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).
