Project-CAES Larne, NI

Our most advanced energy storage project deploying compressed air energy storage (CAES) technology. This facility will generate up to 330 MW of power for periods of up to 6 hours. It will create demand of up to 200 MW during its compression cycle. The project involves the creation of two storage caverns within salt deposits which are a feature of the east Antrim coastal areas of Northern Ireland. These caverns will be located at depths of greater than 1400 m below ground.

The facility will be highly responsive and will be capable of providing a range of tools to system operators in their management of the transmission grid.

Project-CAES Larne, NI has been designated as a European Project of Common Interest (PCI) and has been recommended for grant funding of up to €6.5million under the Connecting Europe Facility.

The project has been designed to allow its replication at other suitable sites in the United Kingdom and the European mainland.

Our technology partners are Dresser-Rand.

In December 2015, we submitted a planning application and Environmental Impact Assessment (EIA) for Project-CAES Larne, NI to Strategic Planning Division.
