Organization Registration and Participant Authorization

Organizations must be authorized by the IESO if participating in the IESO-administered markets or programs, have a physical facility connecting to the IESO-controlled grid, or to become a service provider.

Online IESO

Online IESO is a web-based registration system, allowing organizations to complete a variety of interactive business tasks, and post information to the IESO in a safe, secure and efficient manner.

Facility Registration

Organizations must register a physical facility (generation, load, demand response, transmission and distribution) that is connecting to the IESO-controlled grid or will be participating in the IESO-administered markets or programs.

Meter Registration

Within Ontario, all energy bought or sold by market participants must be measured and recorded by registered revenue metering installations—the IESO, market participants and metering services providers all play a role in the revenue metering process.
