Long-Term RFP

Resource Acquisition

The 2021 Annual Acquisition Report (AAR) signalled the IESO’s intent to launch a Request for Proposal (RFP) for at least 1,000 MW in fall 2022 to address multiple reliability needs.

The Long-Term RFP (LT RFP) will seek resources that can be in service between 2026 and 2028 to address global and regional needs. This procurement is part of the IESO’s broader Resource Adequacy Framework – an enduring approach to identifying the type of acquisition activity to use to resolve system needs. The framework contemplates a multi-pronged approach to secure resources, generally based on the length of the contract term.

The Long-Term RFP engagement plan outlines the objectives, approach, timeline and considerations for engaging stakeholders and conducting outreach to other targeted audiences throughout the development of the LT RFQ and RFP. This engagement plan may be subject to review and updates as the process evolves. All comments and enquiries on this engagement can be directed to
