Tidal Hydropower

Font Size: A | A | A

Traditionally, when we think of hydropower, we think of it in the context of a dam, a reservoir, and a powerhouse. However, because our nation is facing an ever-increasing demand for energy, we are witnessing many new technologies surface, such as solar and wind. One of these emerging technologies is tidal power – a way of harnessing ocean energy from the tides ebb and flow through bays, inlets, and rivers.

Recently a slew of tidal power preliminary permits have been filed with the Federal Energy Regulatory Commission in costal regions of the country. Tidal power technology can take many forms, but generally projects are damless and take the form of underwater rotating turbines.

The idea of generating hydroelectricity from a technology that does not impound water and block miles of upstream fish habitat is exciting. However, tidal energy is a new technology and we have yet to fully understand its impacts. The Hydropower Reform Coalition will continue to monitor these projects to ensure that tidal hydropower projects are not rushed to development without a thorough understanding of their impacts on aquatic ecosystems.
