Ontario IESO procures 640MW energy storage in LT2 Request for Proposals

AI-summarised brief · reviewed before publication

Ontario's Independent Electricity System Operator (IESO) has secured 640MW of new energy storage capacity through three projects selected under the capacity stream of the Second Long-Term Request for Proposals (LT2). The projects, which include First Nations partners with at least 50% equity ownership, received strong municipal support and are expected to begin commercial operations by 1 May 2030. The procurement has secured over 1,750MW of new electricity supply through 16 projects across Ontario, with a weighted average price 36% lower than the government's earlier Expedited-LT1 capacity procurement.

💡 Why It Matters

  • · The significant cost savings of the LT2 procurement, at 36% lower than previous tenders, underscores the potential for energy storage to drive down costs and increase efficiency in Ontario's energy market.
  • · This achievement highlights the importance of community-led projects in achieving direct economic benefits for local communities.
