Potential for additional hydropower in Arizona

Arizona rivers have the potential to host 4 hydroelectric power plants of more than 1 MW capacity each at existing dams, plus one on the Colorado River, according to a study by Oak Ridge National Laboratory for the US Dept. of Energy.  

Overall, the report concludes that nationwide "Hydropower generation could increase by 12 GW, or about 15% of current capacity, without building one dam on the nation’s waterways."
