Why Larne?

It is the only place in Northern Ireland, and one of the few places in the United Kingdom, which has salt deposits potentially suitable for storing compressed air.

Safety First

CAES has been tried and tested as a reliable, safe and efficient way of contributing to the generation of electricity in Germany and the United States of America for more than 30 years.

The Health & Safety of the public, and our employees and contractors is of paramount importance to Gaelectric and the NI Project Team.

All works will be carried out in accordance with the Construction Design Management Regulations and the Borehole Sites and Operations Regulations.


Should the CAES project go ahead, Gaelectric is committed to spending one quarter of the total project investment locally, that is, approximately £44 million of some £175 million. It will create up to 200 jobs, peaking in the construction phase.

A community fund from the Project will be used to support community groups working in Larne and the surrounding areas, to benefit those who are trying to make a real difference in our community.

An operating CAES facility will provide many benefits across Northern Ireland, including:

  • Lower overall energy costs for households and businesses
  • Maximising the use and value of Northern Ireland’s indigenous renewable energy
  • Reducing Northern Ireland’s reliance on imported fossil fuels such as coal and gas by
  • Reducing Northern Ireland’s carbon footprint

The project will enable a faster and more efficient integration of renewable energy onto the grid, thus providing indirect employment benefits for a wide range of businesses involved in the development, construction and operation of renewables facilities and grid management systems.

A CAES facility at Larne will place Northern Ireland at the forefront of the development of the Smart Grid in Europe.
