Question: Can you please explain how DZSF is derived?

Answer: Current DZSF are available in the Historical Hourly Loads file on the Information Website. They are calculated in column K of the ‘Capacity PLC and DZSF’ tab: https://www.aes-ohioauction.com/LoadData.aspx

Cells M2 and M3 of the ‘Capacity PLC and DZSF’ tab represent the daily capacity obligation for the DAYTON zone.  DZSF is calculated by dividing the daily capacity obligation for the DAYTON zone (found in cells M2 and M3) by the daily Capacity PLC (found in column I).

1. The Summer 2021 Weather Normalized RTO Coincident Peaks (MW) for the DAYTON zone is provided yearly by PJM in October. 
2. Wholesale LSE’s (i.e. municipalities, cooperatives) are then subtracted from that number provided by PJM. 
3. This amount (e.g. cells M2 and M3 on the ‘Capacity PLC and DZSF’ tab) represents the daily capacity obligation for the DAYTON zone. 
4. AES calculates the sum of the PLCs for each account served by the retail supplier and reports this to PJM.  PJM  will then scale the supplier PLCs proportionally to the DAYTON obligation.    Instead of aggregating by retail supplier, the 2021 AES Load Data aggregates by class but with the same logic.

Question: We understand that Wright Patterson Air Force Base (WPAFB) has the ability to choose the SSO or another competitive supplier. We were wondering if WPAFB is currently on or off SSO. Moreover, we would highly value any information you could provide on any long-term power supply contracts that WPAFB has with a competitive supplier.

Answer: Wright Patterson Air Force Base is currently an SSO customer and they have the ability to choose a competitive supplier.  AES cannot share information about contracts that individual customers may or may not have with 3rd party suppliers.

Question: Can you please confirm that the product of the following three items equals the PJM settlement data called load without losses? 1) hourly load 2) the AES Ohio UFE Factor, and 3) [1-Deration Factor]

Answer: The product of ‘Hourly Load’ & ‘AES Ohio UFE Factor’ is Load With Losses.  Multiplying that by ‘Deration Factor’ results in Marginal (Transmission) Losses.  To obtain Load Without Losses, subtract Marginal Losses from the product of ‘Hourly Load’ and ‘AES Ohio UFE Factor’.
