As stated in Section III.F. Questions Regarding Eligibility (page 31) of the Funding Opportunity Announcement (FOA), “DOE will not make eligibility determinations for potential Applicants prior to the date on which applications to this FOA must be submitted. The decision of whether to submit an application in response to this FOA lies solely with the Applicant.”
However, for your purposes in making that decision, we offer the following based on the limited information provided in your question:
The FOA does not preclude multiple installations in two geographically distinct locations, provided both proposed sites meet the requirements of the Topic Area and the Applicant and application meet the eligibility requirements published in the FOA.
Per Section I.B.2. of the FOA, applications being sought under Topic Area 2 are for the deployment of “(1) community-scale clean energy generating system(s) (Subtopic Area 2.a.) or (2) community-scale energy storage on Tribal Lands (Subtopic Area 2.b.).” [Emphasis added]
More specifically, per Section I.B. (page 10) “Applications exclusively proposing clean energy generating system(s) will only be accepted under Subtopic Area 1.a. and Subtopic Area 2.a. Applications exclusively proposing energy efficiency measure(s) will only be accepted under Subtopic Area 1.b. Applications proposing a combination of clean energy generating system(s) and energy efficiency measure(s) will only be accepted under Subtopic Area 1.c. Applications exclusively proposing energy storage will only be considered under Subtopic Area 2.b. and applications proposing integrated energy system(s) will only be considered under Topic Area 3 and Subtopic Area 4.a. Projects proposing energy infrastructure will only be accepted under Subtopic Area 4.b” [Emphasis added] See Appendix A for the definition of Integrated Energy System(s).
Therefore, as described in your question, the ‘battery/renewable energy generating systems’ does not appear to meet the requirements of Topic Area 2; however, the proposed project may be consistent with the types of projects being sought under Topic area 3 (Integrated Energy System(s) for Autonomous Operation).
Per Section I.B.2. (page 18), “For the purposes of Topic Area 2 [Community-Scale Clean Energy Generating System(s) or Community Energy Storage Deployment], “community-scale” means serving a “substantial” number of the total buildings within a community, or a “substantial” portion of the community’s energy load, or an entire tribal community. For the purposes of this FOA, “substantial” means of “ample or considerable amount”.” [Emphasis added] Per Section I.B.3.b. (page 22), “Under Subtopic Area 3.b. [Tribal Community Resilience], the DOE Office of Indian Energy is soliciting applications to install community-scale integrated energy system(s) for autonomous operation (independent of the traditional centralized electric power grid) to power a “substantial” number of Essential Tribal Buildings within a community, or a “substantial” portion of the community’s energy load, or an entire tribal community for community resilience, where for the purposes of this FOA, “substantial” means of “ample or considerable amount”.” [Emphasis added]
As defined under Appendix A, ““Community” for the purposes of this FOA, means a group of any size whose members reside in a specific locality, share government, and often have a common cultural and historical heritage.” [Emphasis added]
Therefore, based on the FOA definition of “community”, ‘two geographically separate tribal communities’ would not be considered a single community, unless the members of both tribal communities reside in a specific locality, share a government, and may have common cultural and historic heritage.
Please review the applicant eligibility requirements under Section III.A. to ensure the ‘regional tribal organization’ meets the eligible requirements of being: “(1) an Indian Tribe; (2) Intertribal Organization; or (3) Tribal Energy Development Organization; and (4) on whose Tribal Lands the project(s) will be located”, as those terms are defined in the FOA.
