Vancouver, British Columbia — December 22, 2025 — Leads & Copy — Aegis Critical Energy Defence Corp. has entered a legally binding agreement with Seetel New Energy Co. Ltd. (Taiwan) through the formation of Cordelia BESS Inc., to participate in Ontario’s grid-scale energy storage market, according to a release.
Cordelia BESS Inc. submitted a proposal on Thursday, December 18, 2025, in response to the Independent Electricity System Operator’s (IESO) Long-Term 2 (LT2) Request for Proposals – Capacity Stream (C1). The submission contemplates the potential development of a battery energy storage system (BESS) project with an indicative size of approximately 90 MWh, subject to the IESO’s evaluation process and the satisfaction of all applicable commercial, regulatory, and contractual conditions.
The project site is subject to an agreement with the land holders and is located adjacent to an existing Festival Hydro substation in Ontario. The project remains at a development and procurement participation stage, and no contract award, revenue, or commercial operation is assured. Any advancement of the project is contingent upon the IESO’s procurement process, the execution of definitive agreements, and receipt of all required approvals.
The LT2 Capacity Stream is part of the IESO’s long-term electricity planning framework designed to secure additional dispatchable capacity to support system reliability and meet forecasted demand growth associated with electrification, population growth, and industrial development. Battery energy storage systems are among the resource types eligible to participate in the LT2 procurement, given their ability to provide flexible capacity and grid support services.
Publicly available IESO planning materials indicate that Ontario electricity demand is expected to grow significantly over the coming decades, with forecasts projecting material increases in peak demand and total system requirements by mid-century. The LT2 procurement process is intended to competitively evaluate eligible resources capable of contributing to system reliability under these long-term conditions.
AEGIS cautions that participation in the LT2 procurement does not imply selection, preference, or endorsement by the IESO. All proposals are subject to a confidential, competitive evaluation process conducted independently by the IESO in accordance with its published rules and procedures.
The Independent Electricity System Operator (IESO) is the Crown corporation responsible for operating and planning the electricity system and wholesale electricity market in the Province of Ontario. Established under the Electricity Act, 1998, the IESO manages Ontario’s bulk electricity system and ensures the reliable supply of electricity across the province.
