Clean Electricity Potential at Existing Dam Facilities

Adding hydropower capacity to existing dams and canals has the potential to generate up to one million megawatt hours of electricity annually.

    Installing hydropower capacity on 70 existing dams and canals could generate enough electricty to power 85,000 homes annually, as reported by the U.S. Department of the Interior.

The U.S. Department of the Interior (DOI) released on March 31 the results of an internal study that shows it could generate up to one million megawatt hours of electricity annually and create jobs by adding hydropower capacity at 70 of its existing dams, canals, tunnels and other water-handling facilities. The report, "Hydropower Resource Assessment at Existing Reclamation Facilities," estimates that the additional hydropower capabilities could generate enough clean, renewable energy to annually power more than 85,000 households, while also creating an estimated 1,200 jobs. The Bureau of Reclamation developed the report as part of President Obama's initiative to develop a comprehensive renewable energy portfolio and to meet 80 percent percent of U.S. energy needs with clean sources by 2035.

The report studied 530 sites throughout Reclamation's jurisdiction — including dams, diversion structures, and some canals and tunnels. Of those sites, the assessment made a preliminary identification of 70 facilities with the most potential to add hydropower. These 70 facilities are located in 14 states. Colorado, Utah, Montana, Texas and Arizona have the facilities with the most hydropower potential, but facilities with hydropower potential were also found in California, Idaho, Nebraska, Nevada, New Mexico, Oregon, South Dakota, Washington and Wyoming.

For many of these sites, hydropower development would be conducted under a "Lease of Power Privilege Agreement," through which a non-federal entity is given a contractual right for up to 40 years to use a Reclamation facility for electric power generation. The bureau will be publishing two Federal Register notices in the near future regarding Lease of Power Privilege opportunities at Granby and Pueblo dams in Colorado. These dams were identified in the report as having high potential for hydropower development. The report dovetails the 2010 Federal Memorandum of Understanding (MOU) for Hydropower between DOE, DOI, and the U.S. Army Corps of Engineers.

Also in hydro news, the Federal Energy Regulatory Commission (FERC) and the U.S. Army Corps of Engineers (USACE) signed an updated agreement on March 30 to coordinate their efforts evaluating proposals to construct and operate non-federal hydropower projects at USACE-owned facilities. The MOU establishes a framework for early coordination and participation between FERC and USACE to ensure timely review of proposed non-federal hydropower development applications.

Another possibility would be the lock and dam systems on the Mississippi River. I don't know how much electrcity would be produced, but I think it would provide electricity for many of the towns and cities along its route.
