Index / Hydroelectric Power (Dams and Pumped Storage)

The U.S. hydropower fleet has been providing clean, reliable power for more than a hundred years. However, no systematic documentation exists of the U.S. fleet and the trends influencing it in recent years. This first-ever Hydropower Market Report seeks to fill this gap and provide industry and policy makers with a quantitative baseline on the distribution, capabilities, and status of hydropower in the U.S.

Overall, the size of the U.S. hydropower fleet has continued to grow over the last decade as owners optimize and upgrade existing assets. Despite some retirements, U.S. hydropowe... More →

Index / Hydroelectric Power (Dams and Pumped Storage)

Dr. Conca reports that there is a lot of new hydroelectric power that could be installed in the U.S. without building a single new dam. He learned that during the All Energy Forum at the recent American Nuclear Society Meeting in Washington, D.C.

Almost 90% of the U.S. low-carbon energy sources come from hydropower-Dams (21%) and nuclear power (67%), which together avoid almost a billion tons of CO2 emissions each year. If the U.S. is to achieve any of the low-carbon goals the U.S. have set out for 2030 and beyond, hydropower must increase significantly and nuclear has to al least m... More →

Index / Hydroelectric Power (Dams and Pumped Storage)

Dams and irrigation significantly increase evapotranspiration, an effect that increases the loss of freshwater to the atmosphere, thereby reducing the water available for humans, societies and ecosystems on land, a new study at Stockholm University has found.

The study shows that dams and irrigation considerably raise the global human consumption of freshwater by increasing evapotranspiration - evaporation and plant transpiration from the Earth land and ocean surface to the atmosphere.

Previously, the global effects of local human activities such as dams had been undere... More →

Index / Hydroelectric Power (Dams and Pumped Storage)

Dr. Conca reports that the Department of Energy released a plan to expand hydropower by 50% through electrifying existing dams and emplacing pumped hydro storage at existing non-powered dams to facilitate more intermittent renewables like wind and solar onto the electric grid.

According to DOE Hydropower Vision, the United States could increase its hydropower electricity generation capacity from about 100 GW to 150 GW by 2050 by energizing existing dams (dams that presently have no ability to produce power), upgrading plants already producing power with more capacity, and constructi...

Dr. Conca reports that last week, the Department of Energy, under President Obama, released a plan to expand hydropower by 50% through electrifying existing dams and emplacing pumped hydro storage at existing non-powered dams to facilitate more intermittent renewables like wind and solar onto the electric grid.

Index / Hydroelectric Power (Dams and Pumped Storage)

Conventional hydroelectric generators account for 7% of the operating electricity generating capacity in the U.S. and about 6% to 7% of U.S. electricity generation each year. Conventional hydroelectric plants are different from pumped-storage facilities, which produce electricity from water previously pumped to an upper reservoir. Many of these generators are among the oldest power plants in the U.S. Hydropower plants account for 99% of all currently operating capacity built before 1930. Until 2014, hydroelectricity exceeded the electricity produced by all other renewable sources combined.

Index / Hydroelectric Power (Dams and Pumped Storage)

John Roach reports that utilities from Spain to China are increasingly relying on pumped storage hydroelectricity, first used in the 1890s to overcome the intermittent nature of wind and solar power. In the past decade, wind energy production has soared in Spain, rising from 6% of the electricity generation in 2004 to about 20% today. While that is certainly good news for boosters of renewables, the surge has come with the challenge of ensuring that electric power is available when customers want it, not just when the wind blows.

To provide a back-up to wind energy production, Spai... More →

Index / Hydroelectric Power (Dams and Pumped Storage)

Dr. Conca reports that recently (mid-2016), a federal judge forced discussion of a radical step to save endangered salmon: taking out four somewhat large hydroelectric dams on the Lower Snake River in Washington State. These four dams include Ice Harbor, Lower Monumental, Little Goose and Lower Granite Dams. They are fairly old dams and were not optimized for salmon survival. They were built primarily for navigation of barge and various river traffic, for low-carbon power, and to lesser degrees for flood control and irrigation.

And despite millions of dollars spent on fish passage i... More →

Dr. Conca reports that his local electric utility in Washington State just raised my base electricity price and are having to buy renewable energy credits because they are required to supply 9% of his state electricity from renewable sources next year and his state only produces 85% from renewables now.

Yes, electricity generation in Washington State is 79% hydroelectric, 8% nuclear, 6% wind, 4% coal and 3% gas. They have the most renewable energy generation and the lowest carbon footprint in America and have more than surpassed any reasonable low-carbon goal one could possibly imag... More →

Index / Hydroelectric Power (Dams and Pumped Storage)

Dr. Conca reports that developing countries are planning to dramatically expand hydroelectric power generation in their desperate need for electricity and irrigation. It is also a strategic decision to use their own resources. Second only to nuclear power in providing low-carbon, long-term reliable base load generation, hydroelectric is an excellent way to increase energy production without mortgaging your country's future to fossil fuel supplies.

Over six hundred hydroelectric dams are presently under construction and over 3,000 are planned for the near-future. Most of these sites ... More →

On the other hand, Dr. Conca also reports that as a result of a recent ruling by a federal judge, the U.S. Army Corps of Engineers (Corps), the Bureau of Reclamation (Reclamation) and the Bonneville Power Administration (BPA) are once again discussing the radical step of taking out four hydroelectric dams on the Lower Snake River in Washington State in an attempt to help salmon runs on the Columbia River system.
