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).

Prudential pool price

At the start of each month, the AESO will post the forward power price for the month or balance of the month, adjusted by adding a multiplier to the price (“Prudential pool price”).  The use of a multiplier is to allow for price volatility differences between actual pool prices and the forward price.

The AESO use both actual pool prices and the Prudential pool price (for balance of month) to calculate prudential requirements for market participants. 

Please note that Prudential pool prices will change throughout the month due to changing market conditions.  To obtain up-to-date Prudential pool prices, please contact Credit@aeso.ca

2022 prudential pool price

** Effective May 1, 2022, the AESO will no longer be publishing the prudential pool prices. For up to date forward prices, please contact Credit@aeso.ca.
