IESO Licence

The licence issued by the Ontario Energy Board (OEB) authorizes the IESO to direct the operation of the transmission system in Ontario, facilitate the IESO-administered markets and carry out its duties as defined in the Electricity Act, 1998.

The IESO filed an application for a licence amendment with the OEB on March 25, 2024. The application and other documents which form the record of the proceeding are available on the OEB’s web site (Case Number EB-2024-0128).

Smart Metering Entity Licence

The Government of Ontario designated the IESO as the Smart Metering Entity (SME) in 2007 to support its Smart Metering Initiative. The SME is responsible for overseeing the meter data management repository (MDM/R) and processing smart meter consumption data from MDM/R service recipients in Ontario to support time-of-use (TOU) billing.

The SME is authorized by a licence issued by the OEB, valid until December 31, 2026.
