Question: Will DTE be incorporating the directives from the MI PSC Study of Long-Duration and Multi- Day Energy Storage published on February 27, 2025 into their procurement plans within this RFP? In light of the MI PSC Study of Long-Duration and Multi-Day Energy Storage, will DTE consider evaluating LDES and MDS differently than shorter duration energy storage?
Answer: DTE acknowledges the MPSC’s Study of Long-Duration and Multi-Day Energy Storage report recommendations and will continue to ensure it aligns with industry best practices and requirements set by the MPSC. DTE intends to evaluate storage technology capabilities holistically, including ancillary benefits associated with all technology types.

Question: How are the 'total resource benefits' from energy, capacity, ancillary services calculated under the value to cost ratio methodology? is it a simple product of the price of benefit type x benefit quantity delivered? will a detailed methodology for Value to Cost Ratio provided?
Answer: The total resource value will be a function of the expected accreditation and dispatch of the generation resource; if dispatchable, the unit will be modeled based on the hourly economic dispatch expectation leveraging forward price curves for each type of market-based benefit. If a unit is an intermittent resource, the benefits will be modeled based on the expected production curve. The total resource costs are a function of the proposed and incurred costs based on a bidder’s proposal. Both the resource values and costs will be converted to NPV form. The ratio of the NPV of value to the NPV of cost would establish the comparative metric. For example, a ratio of 1.0 indicates expected benefits to exactly equal the resource’s cost over the period of study (lifetime of PPA, or ownership of asset).

Question: Does DTE have a preferred BESS duration (4-hours, 8-hours, etc)?
Answer: DTE has not established a preference for storage duration. However, please note that the duration will have an affect on the overall evaluated value of the facility to DTE. Bidders are advised to assess whether the incremental cost to DTE for higher duration may confer outweighing benefits that would be evaluated favorably per the economic evaluation. Per the Evaluation Scorecard, "all Proposals will be evaluated and compared against each other using a value to cost ratio. The value to cost ratio will compare the total resource benefits (i.e., energy, capacity, ancillary) to the total resource costs (i.e., capital, O&M, fuel, financing). Proposals with a higher value to cost ratio will be scored higher than Projects with a lower value to cost ratio."

Question: We had a question related to Section 3.7.11.1 Transmission of the All-Source RFP. It asks for "Interconnection costs paid to date and estimated future payments schedule, including network upgrades; specify reimbursable vs. non-reimbursable costs". Projects not in at least Phase II of the DPP Process will not have expected transmission upgrade costs for their project from MISO. If those costs have not been provided by MISO yet, is a statement explaining this acceptable? IF not, what additional information would be helpful to evaluate projects not at this point in the DPP process?
Answer: Please provide all requested information to the extent available. If the information is not available due to the status being less advanced (but beyond the Eligibility and Threshold Criteria), that is acceptable. Please provide a statement regarding the status and what is currently available.

Question: In the RFP documents, it says bidders must be on the waitlist for the MISO 2026 cycle if they submit an interconnection application after the MISO 2025 queue cycle. Given MISO may not allow applications for the 2026 cycle until the window opens, is there a way to prove an intent to submit a project into the MISO 2026 cycle as soon as it opens?
Answer: Submission to MISO at this time, given the cap has been exceeded, should place the project in the MISO 2026 cycle. We are requesting confirmation of this submission as part of the submitted proposal.

Question: In the RFP Document, it is specified that DTE will be the market participant for any awarded projects. However, the Proposal Pricing Form calls for "Market Participant" which is defined as "your official company name." Could you confirm which is the case? In the Proposing Pricing Form, the cell formatting rules in the "Contract Length (PPA/TA)" below prevent us from entering our desired contract term length. How should we proceed?
Answer: Please enter your company name under the field "Market Participant." Within the context of the form, we are requesting the bidder's name in this field. We recognize DTE will be the market participant for awarded projects. The Pricing form has been updated to correct the issue you noted. Thank you for letting us know.

Answer: Yes, existing thermal gas projects may bid if they propose a pathway to comply with the Clean Energy Systems definition by 2035.

Question: Hello, What is the contract term length DTE would like to see for PPA proposals? In section 2.3 of the All Source RFP Document, it states that PPAs shall have a term of no more than 20 years but have the ability to extend. However, in Exhibit N_PPA Technology Neutral document, there is a footnote on page 8 which states the minimum term permitted is 20 years.

Question: Settlement (section 3.8) – it says that the Offtake (DTE) is responsible for the settlement with MISO of all charging energy, discharging energy, and negative discharging energy delivered at the Delivery Point, including all costs associated therewith, as well as all charges associated with scheduling activities. Does this mean the project will not incur any QSE costs during the term of the Toll? As in DTE is the QSE?
Answer: Yes, as DTE is the responsible entity for settlement, the project would not be the QSE and therefore not incur costs. DTE is the QSE.

Question: We recently participated DTE’s BESS-only RFP and, as part of that process, reviewed and commented on the proforma agreements included in the BESS-only RFP materials: a DTE proforma tolling agreement dated May 9, 2025 (the “May 9th DTE Proforma TA”), and a DTE proforma build-transfer agreement dated May 9, 2025 (the “May 9th DTE Proforma BTA”). We are now also preparing to submit energy storage proposals in DTE’s all-source RFP and, as part of this process, are reviewing the relevant proforma agreements: a DTE proforma tolling agreement dated March 31, 2025 (the “March 31st DTE Proforma TA”) and a DTE proforma build-transfer agreement dated March 31, 2025 (the “March 31st DTE Proforma BTA”). It appears that the March 31st DTE Proforma TA is the same document as the May 9th DTE Proforma TA, except that the March 31st DTE Proforma TA omits certain updates and clean-up corrections that were later made to the May 9th DTE Proforma TA. Likewise, it appears that the March 31st DTE Proforma BTA is the same document as the May 9th DTE Proforma BTA, except that the March 31st DTE Proforma BTA omits certain updates and clean-up corrections that were later made to the May 9th DTE Proforma BTA. In light of this, we are concerned that we are currently reviewing outdated versions of DTE’s proforma agreements. Please confirm whether, as part of this all-source RFP, bidders should be reviewing and commenting on the March 31st DTE Proforma TA or the May 9th DTE Proforma TA, and whether they should be reviewing and commenting on the March 31st DTE Proforma BTA or the May 9th DTE Proforma BTA.
Answer: Please review and comment on the March 31 version. If you wish to include revisions from the May 9 pro-forma, you may include them as part of your redlines to the agreement.
