IESO Sanction

July 21, 2022

On July 6, 2022, the IESO was sanctioned by the Market Assessment and Compliance Division (“MACD”) of the IESO for imposing intertie flow limits based on internal transmission constraints, thereby affecting the market schedule in a way not authorized by the Market Rules. The IESO is treated as if it were a market participant for the purpose of compliance with its obligations under the Market Rules and is subject to MACD’s jurisdiction for that reason.

MACD determined that, in taking internal transmission constraints into account in setting these intertie flow limits, the IESO violated sections and of Chapter 7 as well as section 7.5.1 of Appendix 7.5 of the market rules. As a result of these breaches, the following sanctions were issued to the IESO: (i) a letter of non-compliance; and (ii) a financial penalty in the amount of $10,000.

For additional information on this enforcement outcome please see MACD’s Sanctions page.
