Tinnycross battery energy storage system (BESS), to be located north-east of Tullamore.

The event will be held at St Mary’s Youth and Community Centre, Harbour Street, Tullamore, from 2.30pm to 8.30pm

Tinnycross BESS (formerly known as Thornsberry BESS) is a proposed, grid-scale 120MW/240MWh battery energy storage system to be located on a greenfield site. The project would be capable of powering the equivalent of over 115,000 Irish homes for up to two hours at a time, during times of peak demand.

Tinnycross BESS would also help balance the national grid, provide backup energy when the wind isn’t blowing, or the sun isn’t shining.

The project will involve the payment of development contributions and commercial rates.

Members of the SSE Renewables project team will be available at the consultation evening to provide more information, answer questions, and gather feedback. In addition to the in-person event, project materials and an online feedback form will be available on the project website from May 8 until May 29. Residents can access these materials and submit their feedback at www.sserenewables.com/tinnycross during this period.

Tinnycross BESS was acquired by SSE in late 2024 as a fully consented battery energy storage project.

A revised planning application will be submitted to Offaly County Council to reflect updates in the design of the project.

Subject to receiving the necessary planning consent and a final investment decision by SSE, the project could enter construction and be operational by the end of the decade.
