This section may be used to guarantee obligations for a total of not more than 5 separate facilities and plantships or a demonstrated 400 megawatt capacity, whichever comes first. (b) Applicability of Other Provisions .— Except as otherwise provided in this section, a guarantee or commitment to guarantee under this section is subject to all the provisions applicable to a guarantee or commitment to guarantee under subchapter I of this chapter. (c) Economic Soundness .— The required determination of economic soundness under section 53708 of this title applies to a guarantee or commitment to guarantee for that portion of a facility or plantship not to be supported with appropriated Federal funds. (d) Reasonableness of Risk .— A guarantee or commitment to guarantee may not be made under this section unless the Secretary of Energy, in consultation with the Administrator, certifies to the Administrator that, for the facility or plantship for which the guarantee or commitment to guarantee is sought, there is sufficient guarantee of performance and payment to lower the risk to the United States Government to a reasonable level. In deciding whether to issue such a certification, the Secretary of Energy shall consider— (1) the successful demonstration of the technology to be used in the facility at a scale sufficient to establish the likelihood of technical and economic viability in the proposed market; and (2) the need of the United States to develop new and renewable sources of energy and the benefits to be realized from the construction and successful operation of the facility or plantship. (e) Amount of Obligation .— The total principal amount of an obligation guaranteed under this section may not exceed 87.5 percent of— (1) the actual cost or depreciated actual cost of the facility or plantship; or (2) if the facility or plantship is supported with appropriated Federal funds, the total principal amount of that portion of the actual cost or depreciated actual cost for which the obligor is obligated to secure financing under the agreement between the obligor and the Department of Energy or other Federal agency.

(3) Transfers .— Assets in the OTEC Demonstration Fund may be transferred to the parent account when and to the extent the balance in the OTEC Demonstration Fund exceeds the total guarantees or commitments to guarantee made under this section then outstanding, plus obligations issued by the Administrator under section 53723 of this title related to the OTEC Demonstration Fund. (4) Liability .— The parent account is not liable for a guarantee or commitment to guarantee made under this section. (5) Maximum unpaid principal amount .— The total unpaid principal amount of the obligations guaranteed with the backing of the OTEC Demonstration Fund and outstanding at any one time may not exceed $1,650,000,000. (g) Issuance and Payment of Obligations .— Section 53723 of this title applies to the OTEC Demonstration Fund.
