Question: According to footnote #4 within the Form APA (page 3), the Investment Tax Credit language will not apply to APA proposals. Given that, can Duke confirm that the ITC % and Safe harboring Strategy (rows 351 and 352 of the Solar Utility Ownership response form) do not need to be filled out for Asset Transfer proposals.
Answer: Asset Transfer proposals should clarify whether they are proposing to ITC qualify the proposed project or not. If Duke will have ITC qualification responsibility, the evaluation/utility ownership team will determine the appropriate ITC qualification year based on the details of the project/transaction and the target in service date. As noted, all projects placed in service after 12/31/25 will qualify for the 10% ITC.

Question: It seems like Appendix K for Asset Purchase Agreements came with a couple exhibits. What is required of these exhibits? Should be a redline, an issues list, a list of exceptions, or some other type of deliverable?
Also beyond the attachment checklist, is there anything else required for APA?
Answer: Selected Asset Transfer proposals and Asset Transfer plus EPC proposals will first execute the LOI/Term Sheet, followed by the full APA. MPs are encouraged to provide any redline to the LOI/Term Sheet with the proposal submittal. The attachment checklist is meant to help MPs ensure the major requirements are included, but there may be additional documents beyond the checklist that the MP would provide for completeness. Submitting your Proposal early can give the IE extra time to review it and make sure there are no required elements missing.

Question: Can you please confirm the below statement from the Bid Input form? Is there a particular document that we should be referencing? Thanks in advance.
*Bidder is Expected to Select a Reasonable "Backfeed to GSU" Based on Provided Transmission Provider's Guidance on Schedule Requirements.
Answer: This comment is simply meant to reiterate that bidders should make reasonable assumptions regarding the transmission provider’s guidance on when backfeed is realistically going to be available, for example, it would be unrealistic to assume backfeed would be available in 2024 for projects participating in 2022 DISIS.

