Medium-Term RFP

The IESO will continue to run a series of cadenced medium-term request for proposals (RFPs) every two to three years, with flexible five-year commitment periods to secure resources with expiring contracts. Future medium-term RFPs will continue to evolve based on system needs and will likely see increased resource eligibility and competition. Procurement designs will continue to be shaped by input from stakeholders through IESO’s ongoing engagements.

The second medium-term procurement (MT2 RFP) will aim to re-commit existing resources with contracts expiring over the 2026-2029 period, which are best positioned to cost-effectively meet energy and capacity needs emerging late this decade and into the early 2030s. The MT2 RFP will include both capacity and energy streams, and proposals will be evaluated on price.

MT2 RFP Updates

The IESO has now concluded the evaluation of Proposals for the MT2 RFP. The MT2(e) RFP (Energy Stream) yielded 19 Selected Proponents, totalling 994.97 MW of Maximum Contract Capacity. The MT2(c) RFP (Capacity Stream) yielded nine Selected Proponents, totalling 2,007.12 MW of Maximum Contract Capacity. Additional information is provided in the Results Table.

The IESO is currently in the process of offering contracts to the Selected Proponents and will publish a final Results Table confirming the executed contracts and associated prices once contracts have been fully executed in June of 2025.

The following MT2 Communication Protocol remains in place

During the competitive MT2 RFP process, the IESO must adhere to a very strict communication protocol, as set out in Section 3.5 of the MT2(c) and MT2(e) RFP, as applicable, to maintain the integrity and fairness of the process for all participants. In cases of breach of the communications rules, the IESO may, in its Discretion, disqualify a Proponent or revoke the status of a Proponent, as the case may be. We encourage you to review the MT2(c) and MT2(e) RFP, as applicable, and Section 3.5 in particular, for the communication rules during the procurement process. Should you have a question, comment or require clarification, please submit your question or comment by email to MT2.RFP@ieso.ca. Any correspondence received outside this process will be unanswered and further attempts to communicate outside of the MT2 RFP rules may result in disqualification under the MT2 RFP.

Any general enquiries regarding the MT2 RFP can be sent to MT2.RFP@ieso.ca.

The IESO has concluded the first medium-term RFP, and has entered into MTC I Contracts, each with a five-year term, with one wind and four natural gas facilities. Together these facilities contribute more than 700 MW of capacity to the system, ensuring ongoing value from previous investments in supply. See the MT1 RFP Results Table.

This supply will be available between 2024 – 2026, at a lower cost than previous contracts. This procurement complements other IESO supply acquisition activities to meet reliability targets over the same timeframe.

The IESO will continue to run a series of cadenced medium-term RFPs every two to three years, with flexible five-year commitment periods in order to secure resources with expiring contracts. Future medium-term RFPs will evolve based on system needs and will likely see increased resource eligibility and competition. Procurement designs will continue to be shaped by input from stakeholders through the Resource Adequacy Engagement, as well as other IESO assessments and engagements.
