; (ii) how the proposed transmission facility would alleviate the electric energy transmission capacity constraints or congestion described in clause (i); (iii) the boundary of the proposed transmission facility and the rationale for that boundary; (iv) the voltage, transmission capacity, and route of the proposed transmission facility; (v) how the proposed transmission facility is expected to affect costs to consumers to purchase electricity; and (vi) any other matter that the Secretary determines necessary to carry out subparagraph (C), including by providing any data that the Secretary determines necessary to carry out that subparagraph. (C) Deadline Not later than 90 days after receiving a complete application under subparagraph (A), the Secretary, after consultation with affected States, local authorities, and Indian Tribes, shall approve the application and designate the applicable transmission facility as a national interest high-impact transmission facility if the Secretary determines that— (i) the proposed transmission facility— (I) is, or will be, in the national interest, based on the criteria otherwise applicable to a national interest electric transmission corridor under subsection (a)(4); (II) is, or will be after construction or modification, capable of transmitting electricity at a voltage of not less than 345 kilovolts; (III) (aa) adds not less than 750 megawatts of new transmission capacity within a single linear path or right-of-way; or (bb) would increase the existing transmission capacity within a single linear path or right-of-way by not less than 750 megawatts; (IV) the proposed transmission facility crosses or will cross— (aa) the exterior boundary of not fewer than 2 States; or (bb) the exterior boundary of at least 1 State and the outer Continental Shelf
