For a segment (on-peak or off-peak) of a month for a Company, the price paid to the supplier and appearing in the applicable supplier contract is the average of the supplier’s own approved Bids for all blocks of the Product (corresponding to the given segment, month, and Company) and for all blocks of Combinations that include that segment and month for that Company.

For example, the price paid to a supplier for ComEd June 2019 on-peak will be a single number that reflects the weighted average of any approved bids for the supplier for ComEd June 2019 on-peak as well as the annual (June 2019-May 2020) on-peak combination.  As another example, the price paid to a supplier for AIC July 2020 off-peak will be a single number that reflects the weighted average of any approved bids for the supplier for AIC July 2020 off-peak, for the AIC July-August 2020 off-peak combination, as well as for the annual (June 2020-May 2021) off-peak combination.

Please note that for purposes of preparing the applicable supplier contracts, the Companies have access only to the weighted average price for each month and segment, and not to the Bids on individual blocks used to calculate such average prices.
