Iberdrola Renewables has powered up its first commercial-scale Battery Energy Storage System (BESS) in the east of Ireland after an investment of €28m.

Iberdrola said its 50MW Gorman BESS in Co Meath will provide system services to EirGrid for six years, contributing to the security and sustainability of the electricity network in Ireland.

The project is made up of more than 4,000 battery modules spread across 16 battery containers on a site the size of a football pitch and it will help balance supply and demand and ensure additional green electricity is available when needed,.

The Gorman battery project marks a number of firsts for Iberdrola as it is the first operational commercial-scale battery anywhere in the world and the company's first renewables construction project in Ireland for more than 25 years.

Iberdrola is also constructing a smaller 3MW BESS at Barnesmore windfarm in Co Donegal, with pre-construction activities also progressing on the consented repowering of Barnesmore windfarm.

It also had expansion plans for its Gorman BESS to double its capacity to 100MW.

Planning is also underway to deliver three offshore wind projects - Clarus, Shelamere and Inis Ealga Marine Energy - with a total potential capacity of 3GW in partnership with DP Energy.

This would be enough green electricity to power the equivalent of more than 2.8 million homes.

Charlie Jordan, CEO for UK and Ireland, said the new battery site is a major milestone not just for Iberdrola in Ireland, but for Iberdrola globally, with the powering up of its first-ever operational battery project of this size and scale.

"Ireland has set out major ambitions to halve emissions by the end of this decade and achieve net zero by no later than 2050, so investing in the infrastructure needed to help turn that vision into reality is vital if progress is to stay on track," he said.

"That means new green generation - both onshore and offshore - supported by innovative technology like our Gorman Battery Energy Storage System, which will support the stability and reliability of the network and ensure that clean energy is available when it's needed," he added.

In May, Iberdrola announced it was exiting the Irish gas and electricity retail market.

It said the move follows an internal strategic review that found market conditions and pricing were a barrier to its planned growth and ambitions. The firm added that the situation has been exacerbated in recent months by the unprecedented increase in global wholesale energy costs.
