STP-51: Can you provide an overview of the product from the 2016 capacity procurement event for Ameren Illinois Company (“AIC”)? Were bidders required to identify the capacity resources as part of the RFP?

Under the 2016 capacity procurement event for AIC, there was no requirement for identifying resources within the proposal submitted in response to the Standard Products RFP. However, the winning bidder was responsible for the registration of the Planning Resources in MISO and for all obligations associated with such Planning Resources to ensure that the Zonal Resource Credits (“ZRCs”) delivered to AIC have good and marketable titles.

The product for bid was annual ZRCs, as such term is defined in MISO’s Business Practice Manuals and MISO’s Open Access Transmission, Energy and Operating Reserve Market Tariff for a given planning year. A target of ZRCs to be procured was established as a given percentage of AIC’s requirement in that planning year.   A winning bidder would be required to deliver the contracted quantity of ZRCs by submitting the appropriate transactions in the Module E Capacity Tracking Tool. The amount paid to the winning bidder was the average of the winning bidder’s own approved Bids for all ZRCs in that planning year, in $/MW-Day, multiplied by the number of ZRCs delivered, multiplied by the number of calendar days in the Planning Year. If any of the ZRCs were not located in Local Resource Zone 4, which is the zone in which AIC capacity obligations reside, the payment to the winning bidder was adjusted as follows. If the clearing price of the MISO Planning Resource auction for LRZ 4 was greater than the clearing price of source zone for the ZRCs, then the payment would be reduced by the difference in the clearing prices between the two zones multiplied by the quantity of ZRCs. Conversely, if the clearing price of the MISO Planning Resource auction for LRZ 4 was less than the clearing price of source zone for the ZRCs, then the payment would be increased by the difference in the clearing prices between the two zones multiplied by the quantity of ZRCs.
