An auction for Standard Service Offer electricity supplies at Dayton Power & Light (AES Ohio) did not procure all of the originally targeted tranches, and the Public Utilities Commission of Ohio has ordered DP&L to hold an additional auction

The auction was originally seeking 12-month products for 100% of supplies (100 tranches) for the period June 1, 2022 - May 31, 2023

However, only 50 tranches were procured in the auction

A post-auction report states that, "the tranche target was reduced from 100 tranches to 50 tranches based on pre-determined criteria related to excess eligibility and the reservation price for the auction. The reduction was executed consistent with the auction rules and procedures."

The auction's bidding rules do not discuss specifics concerning what the criteria may be, but state as follows, "In some cases, the Auction Manager may reduce the tranche targets. The criteria that could lead to such a reduction will be determined prior to the auction but will not be announced to bidders. Once certain pre-specified criteria related to excess supply and related to the reservation price have been met, the discretion to reduce a product’s tranche target because of insufficient supply will be eliminated. Thus, any tranche target reduction would more likely occur in the earlier rounds of the auction. If the Auction Manager reduces the tranche target for a product, bidders will be informed of the revised tranche target. Any bidder that would otherwise have eligibility exceeding the new tranche targets will have its eligibility reduced so as not to exceed the new tranche targets."

The bidding rules also state, "If there is insufficient supply for the tranches to ensure competitive bidding, the Auction Manager will reduce the tranche target. The criteria that could lead to such a reduction will be determined prior to the auction but will not be announced to bidders."

For the 50 tranches procured, the tranche-weighted average price of winning bids from the auction was $75.13 per MWh, for the delivery period of June 1, 2022 to May 31, 2023

There were 7 winning bidders in the auction

PUCO directed DP&L to schedule an additional auction no later than 30 calendar days prior to the start of the delivery period to procure the remaining 50 tranches (50% of supply)
