Aegis Critical Energy Defence Corp. has formalised the creation of Cordelia BESS Inc., a project company incorporated in Ontario, in partnership with Taiwan-based Seetel New Energy Co. Ltd. The initiative aims to enter Canada’s grid-scale energy storage market, through a proposed project under the LT2 Capacity Stream programme led by Ontario’s Independent Electricity System Operator (IESO).

A 90 MWh project in preliminary stage

Cordelia BESS submitted a proposal on December 18 in response to the LT2 “Capacity Stream (C1)” call for proposals. The project outlines the development of a battery energy storage system (BESS) with an indicative capacity of approximately 90 megawatt-hours (MWh). It is located near a substation operated by Festival Hydro, on a site already contractually secured with landholders.

The company noted that the project remains under development. No contract, revenue, or commercial operation is assured at this stage. Its advancement will depend on IESO’s evaluation, execution of definitive agreements, and receipt of all required regulatory approvals.

A market driven by demand growth

The LT2 programme is part of IESO’s long-term planning framework to secure additional dispatchable capacity in response to expected energy demand growth. This increase is driven by electrification, population expansion, and industrial development in Ontario.

Battery energy storage systems are among the eligible resources in this call for proposals due to their ability to offer flexible grid response and support reliability. IESO forecasts substantial growth in peak demand and total system needs by 2050.

Competitive process and no award guarantee

Aegis stated that participation in the LT2 process does not imply any preference, selection, or endorsement by IESO. Proposals are subject to a confidential competitive evaluation, conducted under IESO’s official rules and procedures.

The final selection will depend on technical, commercial, and regulatory criteria defined by IESO. If successful, the Cordelia BESS project would mark Seetel’s first entry into the North American energy storage market, in partnership with a Canadian player focused on critical infrastructure.
