Real-time generation cost guarantee - carbon price adder

August 1, 2019

Effective today, a carbon price adder will be added to the real-time generation cost guarantee (RT-GCG) pre-approved values. This change follows the OEB’s approval of proposed rate riders and charges for the federal carbon charge and the facility carbon charge in a federal carbon pricing application made by Enbridge Gas.

As a result, the IESO requires RT-GCG participants to provide a copy of both the:

  • Exemption certificate issued by the Canada Revenue Agency to facilities subject to the output-based pricing system
  • Invoice issued by Enbridge to facilities subject to the carbon pollution pricing system (by September 6).

This information should be sent to forwardmarkets@ieso.ca. The RT-GCG carbon price adder will be applied after this information is received.

The IMDC-55 is now posted on the Market Rules and Manuals Library page. The IMDC carbon price adder changes affect sections 5.3 and 5.4 of Market Manual 4.6.
