Legislation Expands U.S. Hydropower Production Which Will Benefit Pumped Storage and Solar Dispatchability

Legislation designed to expand hydropower production in the United States by improving and streamlining the licensing process for small hydropower projects is now law. “President Obama’s signature on hydropower legislation is terrific news for expanding renewable energy and creating jobs across the country,” said Voith Hydro President and CEO Kevin Frank.
The Hydropower Regulatory Efficiency Act will require FERC to examine a 2-year licensing process for non-powered dams and closed loop pump storage. TVA should give top priority to increasing their pumped storage using no longer active mine, coal washing stations and converting them to closed pumped storage facilities. First, these are environmentally damaged facilities that need attention. Second, by adding a surface reservoir to receive the water from the elevated tailing ponds, TVA could increase its pumped storage first with closed pumped storage, then modifying existing dams to create a lower pond below the dam receiving stream. According to one source at TVA the issue with increasing pumped storage is the objection on environmental grounds. The answer is to select those sites that would have the lowest environmental impact using groups like the Sierra Club to help with the selection and the environmental impact study.

We need to increase pumped storage for both renewables and for nuclear plants. TVA has 47 dams listed on their website. There is a good chance that some of these dams would lend themselves to pumped storage. That is where TVA should invest.
