	Introduction

The federal government, through the Department of Energy, operates four regional power marketing administrations (PMAs), created by statute: the Bonneville Power Administration (BPA), the Southeastern Power Administration (SEPA), the Southwestern Power Administration (SWPA), and the Western Area Power Administration (WAPA). Congressional interest in the PMAs has included diverse issues such as rate setting, cost and compliance associated with the Endangered Species Act (ESA; P.L. 93-205 ; 16 U.S.C. §§1531 et seq. ), and questions of privatization of these federal agencies. In general, the PMAs came into being because of the government's need to dispose of electric power produced by federal dams constructed largely for irrigation, flood control, or other purposes, and to achieve small community and farm electrification—that is, providing service to customers whom it would not have been profitable for a private utility to serve. With minor exceptions, these agencies market the electric power produced by federal dams constructed, owned, and operated by the Corps of Engineers (Corps) and the U.S. Bureau of Reclamation (BOR). PMAs must give preference to public utility districts and cooperatives (e.g., "preference customers"), selling their power at cost-based rates set at the lowest possible rate consistent with sound business principles. The Federal Energy Regulatory Commission (FERC) regulates PMA rates to ensure that they are set high enough to repay the U.S. Treasury on schedule for the portion of federal facility costs that have been allocated to hydropower beneficiaries. Since FY2011, power revenues associated with the PMAs have been classified as discretionary offsetting receipts (i.e., receipts that are available for spending by the PMAs), thus the agencies are sometimes noted as having a "net-zero" spending authority. Only the capital expenses of WAPA and SWPA require appropriations from Congress. With energy and capacity markets changing in the western United States (especially with the growing need to integrate increasing amounts of variable renewable sources), and the development of the Energy Imbalance Market (EIM) in the West, BPA is considering whether to join the EIM, and how this might affect its operations and customers. Dams and Fish Endangerment

Environmental, fishing, and tribal advocates have sued the federal government over concerns that operating rules for hydropower dams on the Columbia and Snake Rivers (i.e., operations consistent with the National Marine Fisheries Service Biological Opinion) are inadequate to ensure survival of species threatened or endangered under the Endangered Species Act. In 2016, a federal judge overturned a previous management plan for the dams, finding that it would not be sufficient to protect salmon runs, and ordered a new management plan that could include removing the dams. However, in 2018, President Trump issued a Presidential Memorandum accelerating the process for a new management plan, requiring the biological opinion to be ready by 2020. In 2018, the Trump Administration proposed to sell the transmission assets owned and operated by the federal Power Marketing Administrations. The proposal suggested that "eliminating or reducing" the federal government's role in owning and operating transmission assets and increasing the private sector role would "encourage a more efficient allocation of economic resources and mitigate unnecessary risk to taxpayers." The Federal entities that would result after such sales could contract with other utilities to provide transmission service for the delivery of Federal power just as the Southeastern Power Administration, which does not own transmission lines, already does. Under Section 208 of the Urgent Supplemental Appropriations Act, 1986 ( P.L. 99-349 ), the executive branch is prohibited from spending funds to study or draft proposals to transfer from federal control any portion of the assets of the PMAs unless specifically authorized by Congress.
The federal government, through the Department of Energy, operates four regional power marketing administrations (PMAs), created by statute: the Bonneville Power Administration (BPA), the Southeastern Power Administration (SEPA), the Southwestern Power Administration (SWPA), and the Western Area Power Administration (WAPA). Each PMA operates in a distinct geographic area. Congressional interest in the PMAs has included diverse issues such as rate setting, cost and compliance associated with the Endangered Species Act (ESA; P.L. 93-205; 16 U.S.C. §§1531 et seq.), and questions of privatization of these federal agencies.
In general, the PMAs came into being because of the government's need to dispose of electric power produced by dams constructed largely for irrigation, flood control, or other purposes, and to achieve small community and farm electrification—that is, providing service to customers whom it would not have been profitable for a private utility to serve. With minor exceptions, these agencies market the electric power produced by federal dams constructed, owned, and operated by the U.S. Army Corps of Engineers (Corps) and the Bureau of Reclamation (BOR). By statute, PMAs must give preference to public utility districts and cooperatives (e.g., "preference customers"), and sell their power at cost-based rates set at the lowest possible rate consistent with sound business principles.

With energy and capacity markets changing in the western United States (especially with the growing need to integrate increasing amounts of variable renewable sources), and the development of the Energy Imbalance Market in the West, BPA and WAPA may have to adapt their plans with regard to generation needs and how transmission systems are developed.
In 2018, the Trump Administration proposed to sell the transmission assets (lines, towers, substations, and/or rights of way) owned and operated by the federal Power Marketing Administrations. The proposal suggested that "eliminating or reducing" the federal government's role in owning and operating transmission assets, and increasing the private sector's role, would "encourage a more efficient allocation of economic resources and mitigate unnecessary risk to taxpayers." The resulting PMA entities would then contract with other utilities to provide transmission services for the delivery of federal power, similar to what SEPA does currently. Reportedly, the proposed sale of PMA assets was dropped after opposition to the plan emerged from stakeholders. Under Section 208 of the Urgent Supplemental Appropriations Act, 1986 (P.L. 99-349), the executive branch is prohibited from spending funds to study or draft proposals to transfer from federal control any portion of the assets of the PMAs unless specifically authorized by Congress.
