Marguerite Lake Energy Project

A Powerful Location

Ready FOR ACTION

A rare combination of existing infrastructure, exceptional geology, access to natural gas and secured land — creating an exceptional location for long-duration compressed air energy storage.

Phase 1 Capacity
320 MW
Future Expansion
640 MW
Energy Storage Duration
48 HOURS+
Energy Storage
15,360 MWh

A Prime location with Four Strategic Advantages

  1. EXISTING GRID INFRASTRUCTURE

    ~800m

    Planned Interconnection

    • • Adjacent to Marguerite Lake Substation (operated by ATCO)
    • • Existing 240 kV transmission infrastructure with available substation capacity
    • • AESO accepted System Access Requests for Phase 1 and Phase 2, as well as for the BESS

  2. EXCEPTIONAL SUBSURFACE GEOLOGY

    ~1000m

    TO Top of SALT

    • • Lotsberg Salt Formation
    • • ~200 m expected salt interval
    • • Selected for solution-mined cavern development
    • • Expandable for future phases
    • • Approvals in place to store Compressed Air, Natural Gas and Hydrogen

  3. NATURAL GAS INFRASTRUCTURE

    ~14 km

    TO NATURAL GAS CONNECTION

    • • Preferred connection concept via the Leming Lake Lateral Sales Loop
    • • Route leverages cleared and previously disturbed right-of-way
    • • Approved PLA disposition for the pipeline route corridor

  4. ADVANTAGED SURFACE LOCATION

    3 km

    NO RESIDENTS OR LANDOWNERS

    • • Crown land
    • • Previously disturbed / cleared areas
    • • No residences or landowners within 3 km
    • • Required land and subsurface tenure secured

A Geological Advantage

Deep. Stable. Ideal.

Deep beneath the site lies the Lotsberg Salt Formation — an ideal natural storage medium for CAES. Its depth, thickness and quality provide the perfect setting for solution-mined caverns that safely store compressed air under pressure.

Subsurface lease amended by Alberta Energy to also enable natural gas and future hydrogen storage.
