    Banking information/treasury

    All transactions related to energy market and transmission settlements must remain separate, deposited into their respective Bank of Montreal accounts without netting energy market and transmission statements. The AESO will electronically transfer amounts owed to participants and customers on the cash settlement date based upon the separate energy market (pool) and transmission statements, without any netting to offset amounts that might be owed to the AESO (i.e. netting transmission and energy market).

    Credit procedures

    Under the ISO Rules, Section 103.3 Financial Security Requirements, market participants are subject to a financial review by the Alberta Electric System Operator. The intent of the financial review is to assess the creditworthiness of a market participant in order to determine if any unsecured credit limit should be granted. Please refer to ISO Rules Section 103.7 Financial Default and Remedies as well as ISO Tariff Section 5 Financial Obligations for Connection Projects and Section 13 Financial Security, Settlement and Payment Terms for additional market participant credit related information.

    For more information, please read the AESO Credit Procedures guide.

    The Credit Procedures Guide, developed to support the AESO’s implementation of the ISO Rule and ISO Tariff, provides transparency to market participants as it relates to the AESO business processes and practices for managing market participant prudential requirements.

    In the event of any discrepancies between the Credit Procedures Guide and the ISO Rules, the ISO Rules will take precedence. The granting of an unsecured credit limit for any market participant is at the discretion of the AESO.

    For information on the Credit Procedures Guide, or to provide feedback, please contact:

    Prudential pool price

    On the third business day of each month, the AESO will post a pool price for the current month, which will be used for the prudential requirement calculations for AESO market participants.

    The AESO will calculate the monthly pool price for prudential requirements using a multiplier applied to the Alberta forward electricity price. The use of a multiplier is to allow for price volatility differences between actual pool prices and forward pool prices. If the actual pool price reaches or exceeds the pool price used for AESO prudential requirement, the AESO may request additional financial security from a market participant at its discretion.

    For more information on the prudential pool price read the AESO Credit Procedures Guide.