Question: The RFP document and LOI (included below) state that security posted by the MP to the transmission provider will be released/cancelled while the APA states that all deposits (including Interconnection Deposits) and security will be transferred to the Buyer but says nothing about those amounts being subsequently released back to Seller or cancelled. For the Purchase Price (under an APA) that is input into the RFP spreadsheet, should we include or exclude the expected deposits/security under the Interconnection Agreement? If deposits/security will be released to the Seller, can you confirm whether this includes/excludes the study deposits and M1-4 Security?
RFP Document 6/20/2022
B. UTILITY OWNERSHIP PROPOSAL PRICING. All Asset Acquisition Proposal pricing shall be inclusive of all interconnection study costs (but should exclude any accounting true ups for study costs which shall remain with the MP) and costs of executing and maintaining the Interconnection Agreement until the agreement is assigned to DEC/DEP at definitive agreement closing. All Utility Ownership Track Proposals are required to ultimately have a federal jurisdictional interconnection agreement. After assignment of the Interconnection Agreement to DEC/DEP, MP shall have no continuing obligations under the Interconnection Agreement and DEC/DEP shall work directly with the Transmission Provider to cause the release or cancellation of security previously provided by MP under the original Interconnection Agreement.
Letter of Intent – Exhibit A-2
5. Interconnection. The Parties intend that the Project will interconnect at the [?] and the Purchase Price is inclusive of all interconnection study costs (but excluding any study deposits) and costs of executing and maintaining the Interconnection Agreement (“IA”) until the agreement is assigned to Buyer at Closing. For projects that submitted and were studied as subject to state jurisdictional interconnection requirements and procedures (“State Jurisdictional”), following the completion of the study process the Seller will execute a State Jurisdictional IA, prior to Closing the Seller will terminate the State Jurisdictional IA and execute an IA subject to federal jurisdictional interconnection requirements and procedures (“FERC Jurisdictional LGIA”), the FERC Jurisdictional LGIA will then be assigned to Buyer at Closing. For projects that submitted and were studied as FERC Jurisdictional, following the completion of the study process the Seller will execute a FERC Jurisdictional LGIA, which will be assigned to Buyer at Closing. After the FERC Jurisdictional LGIA has been assigned to Buyer, Seller shall have no continuing obligations under the FERC Jurisdictional LGIA and Buyer shall work directly with the Transmission Provider to cause the release or cancellation of security previously provided by Seller under the original interconnection agreement. Seller shall also be responsible for resolution of any identified third-party affected system impacts, including any additional required studies, scopes of work and/or upgrades, for such affected, or potentially affected, third-party systems.
Asset Purchase Agreement
2.1 Purchase and Sale of Project Assets
(a) Other than the Excluded Assets, on the terms and subject to the conditions of this Agreement, effective as of the Closing, Seller will sell, assign, transfer, convey, and deliver to Buyer, and Buyer will purchase and acquire from Seller, free and clear of any and all Liens, other than Permitted Liens, all of Seller’s right, title and interest in and to all of the assets, properties and rights of every kind and nature, whether real, personal or mixed, tangible or intangible (including goodwill), wherever located and whether now existing or hereafter acquired, which relate to, or are used or held for use in connection with, the Project (collectively, the “Project Assets”), including, without limitation, all of Seller’s right, title and interest in and to the following:
(6) all deposits (including the Interconnection Deposits), security, advances, pre-paid expenses, credits, accounts receivable, notes receivable, and other receivables (including any such item relating to the payment of Taxes), relating to the Project, the Project Assets or the Assumed Liabilities, including, without limitation, those listed on Schedule 2.1(a)(vi);
Answer: For the Purchase Price (under an APA) that is input into the RFP spreadsheet, it is the Buyer’s intention that the Purchase Price factors in the Seller’s costs of providing any such deposits/securities under the IA, such as the carrying cost of a cash deposit or a letter of credit, but not the actual security itself that will be released back to Seller. As an example, if the IA required a $1M deposit, the Purchase Price should not include the $1M deposit, because said deposit will be returned to the Seller after closing by the Transmission Provider. Regarding study deposits, the Seller will reconcile their allocated costs with the Transmission Provider directly and any refund or additional payments will be handled directly with the Transmission Provider.

Question: The RFP asks the bidder to provide an Interconnection Facilities Cost Estimate. To properly respond to this question, I am assuming most bidders will refer to the DEC/DEP Standard Interconnection Cost Estimates document provided in the RFP Documents. In reviewing Figure 1 of that document, the differentiation of cost responsibilities illustrated in red vs green make it unclear who is responsible for the cost of Tap / POI Switching Equipment in DEC. Those costs are listed under "Network Upgrades" which in our understanding, would be the responsibility of the utility provider. However, the depiction in Figure 1 make it look like some of that equipment is colored red (being a project owner responsibility however the vague labels make deciphering the diagram a challenge). For DEC interconnections, assuming a standard tap of 225', who bears the cost of the Tap / POI Switching Equipment? Is the responsbility for that equipment the same for DEP interconnections as well?
Answer: The Standard Interconnection Costs document is meant to provide guidance on estimating cost and was written for a “standard” Inverter Based Resource interconnection, which is a single breaker tap (though of course, some facilities require a different solution). Tap and tap line are two distinct things, and the question may be using the terms interchangeably. The Transmission Provider’s Interconnection Facilities (“TPIF”) consists of the tap line (1.1) and the interconnection station (1.2)—this is shown in red. The tap or POI switching equipment (2) is a Network Upgrade (“NU”)—this is shown in green. The tap line is a TPIF and the bidder’s responsibility. The tap is a NU and the Transmission Provider’s responsibility. Regardless of how long the tap line is, the tap / POI switching equipment is a NU. To respond to this question, the bidder should reference the cost from the table on page 1 in the Standard Interconnection Costs document. For example, the TPIF for a typical DEC 100 kV interconnection has a TPIF cost estimate of $4,100,000.
