§53731 Commercial Demonstration Ocean Thermal Energy Conversion Facilities and Plantships

Summary

Lets the Administrator guarantee loans or make a promise to guarantee loans that pay to build, rebuild, or fix commercial demonstration ocean thermal energy conversion (OTEC) facilities or plantships, and can cover past costs the borrower already paid. Guarantees may support no more than 5 facilities or a total of 400 megawatts, whichever comes first. The usual rules for loan guarantees in the same subchapter apply unless this law says something different. The part of a project not paid with federal appropriations must still pass the required economic-soundness check. The Secretary of Energy, after talking with the Administrator, must certify that there is enough performance and payment security to bring the federal risk down to a reasonable level. In that decision the Secretary must consider whether the technology has been shown to work at a useful scale and the need and benefits to the United States of the project. A guarantee cannot be for more than 87.5% of the actual cost (or the financed portion if federal funds also support the project). A special OTEC Demonstration Fund is set up inside the parent account to hold money for guarantees that don’t fit the normal rules. Money related to these guarantees must go into that fund while related obligations are outstanding. The fund can transfer excess assets to the parent account when its balance is larger than the guarantees and related obligations still outstanding. The parent account is not responsible for guarantees made under this authority. The total unpaid principal backed by the OTEC Fund cannot exceed $1,650,000,000. The normal rules for issuing and paying obligations apply, but those obligations can be paid only from the OTEC Fund. Interest on these guaranteed loans must be reported as taxable income.

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)

(A)amounts received by the Administrator under subchapter I of this chapter related to guarantees or commitments to guarantee made under this section shall be deposited only in the OTEC Demonstration Fund; and
(B)when obligations issued by the Administrator under section 53723 of this title related to the OTEC Demonstration Fund are outstanding, any amount received by the Administrator under subchapter I of this chapter related to ocean thermal energy conversion facilities or plantships shall be deposited in the OTEC Demonstration Fund.
(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.

In subsection (a), the words “upon such terms as he shall prescribe” are omitted as unnecessary because section 53702(a) of the revised title provides the Secretary authority to prescribe the terms. The text of 46 App. U.S.C. 1279c(a)(1) is omitted as obsolete. In subsection (f)(1), the words “account established under section 53717(b)(1) of this title” are substituted for “Federal Ship Financing Fund” because the accounts under section 53717 replace the Federal Ship Financing Fund. See the explanation for section 53717. In subsection (f)(2)(B), the word “conversion” is substituted for “conversional” to correct an apparent error.
