The Independent Electricity System Operator (IESO) works at the heart of Ontario's power system. The IESO delivers key services across the electricity sector including: managing the power system in real-time, planning for the province's future energy needs, enabling conservation and designing a more efficient electricity marketplace to support sector evolution.

Capacity auction high-level design released
After extensive stakeholder consultation, the high-level design for the Market Renewal Program’s incremental capacity auction (ICA) is now available. The ICA will help meet needs at the lowest cost by encouraging greater competition in securing resources and giving the IESO the flexibility to adjust to changing supply-demand dynamics.
