Additional 1.5 Million Megawatt-hours of Renewable Energy Could Be Generated through Hydropower at Existing Reclamation Sites


Newest report shows hydropower generation at canal sites in Colorado, Oregon, Wyoming and other western states could power more than 30,000 homes

WASHINGTON, D.C. – April 13, 2012 – (RealEstateRama) — As part of President Obama’s all-of-the-above strategy for American energy, Secretary of the Interior Ken Salazar and Assistant Secretary for Water and Science Anne Castle announced today that the department has identified 373 existing Bureau of Reclamation canals and conduits that have the combined potential of generating an additional 365,219 megawatt-hours of hydropower annually.

This finding builds upon the 191 existing Reclamation dam and reservoir sites identified in 2011 with a potential of 1.2 million MWh annually. Reclamation has now identified a potential for 1.565 million MWh of additional electricity that could be generated annually at existing Reclamation conduits.

“Hydropower is an important part of President Obama’s initiative to generate 80 percent of electricity in this country from a diverse set of clean energy sources by 2035,” Salazar said. “Identifying and developing hydropower potential at existing facilities is one way we’re putting the all-of-the-above strategy to develop American energy sources into practice.”

The new March 2012 report, Site Inventory and Hydropower Energy Assessment of Reclamation Owned Conduits, prepared by the Bureau of Reclamation, supplements a March 2011 report, Hydropower Resource Assessment at Existing Reclamation Facilities. The 2011 report estimated that additional hydropower capabilities could create enough renewable energy to annually power more than 104,000 households. The 2012 report adds the potential from canals and conduits. The 2011 and 2012 reports are available

“Developing hydropower in existing publicly owned canals gives us an additional source of consistent, sustainable and reliable energy supplies in the West, with minimal impact on other natural resources,” Castle said. “Adding power generation to these canals would provide power for up to 32,500 households. Combined with the generation potential at existing dams and reservoirs, up to 136,500 households could be served. These reports highlight the exciting potential for new, environmentally sustainable hydropower development and creation of related jobs at existing facilities throughout the western United States.”

The assessment released today on canals shows that about 70 percent of the potential capacity is located in three states: Colorado, Oregon and Wyoming, although 13 of the 17 western states have new generation potential from conduits.

This assessment provides information to Reclamation and potential private developers so they can determine whether to study these sites for development. The report includes the capacity, energy potential and proximity to distribution/transmission lines for each site. The report also provides site maps.

Development of hydropower at the identified sites would proceed along one of Reclamation’s normal hydropower development processes—either through Reclamation’s Lease of Power Privilege process or the Federal Energy Regulatory Commission’s licensing process, depending on which entity has jurisdiction over a particular project.

If a project is developed under Reclamation’s Lease of Power Privilege process, the project may be eligible to proceed through an existing Categorical Exclusion from NEPA requirements which should save the developer time and money. Reclamation recently issued a temporary directive and standard for its Lease of Power Privilege requirements and process. It is also available for public review and comment at

The Bureau of Reclamation manages more than 47,000 miles of canals, laterals, drains, pipelines and tunnels. Sites included in this supplemental report as having potential for hydropower development have a drop of at least five feet, operate for at least four months of the year, and have a generation potential of at least 50 kW based upon flow rate of canal and the drop height. Not all of Reclamation’s canals meet these criteria.

Both the 2011 and 2012 reports support the 2010 Memorandum of Understanding among the Department of the Interior, the Department of Energy, and the Army Corps of Engineers that enhances the coordination of their efforts to provide the nation with affordable, reliable and environmentally sustainable hydropower.
