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).
