IESO Issues Letter of Non-Compliance and Imposes Sanctions
December 2, 2021
On September 7, 2021, pursuant to Chapter 3 of the Market Rules, the IESO issued a letter of non-compliance to Alectra Utilities Corporation (“Alectra”) and imposed a financial penalty in the amount of $269,000 for breaches of Chapter 1, section 11.3.1 and Chapter 6, sections 4.1.1.10, 7.1.1, 7.1.7 and 11.1.2 of the Market Rules.
The investigation revealed that instrument transformer checks were not conducted within the timelines provided for in the Market Rules, and that an instrument transformer had been malfunctioning for an 11-year period, May 4, 2005 to March 30, 2016, resulting in a significant underpayment by Alectra and a corresponding overpayment by other market participants. The majority of the under and overpayments were reversed through the IESO’s resettlement process.
The IESO acknowledges that the substantive breaches in this matter occurred while Alectra's predecessor(s) were the registered market participants for the malfunctioning metering installation. The IESO is satisfied that Alectra’s fulfillment of all ordered actions resolves all matters which were the subject of this investigation. More details can be found on the IESO's website.
