Question: Does the transmission interconnect have to be on a line that is owned by Duke, or can it be on a line that is in the subject service area, such as a Centerpoint line?

Answer: There is no requirement that projects be in DEI’s system. Projects other than wind must be located in MISO LRZ6. Projects must also be transmission level projects. Projects can interconnect anywhere on the MISO transmission system within LRZ6.

Question: Are there any affiliate restrictions associated with this RFP? For example, in Duke Energy Carolinas, there are restrictions on project ownership %’s and caps on affiliate offer sizes.

Answer: There are no affiliate-specific restrictions that apply to affiliate bids or self builds. DEI and affiliates of DEI can submit projects into the process so long as the projects meet the basic requirements for participation. All bids including self builds and affiliate bids will be evaluated using the same evaluation criteria being applied to all projects submitted into the RFP. DEI and affiliates will be afforded no special advantages or special restrictions in the process.

Question: Is Duke looking to self-build assets instead/in addition to this RFP? If submissions are not favorable would they look to self-build and not accept bids?

Answer: Duke is considering self-build options and those projects will be evaluated as part of the RFP process using the same evaluation criterial that applies to all process bids.

Question: Will you give preference to projects that have more advanced MISO queue positions and thus have less uncertainty on their MISO and Affected System upgrade costs? For example, 2019 DPP queues will be past Phase 2 while 2020 will (maybe?) be past Phase 1. Would these proposal be weighted equally or would the DPP 2020 project be penalized for uncertainty of upgrade costs?

Answer: Projects will be evaluated consistent with the evaluation criteria posted to the Information Website. The Development Risk scoring category outlines how points will be awarded for projects based on their development stage.

Question: Is there a target %, minimum, or maximum capacity of the total non-intermittent supply that DEI would like to be met by BESS projects? Could that number be as low as 0% or as high as 100% of the ~1200 MW total?

Answer: There is no technology-specific target or carve out within the intermittent or non-intermittent RFPs. The RFP documents include tentative targets for each broad category. However, as noted in the solicitation documents, DEI reserves the right to deviate from those targets based on the bids received. DEI may contract with greater or fewer MW for each category than what is identified in Table 1 of the Solicitation documents.

Question: For a solar facility paired with storage, can you submit the solar + storage as an intermittent resource and then the storage as standalone as a non-intermittent resource?

Answer: DEI would encourage bidders to submit all bids and options.  For the specific scenario described, CRA would requesst that the bidders identify if bid submissions are mutually exclusive or not.

Question: Is nuclear considered for a resource for the non-intermittent RFP?

Answer: DEI would consider all options that meet the state resource location requirement for the RFP. Since it is an all-source RFP, DEI will consider a wide range of resources options however, bids for standalone coal assets will not be accepted.

Question: The non-intermittent RFP mentions hydrogen burning capabilities and is that something that needs to be in place now or a potential component in the future?

Answer: DEI is open to hydrogen bids but bids should be far enough in planning and development to be transaction ready projects.  This means bidders need to have specific details about the project's development and the anticipated costs.  Bids would need this level of detail to be evaluated against more traditional resources.

Question: For development projects is there a preference for selling projects that are at some stage of development or at NTP or at COD?

Answer: We contemplate that we’d acquire projects at one of two points, depending on the bid structure chosen.  Under an APA approach, we would acquire the project upon completion of specified conditions precedent related to the development of the project, effectively to get the project ready to start construction (NTP, as referenced in the question).  Under at BTA approach, we would acquire the project when the facility is mechanically complete (as defined under the agreement), but has not been energized or placed in service.

Question: As MISO study results are still pending for some Study Groups, will participants have the opportunity to adjust the submitted price based on the outcome of the study (network upgrade costs)?

Answer: Bidders are expected to submit a firm price for their projects.  If a project receives MISO study result information that materially impacts the project cost, DEI will consider changes in network upgrade costs on a case by case basis.

Question: Would Duke Energy Indiana consider solar projects that are not at 100% NRIS?

Answer: DEI’s RFP is intended to solicit bids to meet its future capacity needs which is dependent upon NRIS qualification.  While NRIS interconnected capacity is essential to meet those needs, ERIS interconnected capacity located in the DEI balancing area could meet those needs as well.  Therefore, DEI is accepting bids for NRIS and ERIS interconnected resources and combinations thereof . The intermittent and non-intermittent solicitation documents requests that each "Respondent shall also detail its MISO generator interconnection queue position, if any, and the types and amounts of transmission service requested (e.g. 50 MW of NRIS and/or 25 MW of Energy Resource Interconnection Service (“ERIS”))."  The value of NRIS, ERIS, or combinations and the resource’s location will be used in the evaluation process to determine the relative value of each proposal to DEI.

Question: Does Duke have a preference of solar resource datasets used for generation production estimates for BTAs?

Answer: The Duke Energy Indiana  (DEI) RFP does not require the use of a specific solar resource dataset (TMY - typical meterological year) to be used for generation production estimates,   DEI  would recommend the use of any major, acceptable datasets commonly used in the solar development industry consisting of a sufficient representative historical time period such as 20 years to provide the best estimate of future anticpated solar production.

Question: Does a facility need only to qualify for capacity accreditation in its LRZ (Zone 7), and DEI wears the responsibility to designate the project as a DNR (Designated Network Resource) for LRZ 6?

Answer: Through this RFP DEI is seeking to secure LRZ6 capacity resources.  Aside from wind resources, DEI will not accept MISO zonal risk associated with a resource.
