Construction has begun in Ireland on a project co-developed by Irish energy developers Lumcloon Energy and Hanwha Energy that will deploy a battery energy storage system with synchronous capacitors.
The energy storage system in the project has a capacity of 170MWh and will take two years to build at a cost of 130 million euros.
The low-carbon inertia provided by the synchronous capacitors in the project, coupled with the fast frequency response, backup power and other services provided by the battery energy storage system, will enable the project to cope with sudden changes in power supply and demand.
The two documents detail a battery energy storage project called "Shannonbridge b" with an installed capacity of 97.2MW and, if it were indeed the project, would have a duration of 1.75 hours. Although there is no widely agreed upon definition of long-duration energy storage (LDES), most descriptions tend to place long-duration energy storage systems lasting longer than four hours.
Lumcloon Energy and Hanwha Energy have partnered to deliver two 100MW/100MWh battery storage systems in Ireland, the first of which was commissioned in December 2020.
Ireland, like the UK, is one of the first movers in the European energy storage market, and the grid frequency response market provides a secure revenue service for energy storage projects. According to data provided by consultancy Delta-EE, by the end of 2022, 1.4GW of energy storage systems will be deployed in Ireland, of which 600MW will come online during the year.
In addition, Mitsubishi Electric Corporation recently revealed that it is supplying a 371MWh battery storage system to Irish energy developer ION Renewables.
