Why Mountain Gravity?
Renewable energy is intermittent by nature, requiring innovative storage solutions for large-scale adoption. MGES uses natural elevation changes to store and release energy efficiently and sustainably.
How it works: Large masses (like railcars) are moved up a mountain during times of excess energy, then released downhill to generate power during periods of high demand.
Alberta’s Advantage
By leveraging the unique geography of Alberta’s Rocky Mountains, Gravity offers a scalable, cost-effective answer to the “excess renewable energy” problem.
Feasibility
- Promising sites identified in Crowsnest Pass and Nordegg regions
- Potential to reactivate historical rail assets with modern electric freight trains
- Scale implementation: 5,000 MWh storage facility for under $1B CAD*
- Estimated Levelized Cost of Storage (LCOS): $56.27 per MWh*
*Excludes land agreements. Internal evaluation, 2025.
