Internal Control Weaknesses Identified During the Southwestern Federal Power System's Fiscal Year 2024 Combined Financial Statements Audit

The Office of Inspector General engaged the independent public accounting firm of KPMG LLP (KPMG) to conduct the fiscal year 2024 combined financial statements audit of the Southwestern Federal Power System (SWFPS), subject to our review. As part of this audit, KPMG considered SWFPS' internal controls over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances for the purpose of expressing its opinion on the financial statements but not for the purpose of expressing an opinion on the effectiveness of SWFPS' internal control.

KPMG performed the audit in accordance with generally accepted government auditing standards.

During the audit, KPMG identified certain deficiencies in SWFPS' internal control related to entity level controls, post-retirement benefits, workers' compensation, personal protective equipment, and operation and maintenance expenses that are included in the attached management letter.

The attached letter contains 5 findings and 17 recommendations that were issued to Southwestern Power Administration during The Southwestern Federal Power System's Fiscal Year 2024 Combined Financial Statements Audit. Management concurred with the findings and recommendations and had taken or planned to take corrective actions. Management's responses are included with each finding.
