    Pool Price Errors

    On Friday, October 7, 2016, the AESO identified and immediately corrected a market system issue that could impact the System Marginal Price under certain conditions.

    The issue had been inadvertently introduced during a system update on Wednesday, August 10, 2016. An AESO review of Pool Prices since that point in time found the Pool Price for the following seven hours need to be corrected:
