Reports and Data
The Replacements Book identifies critical water resource and power system units of property and associated service lives based on empirical data and subject matter expert input. Historically published by Reclamation and the Western Area Power Administration (WAPA), the two agencies have used the Replacements Book to inform the planning, budgeting, and repayment of power system maintenance, replacement, and refurbishment activities. Beginning in FY2013, Reclamation and WAPA partnered with the US Army Corps of Engineers (Corps) and the Bonneville Power Administration (Bonneville) to update the Replacements Book. The update was administered through a Steering Committee, representing agency power and finance personnel. Corps and Bonneville participation promotes more consistent financial reporting and rate setting processes across the Federal hydropower community. The updated Book was published in FY2017.
An errata was issued on October 6, 2017 to correct Intake Gates (Table Item #42, p. 4-49) service life. The assigned 100 year service life was a typo. Intake Gates service life has been corrected to read 50 years, per Justification Number 29 (p. App-47). The correction - as well as updated agency logos - is reflected in 2017 REVISION 1.1.

Hydropower - A Key to Prosperity in the Growing World (Produced in Cooperation with the International Energy Agency)
Hydropower Memorandum of Understanding (MOU)
To promote reliable, affordable, and environmentally sustainable hydropower, the U.S. Department of the Interior (through Reclamation), the U.S. Department of Energy (through the Office of Energy Efficiency and Renewable Energy), and the Department of Army (through the U.S. Army Corps of Engineers) entered into a Memorandum of Understanding for Hydropower (MOU), signed on March 24, 2010. The MOU provides for a long-term, collaborative working relationship, prioritizing similar goals and aligning ongoing and future renewable energy development efforts between the three agencies. In April 2012, the agencies published a two-year progress report to document MOU achievements.
To build upon the successes accomplished through this inter-agency partnership, the agencies renewed their MOU commitment on March 24, 2015 with a second phase of collaboration outlined in a Phase II Action Plan. The Action Plan details a second phase of collaboration, which seeks to support the Administration’s goals for doubling renewable energy generation by 2020 and improving federal permitting processes for clean energy as established in the President’s Climate Action Plan. Through continued collaboration and partnerships with other federal agencies, the hydropower industry, the research community, and numerous stakeholders, the agencies intend to continue working toward the objectives and goals of the MOU.
Bureau of Reclamation Sustainable Energy Strategy (FY2013 - FY2017)
A new sustainable energy strategic plan released on November 14, 2013 will help guide the Bureau of Reclamation into the future as the agency continues its vital role in developing and supporting renewable energy production for the nation's power grid.
Six long-term strategic objectives to further Reclamation's sustainable energy mission were developed to help guide Reclamation in this important endeavor:
- Increase renewable generation from Reclamation projects.
- Facilitate non-federal development of renewable energy projects.
- Increase energy savings and conservation at Reclamation projects.
- Support integration of variable non-dispatchable renewable resources in the United States electrical grid.
- Increase benefits of renewable energy through technological innovation.
- Improve management efficiencies related to the implementation of renewable energy and energy savings projects.
Hydropower Resource AssessmentsPotential Hydroelectric Development at Existing Federal Facilities for Section 1834 of the Energy Policy Act of 2005 (May 2007)
This report complies with Section 1834 of the Energy Policy Act of 2005 (Section 1834) that requires the Secretary of the Interior, the Secretary of the Army, and the Secretary of Energy to “jointly conduct a study assessing the potential for increasing electric power production at federally owned or operated water regulation, storage, and conveyance facilities.” The study participants included select staff of the Bureau of Reclamation, the U.S. Army Corps of Engineers, the Bureau of Land Management, the Bureau of Indian Affairs, the National Park Service, the U.S. Fish and Wildlife Service, the Western Area Power Administration, the Southeastern Power Administration, the Southwestern Power Administration, and the Bonneville Power Administration.
The study examined 871 existing federal facilities, with and without hydroelectric generating capability, assessing their physical capacity for generation or generation expansion and their economic viability based on comparisons with regional electric power rates. The report does not include any assessments of lands not under federal domain or consider new dam construction. In addition, the study participants developed and included assessment tools for generating capacity and economic viability that may be used and updated for future use.
The 1834 Report contains no recommendations. Rather, the report only attempts to give a broad inventory and assessment of future hydropower development at federal facilities under the jurisdiction of the participating agencies. The report is in pdf format. Additional analysis tools are included below.
As a component of the MOU for Hydropower, and recognizing the current national emphasis on renewable energy and its extensive existing water infrastructure systems, Reclamation has produced the Hydropower Resource Assessment at Existing Reclamation Facilities (Resource Assessment) to assess hydropower development at existing facilities to contribute to nationwide renewable energy strategies. This report provides a reconnaissance level assessment of the hydropower potential at 530 sites throughout Reclamation including dams, diversion dams, and some canals and tunnels. All 530 sites were considered in the analysis, of which, 191 sites were determined to have some level of hydropower potential. 70 of those sites, with a total of 225 MW of generation capacity, also show some economic potential for hydropower development. Despite its preliminary level of analysis, the Resource Assessment provides valuable information on hydropower potential at existing Reclamation facilities.
The "Site Inventory and Hydropower Energy Assessment of Reclamation Owned Conduits" report builds off of the Hydropower Resource Assessment published in March 2011. This new report identifies potential hydropower sites on Reclamation owned conduits and determines those sites’ capacity and energy potential. In addition, this study identifies proximity to distribution or transmission lines, and provides site maps for the identified sites.
The report identifies 103,628 kW of potential capacity, and 365,218,846 kWh of potential annual generation on 373 Reclamation conduit sites located in 13 western states.
A number of Resource Assessment sites have been developed by non-federal entities and currently in operation, with many more sites in some stage of active development. The file linked above identifies those Resource Assessment sites currently available for development.
This report assesses potential capacity and efficiency gains at existing, Reclamation-owned hydroelectric power facilities. Assessments were performed at the planning-level (reconnaissance-level) for purposes of screening between plants. Additional more detailed feasibility-level studies of individual plants would be needed to make final investment decisions at those specific plants that show promise for capacity additions in this study.
Inventory of Reclamation Water Surface Storage Studies with Hydropower Components
Report to Congress Implementing Provisions of Section 1840 of the Energy Policy Act of 2005 (Public Law 109-58) . This report complies with Section 1840 of the Energy Policy Act of 2005 requiring the Secretary of the Interior, acting through the Bureau of Reclamation, to develop a report "identifying and describing the status of potential hydropower facilities included in water surface storage studies undertaken by the Secretary for projects that have not been completed or authorized for construction" since 1939.
This report contains no recommendations. However, it does serve as a useful reference tool for understanding the magnitude and scope of historical study activities in specific locations. The report is in .pdf format.
