Southwestern Power Administration Fund Establishment Act

This bill establishes the Southwestern Power Administration Fund within the U.S. Treasury to consolidate existing financial accounts. It directly affects the Southwestern Power Administration (a federal power marketing agency) and the Department of Energy, by merging unexpended balances from three previous funds into one centralized account. The fund will be used exclusively for operating power transmission facilities, marketing electricity, building infrastructure, and related administrative costs under existing laws. The bill streamlines financial management without creating new programs or altering policy.
