The Energy Department today released the 2014 Hydropower Market Report, the first ever report to quantify the current size, scope, and variability of our nation’s hydropower supplies. The study shows the significant growth in the American hydropower market, which has expanded by nearly 1,500 megawatts over the last decade, supported more than 55,000 direct jobs across the country, and helped offset 200 million metric tons of carbon emissions per year, equivalent to the emissions from more than 42 million passenger vehicles. The report also highlights how hydropower can support the rapid integration of other renewable energy sources into the electric grid – supporting the Obama Administration’s goal of doubling our nation’s renewable energy supply again by 2020.
“This report outlines the diversity of our nation’s hydropower fleet, shows its tremendous contribution to the U.S. clean energy mix, and points to a promising future of growth,” said Assistant Secretary for Energy Efficiency and Renewable Energy David Danielson. “With an expanding industry and continued investment, hydropower remains one of our nation’s most cost-effective and reliable sources of renewable energy, and provides an important tool for boosting our clean energy supply.”
The hydropower industry has come a long way since the first hydroelectric plant came on line in in 1882. For more than 100 years, hydropower has delivered a source of clean, renewable electricity in almost every state. With nearly 80 gigawatts (GW) of installed capacity nationwide, hydropower currently supplies more than 7 percent of our electricity – enough to power more than 20 million homes.
The 2014 Hydropower Market Report highlights America’s investment of at least $6 billion in strengthening the existing U.S. hydropower fleet throughout the last decade. The report shows that the current American hydropower manufacturing supply chain spreads across 38 states, with more than 170 companies producing one or more of six major hydropower components: turbines, generators, transformers, penstocks, gates, and valves.
Developed in partnership with the Energy Department’s Oak Ridge National Laboratory, the 2014 Hydropower Market Report also presents a first-of-its-kind analysis of the current project development pipeline in the hydropower sector, supporting the revitalization and development of hydropower for generations to come. America has more than 77 GW of untapped hydropower resource potential, and continues to innovate to help unleash that potential. By making use of existing water resources and infrastructure, the vast majority of new hydropower projects built over the last decade have added electric generating equipment to dams that were previously not powered. The current hydropower development pipeline contains a diverse mixture of projects proposed at non-powered dams, conduits, and previously undeveloped rivers and streams.
The report also showcases how hydropower provides flexibility to the nation’s power grids, allowing utility operators to quickly fulfill spikes in electrical demand – such as those caused by summer heat waves – making hydropower a vital asset to many states’ energy portfolios. Further expanding this system flexibility, more than 50 pumped-storage hydropower projects, which function as large energy storage systems for other clean energy sources, are in the various stages of planning and development and will add strength and stability to our electric grids.
The Department's Office of Energy Efficiency and Renewable Energy accelerates development and deployment of energy efficiency and renewable energy technologies and market-based solutions that strengthen U.S. energy security, environmental quality, and economic vitality.
