Sustainable infrastructure investor, NTR, has announced the deployment of two battery energy storage systems in Co. Wexford, Ireland.

The 9MW BESS situated in Gorey entered the Delivering a Secure, Sustainable Electricity System (DS3) service for Ireland’s transmission system operator (TSO), EirGrid, in April 2023; following this, the 16MW BESS in Avonbeg is due to enter the DS3 market this April.

Both sites have also achieved capacity market contracts.

The BESS systems respond in 150 milliseconds to balance the grid by discharging electricity, according to the company.

These balancing mechanisms are hoped to increase the volume of renewable energy on the Irish grid.

“I am pleased to announce the successful testing of DS3 Systems at our Gorey and Avonbeg battery storage projects in Ireland,” said Joe Dalton, NTR Plc’s director of asset management.

“This cutting-edge technology enables us to contribute to the frequency stability of the Irish grid, facilitating increased renewable energy deployment. NTR's batteries can respond to changes in frequency faster than 150 milliseconds.

“This is the highest frequency response requirement in the world. Our team worked tirelessly to develop and install these systems, which can be replicated globally, and is testament to NTR's commitment to securing a greener future.”
