Corre Energy moves forward with a large compressed air storage project in the Netherlands – EQ Mag
Utility Eneco and Corre Energy have signed an agreement for the latter to deploy a 320MW, 84-hour duration compressed air energy storage system (CAES) in Groningen, the Netherlands.
Dublin-based Corre Energy plans to build the facility in a salt cavern in the municipality of Zuidwending. Exploratory drilling will start in 2023 to assess if the site is suitable for compressed air storage, and the installation of the entire system is expected to be completed by 2026.
The planned system will use up to 220MW of power to convert excess electricity into compressed air and store it in the cavern. When the energy is needed, the compressed air will be expanded through a turbine which will generate electricity with a maximum power of 320MW.
The system can discharge at this power for three and a half days, of 84 hours, which equates to a potential 26,880MWh or 26.88GWh energy storage capacity.
However, Corre’s corporate affairs consultant Kieran McKinney told Energy-Storage.news that, although the calculation is a useful proxy, because the system is fuel-based “….the implied energy storage capacity cannot simply be directly compared to battery capacity”.
“With this storage duration, the facility will be able to arbitrage over a rolling two-week period, as there will be both daily and weekly demand cycles, combined with 2-5 days weather cycles,” he said.
