Table 9 - Power Marketing Administration
(Updated October 6, 2023)
The Department of Energy Order No. RA6120.2 paragraph 11 (b) reads as follows:
"For purposes of this paragraph, the yield rate is the average yield during the preceding fiscal year on interest-bearing Treasury marketable securities of the United States which, at the time the computation is made, have terms of 15 years or more remaining to maturity. The average yield shall be computed as the average during the fiscal year of the daily bid prices. Where the average, so computed, is not a multiple of one-eighth of one percent, the yield rate shall be the multiple of one-eighth of one percent nearest to such average yield."
The interest rate determined for fiscal year 2024 in accordance with the above-quoted formula is 4.0332% which adjusted to the nearest 1/8 of 1% is 4%.
Section 9 of Public Law 86-529 specifies that the interest rate for the Colorado River Storage Project and its participating projects "shall be determined by the Secretary of the Treasury, as of the beginning of the fiscal year in which construction is initiated, on the basis of the computed average interest rate payable by the Treasury upon its outstanding marketable public obligations, which are neither due nor callable for redemption for fifteen years from the date of issue."
The interest rate determined in accordance with the above-quoted formula is 3.051%.
