Long Lead-Time Resource Procurement

Ontario’s electricity sector continues to see a growing demand into the 2030s and beyond due to increasing industrial demand, data center growth and electrification. To meet these needs while maintaining flexibility, the IESO has taken a multi-pronged approach to secure energy and capacity resources under various term lengths.

Recent procurements have focused on securing medium term and long-term resources with 5- and 20-year term lengths respectively. The Long Lead-Time (LLT) Resource Procurement is intended for eligible resources with unique development considerations that require longer lead times for project development and longer-term lengths, aligned with the expected resource lifetime.

LLT Resource Procurement Updates

The IESO intends to begin engagement in early 2025. For further information about upcoming engagement sessions, please visit the IESO’s Long Lead-Time Resource Procurement Stakeholder Engagement webpage.
