(a) Issuance and sale; terms and conditions; interest rate; limitation on aggregate principal amount outstanding
The Administrator is authorized to issue and sell to the Secretary of the Treasury from time to time in the name and for and on behalf of the Bonneville Power Administration bonds, notes, and other evidences of indebtedness (in this chapter collectively referred to as "bonds") to assist in financing the construction, acquisition, and replacement of the transmission system, to implement the Administrator's authority pursuant to the Pacific Northwest Electric Power Planning and Conservation Act [16 U.S.C. 839 et seq.] (including his authority to provide financial assistance for conservation measures, renewable resources, and fish and wildlife, but not including the authority to acquire under section 6 of that Act [16 U.S.C. 839d] electric power from a generating facility having a planned capability greater than 50 average megawatts), and to issue and sell bonds to refund such bonds. Such bonds shall be in such forms and denominations, bear such maturities, and be subject to such terms and conditions as may be prescribed by the Secretary of the Treasury taking into account terms and conditions prevailing in the market for similar bonds, the useful life of the facilities for which the bonds are issued, and financing practices of the utility industry. Refunding provisions may be prescribed by the Administrator. Such bonds shall bear interest at a rate determined by the Secretary of the Treasury taking into consideration the current average market yield on outstanding marketable obligations of the United States of comparable maturities, plus an amount in the judgment of the Secretary of the Treasury to provide for a rate comparable to the rates prevailing in the market for similar bonds issued by Government corporations. Beginning in fiscal year 1982, if the Administrator fails to repay by the end of any fiscal year all of the amounts projected immediately prior to such year to be repaid to the Treasury by the end of such year under the repayment criteria of the Secretary of Energy and if such failure is due to reasons other than (A) a decrease in power sale revenues due to fluctuating streamflows or (B) other reasons beyond the control of the Administrator, the Secretary of the Treasury may increase the interest rate applicable to the outstanding bonds issued by the Administrator during such fiscal year. Such increase shall be effective commencing with the fiscal year immediately following the fiscal year during which such failure occurred and shall not exceed 1 per centum for each such fiscal year during which such repayments are not in accord with such criteria. The Secretary of the Treasury shall take into account amounts that the Administrator has repaid in advance of any repayment criteria in determining whether to increase such rate. Before such rate is increased, the Secretary of the Treasury, in consultation with the Administrator and the Federal Energy Regulatory Commission, must be satisfied that the Administrator will have the ability to pay such increased rate, taking into account the Administrator's obligations. Such increase shall terminate with the fiscal year in which repayments (including repayments of the increased rate) are in accordance with the repayment criteria of the Secretary of Energy. The aggregate principal amount of any such bonds outstanding at any one time shall not exceed $1,250,000,000 prior to October 1, 1981. Such aggregate principal limitation shall be increased by an additional $1,250,000,000 after October 1, 1981, as provided in advance in annual appropriation Acts, and such increased amount shall be reserved for the purpose of providing funds for conservation and renewable resource loans and grants in a special revolving account created therefor in the Fund. The funds from such revolving account shall not be deemed State or local funds.

(b) Payment of principal, premiums, and interest from net proceeds; "net proceeds" defined
The principal of, premiums, if any, and interest on such bonds shall be payable solely from the Administrator's net proceeds as hereinafter defined. "Net proceeds" shall mean for the purposes of this section the remainder of the Administrator's gross receipts from all sources after first deducting trust funds and the costs listed in section 838i(b)(2) through (b)(7), (b)(11), and (b)(12) of this title, and shall include reserve or other funds created from such receipts.

(c) Purchase and sale by Secretary of the Treasury; public debt transactions
The Secretary of the Treasury shall purchase forthwith any bonds issued by the Administrator under this chapter and for that purpose is authorized to use as a public debt transaction the proceeds from the sale of any securities issued under chapter 31 of title 31, as now or hereafter in force, and the purposes for which securities may be issued under chapter 31 of title 31, as now or hereafter in force, are extended to include any purchases of the bonds issued by the Administrator under this chapter. The Secretary of the Treasury may, at any time, sell any of the bonds acquired by him under this chapter. All redemptions, purchases, and sales by the Secretary of the Treasury of such bonds shall be treated as public debt transactions of the United States.
