Southeastern Power Administration

Rate Order No. SEPA-62

Georgia-Alabama-South Carolina System Power Rates

Order Confirming And Approving

Power Rates on an Interim Basis

Rate Order No. SEPA-62 and associated rate schedules are applicable to Southeastern Power Administration (Southeastern) power sold to existing preference customers in Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina. The rate schedules are approved on an interim basis, effective October 1, 2022, through September 30, 2027, and are subject to confirmation and approval by the Federal Energy Regulatory Commission (FERC) on a final basis.

Background

Power from the Georgia-Alabama-South Carolina Projects is presently sold under Wholesale Power Rate Schedules SOCO-1-F, SOCO-2-F, SOCO-3-F, SOCO-4-F, ALA-1-O, Duke-1-F, Duke-2-F, Duke-3-F, Duke-4-F, Santee-1-F, Santee-2-F, Santee-3-F, Santee-4-F, SCE&G-1-F, SCE&G-2-F, SCE&G-3-F, SCE&G-4-F, Pump-1-A, and Replacement-1. These rate schedules were approved by the FERC in docket number EF17-5-000 on January 25, 2018, for a period ending September 30, 2022 (162 FERC ¶ 62,059).

Public Notice and Comment

Notice of a proposed rate adjustment was published in the Federal Register March 25, 2022 (87 FR 17080). The notice advised interested parties of a proposed reduction in the capacity rates of approximately one percent (1%) and an increase of four percent (4%) for energy. The proposed increase in the revenue requirement was about two percent (2%). A public information and comment forum was held April 26, 2022, in Atlanta, Georgia. Written comments were accepted through June 23, 2022. Comments were received from two parties at the forum. Written comments were received from twelve interested parties.

Comments received from interested parties are summarized below. Southeastern's responses are also provided.

Oral Comment 1: In reviewing the public notice and the materials submitted to date, it appears that the rates as proposed are entirely consistent with Section 5 of the Flood Control Act of 1944 and the administrator has used his discretion to set the rates as low as possible consistent with sound business principles, and the Southeastern Federal Power Customers support that approach and continued diligence by the administrator. There are perhaps a couple of questions that the materials raise that we will follow up in further inquiries in terms of Corps revenue and Corps O&M projections, but at this time that's the sum and total of our comments right now.

Oral Comment 2: We would like to add that as we've most recently reviewed potential costs associated with stimulus dollars, that those stimulus dollars monies not be included in any future rate study. With that, that concludes my report.

Written Comment 1: The public notice represents that SEPA has proposed a de minimis rate increase to account increases in the costs of providing the hydropower. We appreciate the efforts of the SEPA staff to develop a rate that provides the lowest possible increase in the face of rising costs. Furthermore, we understand that the proposed rate does not include amounts for stimulus funds that Congress provided to the Corps in 2021. We support this decision and resulting rate.

Response to Oral Comments 1 and 2, and Written Comment 1: Southeastern continues to work with preference customers and the Corps to review operation and maintenance actual costs and estimates to ensure accuracy of cost assignment and projections to establish the lowest possible rates consistent with sound business principles within the meaning of Section 5 of the Flood Control Act of 1944. Southeastern will continue to monitor costs and processes to ensure only appropriate hydropower program related costs are reflected in power rates charged to customers.

Written Comment 2: SeFPC supports the proposed rate adjustment for the GA-AL-SC system of projects. SeFPC also comments on the authority of the Administrator to set the rates under Section 5 of the Flood Control Act of 1944. SeFPC further comments on the discretion SEPA enjoys in determining how to structure the recovery of prospective costs associated with the federal hydropower purpose. At heart of the SeFPC's comments is the assertion that stimulus funding provided to the US Army Corps of Engineers in IIJA and DRSA laws should only be included in SEPA rates to the extent that the expenditure is attributable to hydropower purposes, regardless of Corps cost accounting.

Response to Written Comment 2: Southeastern has a statutory duty to balance the recovery of costs of the Corps projects in a reasonable number of years while providing the lowest possible rates to preference customers consistent with sound business principles. Southeastern has received no financial documents from the Corps regarding the assignment of costs to the hydropower purpose related to the funding referenced in the comment. As Southeastern receives updated data, the Administrator will determine the appropriate costs that are subject to recovery though the rate in future actions.

Discussion

System Repayment

An examination of Southeastern's revised system power repayment study, prepared in December 2021, for the Georgia-Alabama-South Carolina System shows that with the proposed rates, all system power costs are paid within the appropriate repayment period required by existing law and DOE Order RA 6120.2. The Administrator, Southeastern Power Administration has certified that the rates are consistent with applicable law and that they are the lowest possible rates to customers consistent with sound business principles.

Legal Authority

Pursuant to Section 302(a) of the Department of Energy Organization Act (Pub. L. 95-91, 42 U.S.C. 7152(a)), the functions of the Secretary of the Interior and the Federal Power Commission under Section 5 of the Flood Control Act of 1944 (16 U.S.C. 825s), relating to Southeastern, were transferred to and vested in the Secretary of Energy. By Delegation Nos. S1-DEL-RATES-2016 and S1-DEL-RATES-1993, effective November 19, 2016, and November 4, 1993, respectively, the Secretary of Energy delegated to the Administrator, Southeastern Power Administration, the authority to develop power and transmission rates, to the Deputy Secretary of Energy the authority to confirm, approve, and place such rates into effect on an interim basis, and to FERC the authority to confirm, approve, and place into effect on a final basis or to disapprove rates developed by the Administrator under the delegation. By Delegation No. S1-DEL-S3-2022-2, effective June 13, 2022, the Secretary of Energy also delegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Under Secretary (for Infrastructure). By Redelegation No. S3-DEL-SEPA1-2022, effective June 13, 2022, the Secretary of Energy, for the Under Secretary (for Infrastructure), redelegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Administrator, Southeastern Power Administration, under which this rate is confirmed, approved, and placed into effect on an interim basis by the Administrator, Southeastern Power Administration.

Environmental Impact

Southeastern has reviewed the possible environmental impacts of the rate adjustment under consideration and has concluded that, because the adjusted rates would not significantly affect the quality of the human environment within the meaning of the National Environmental Policy Act of 1969, as amended, the proposed action is not a major Federal action for which preparation of an Environmental Impact Statement is required.

Determination Under Executive Order 12866

Southeastern has an exemption from centralized regulatory review under Executive Order 12866; accordingly, no clearance of this notice by the Office of Management and Budget is required.

Availability of Information

Information regarding these rates, including studies, and other supporting materials, is available for public review in the offices of Southeastern Power Administration, 1166 Athens Tech Road, Elberton, Georgia 30635-6711.

Order

In view of the foregoing and pursuant to the authority delegated to me by the Secretary of Energy, I hereby confirm and approve on an interim basis, effective October 1, 2022, attached Wholesale Power Rate Schedules SOCO-1-G, SOCO-2-G, SOCO-3-G, SOCO-4-G, Duke-1-G, Duke-2-G, Duke-3-G, Duke-4-G, Santee-1-G, Santee-2-G, Santee-3-G, Santee-4-G, SCE&G-1-G, SCE&G-2-G, SCE&G-3-G, SCE&G-4-G, Pump-1-A, and Replacement-1. The rate schedules shall remain in effect on an interim basis through September 30, 2027, unless such period is extended or until the FERC confirms and approves them or substitute rate schedules on a final basis.
