Ontario’s electricity system is changing. The market of the future must accommodate a range of new resource types, often with different attributes and operating characteristics than our existing fleet. Given the ongoing transformation of the system, the market must be flexible enough to support the integration of new sources of supply, accommodate changing policy imperatives and consumer preferences, stimulate investments in new supply as required, and deliver the most economically efficient outcomes.

Through our Resource Adequacy Framework and our Enabling Resources Program, the IESO is taking steps to expand, enhance and modernize Ontario’s power system.
