Project
From salt production to large-scale storage of power and fuels, we are turning one geological asset into a multi-purpose site.
It begins with Long Duration Energy Storage (LDES) for a world class wind resource, making on-demand clean energy possible.
Compressed Air Energy Storage (CAES)
Fischells Salt Dome‘s dual role in storing and generating clean energy will make it a cornerstone of a resilient and flexible energy system. It will provide firming power for renewables, stabilize the grid, and unlock export potential to Europe and North America.
The first phase of development at Fischells will use compressed air energy storage. When wind farms produce more electricity than the grid needs, the surplus can be stored underground as compressed air. When demand rises, the air is released to generate electricity. This creates reliable, on-demand power that strengthens Atlantic Canada’s grid and boosts our long-term energy security.
Other Fuels
Future phase development at Fischells includes the potential for more than 20 caverns that can store a variety of potential energy carriers – from traditional fuels such as oil and natural gas to meeting growing clean fuels demand through hydrogen storage.
Salt Recovery
Developing caverns in the Fischells Dome also produces a valuable by-product: high-purity salt. This salt can be recovered for industrial use and export, creating an added revenue stream for Newfoundland and Labrador. It’s another way to generate value without expanding the project’s footprint.
Unlike conventional storage options, Fischells enables:
Dual-Mode Energy Infrastructure
The dome will be both a clean energy generation and storage facility: storing excess wind power as compressed air for rapid delivery back to the grid, while also providing long-duration storage for a variety of additional energy sources and fuels.
Maximum Renewable Energy Utilization
By converting excess wind power into storable energy, Fischells can increase wind-farm capacity by up to 40 percent, eliminate curtailment, and deliver around-the-clock clean power to unlock the full value from Atlantic Canada’s wind resources.
Strengthened Energy Security
Fischells can serve as a strategic reserve, guarding against supply shocks, stabilizing prices, and strengthening Eastern Canada’s role in global energy security and affordability.
High-Impact Economic Development
Fischells can deliver meaningful community and workforce benefits through Indigenous partnerships, local procurement, apprenticeship opportunities, supplier development, and regional training. The project is expected to create approximately 800 construction jobs and 70 long-term operations jobs, with employment opportunities across construction, operations, maintenance, environmental services, transportation, fabrication, monitoring, and technical trades.
At a Glance
