The usage fee of $1.2402/MWh for domestic customers will be applied to each market participant’s allocated quantity of energy withdrawn (AQEW) from the IESO-controlled grid, plus the embedded generation volumes reported by each LDC to the IESO on a monthly basis.

The usage fee of $1.0115/MWh for export customers will be applied to each market participant’s scheduled quantity of energy withdrawn (SQEW).

Smart Metering Entity Charge

The IESO operates as the Smart Metering Entity (SME) under licence by the Ontario Energy Board. The SME is responsible for the implementation and operation of the province’s Metering Data Management/Repository (MDM/R), which manages consumption data for residential and small business smart meters to support time-of-use billing. The current Smart Metering charge of $0.57 per meter per month was approved by the OEB in a decision issued on March 1, 2018 and is levied and collected by the licensed electricity distributors from Residential and General Service <50kW customers.
