Question: Can you detail the math employed to transform PJM Settlement-level load to Retail-level load as used in the calculation of a supplier's AEC requirement? As I understand the matter, Retail-level load can be calculated as (PJM Settlement-level load) / (1- Deration Factor) / (1+ Distribution Loss Factor + Transmission Loss Factor). Can you confirm?

Answer: Duquesne calculates the retail load using the settlement load without a deration factor applied minus the line losses and UFE.

Question: In the load data you provide, there is a "lost power" column. What lost power does that include? Transmission loss, etc?

Answer: Lost power is the difference between system load and what DLC billed to customers.

Question: If Alternative Energy Portfolio Requirements change such that there are new Tiers or Classes of Alternative Energy Credits other than Solar, Tier 1 and Tier 2, will suppliers or Duquesne be responsible for those Alternative Energy Credits?

Answer: The Supplier is responsible for any changes or modifications to the AEPS requirements. This would include any new tiers or classes of credits. As noted in Appendix E of the SMA, “If Alternative Energy Portfolio Requirements change by law or any other reason, DS Supplier shall be responsible for providing the credits at its expense in order to comply with its obligations under Full Requirements Service."

Question: Market Monitor, Given the record high ancillary clearing prices due to the various Winter Storms during the month of January, would Duquesne consider passing through market-based ancillary costs for Fixed-Price auction products as part of DSP-X proceedings. Could this consideration be also expressed for the Hourly Priced Large C&I product, where settled costs borne by suppliers for the month of January exceeded 50% of the March 2024 auction clearing price? Thank you.

Answer: The DSP-X Supplier Master Agreement, which governs the allocation of costs between utilities and suppliers for DSP-X, has already been approved by the Pennsylvania Public Utility Commission. The SMA will be the governing document for the upcoming March procurement, outlining how costs, including ancillary services, are handled. The approved SMA is available on the information site under the "Documents" section for your reference.

Question: For counterparties that need to complete KYC on Duquesne, who should they contact and will the representative engage with bidders before they have been awarded at least one tranche of supply?

Answer: Only Registered Bidders - those that successfully completed the Part 1 and Part 2 Application process - are allowed to participate in the auction. No additional KYC or “Know Your Customer” compliance checks are required prior to the award of tranches in the auction.
