Business Plan

With demand for electricity on the rise, additional resources required to meet growing needs, and new technologies providing options to meet those needs, the power system is facing some unique challenges in the coming years. The IESO’s 2023-2025 Business Plan positions the organization well to deliver the reliable, resilient and efficient grid and market on which Ontarians rely. This plan sets out our priorities in a number of key areas, which include ensuring resource adequacy, enabling new resources, fostering innovation, exploring pathways to decarbonization, and advancing market renewal.

The IESO has held its revenue requirement below inflation for the previous five years, but targeted investments in resources to support this expanded effort are now required. As always, the IESO is committed to finding efficiencies and pursuing the most economical solutions, including introducing more competition, enabling more resources to participate in the market, and using more flexible procurements to meet changing system needs.
