As the operator of Ontario’s electricity system, the IESO seeks input from system participants and stakeholders to ensure that province-wide and community-level energy requirements are met efficiently and effectively. The EDA works closely with the IESO to provide valuable input on a range of electricity system and market issues. Most recently, the EDA has launched a committee to provide valuable input on IESO’s Market Renewal Program.
