Long-Term 1 RFP and Expedited Process

LT1 RFP Updates

The IESO has now concluded the evaluation of Proposals for the LT1 RFP. Proposal evaluation yielded three Selected Proponents in the Non-Storage Category totalling 410.69 MW of Maximum Contract Capacity and 10 Selected Proponents in the Storage Category totalling 1,784.22 MW of Maximum Contract Capacity. Additional information is provided in the LT1 RFP Results Table.

The IESO is currently in the process of offering contracts to these 13 Selected Proponents and will, subject to the satisfactory completion of the pre-contractual requirements, enter into LT1 Contracts totalling 2,194.91 MW of Maximum Contract Capacity.

The IESO’s 2024 Annual Planning Outlook forecasts that Ontario’s total electricity demand will increase by 60 per cent over the next 25 years. Continuing work to build a reliable, affordable and sustainable electricity system is critical in ensuring communities will flourish, businesses have the confidence to invest and industries can decarbonize.

The IESO’s LT1 RFP – conducted along with other actions under the Resource Adequacy Framework – has successfully acquired the additional resources needed to meet Ontario’s electricity needs this decade. The procurement has resulted in competitive prices of new resources, strong community support, and significant Indigenous participation and equity ownership in projects.

The following LT1 RFP Communication Protocol is now in place:

During the competitive LT1 RFP process, the IESO must adhere to a very strict communication protocol, as set out in Section 3.4 in the LT1 RFP, 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 LT1 RFP, and Section 3.4 in particular, for the communication rules during the procurement process. Any correspondence received outside this process will be unanswered and further attempts to communicate outside of the LT1 RFP rules may result in disqualification under the LT1 RFP.

The LT1 RFP builds on the recently concluded Expedited Long-Term RFP (E-LT1 RFP) and the Same Technology Upgrades Solicitation,  demonstrating the important progress being made to meet Ontario’s reliability demands. More information is available in the IESO’s Resource Adequacy Update.

Procurement design and requirements have been and will continue to be shaped by input from stakeholders. Engagement for the next long-term procurement, the LT2 RFP, is ongoing and more information can be found on the IESO’s Long-Term 2 RFP webpage.

Expedited Process

The Expedited Long-Term RFP (E-LT1 RFP) and Same Technology Upgrades Solicitation were launched in 2022 to competitively secure new capacity through targeted and streamlined processes intended to bring resources into service before 2027.

The E-LT1 RFP acquired more than 1,100 MWs of new capacity to help meet system needs in the near and long term. This included 880 MW of capacity from electricity storage facilities scheduled to be in service no later than 2026, and representing a fleet five times that of Ontario’s current battery storage capacity.

It also acquired roughly 285 MW of expansions at existing natural gas facilities, providing a cost-effective and timely solution to Ontario’s immediate reliability needs. Natural gas will be necessary as a transitional resource to help maintain reliability as Ontario grows its storage fleet. The important operability characteristics of gas must remain available to Ontario’s power system as no like-for-like replacement is yet available. These procurements therefore strike the right balance between ensuring system reliability and setting the stage for the ongoing energy transformation. See the E-LT1 RFP Results Table.

The IESO’s Same Technology Upgrades Solicitation secured agreements with seven natural gas facilities for enhancements to existing equipment, which in total will provide 286 MW incremental capacity to Ontario’s system by mid-decade. See the Results Table.

Energy storage will be a key enabler in meeting Ontario’s future needs, and the Long-Term RFP, launching this fall, will build on these results, completing Ontario’s overall procurement of approximately 2,500 MW of storage that will be online/in-service toward the end of the decade.

More information is available in the IESO's June 2023 Resource Adequacy Update.
