With EERE support, Ocean Renewable Power Company (ORPC) is conducting a two-year study on the effects of tidal turbines on endangered beluga whales in Cook Inlet, Alaska—home to some of the greatest tidal energy potential in the United States. To successfully permit and operate the tidal power project in Cook Inlet, ORPC must conduct a rigorous biological assessment of the potential and realized effects that the tidal turbines' physical presence and sound footprint could have on the distribution, relative abundance, and behavior of the whales. Prior to conducting the assessments, ORPC will collect baseline data at the proposed deployment areas near Fire Island and at the initial pilot project site near East Foreland. Researchers will compare measurement technologies and visual observation techniques and, based on the assessment results, will recommend a best practice for future data collection. When complete, this study will help the tidal industry understand the potential impacts of tidal energy projects on the belugas, which will inform future siting and operation decisions.

The Water Power Program is committed to developing and deploying a portfolio of innovative technologies for clean, domestic power generation from resources such as hydropower, waves, and tides.

The Office of Energy Efficiency and Renewable Energy (EERE) success stories highlight the positive impact of its work with businesses, industry partners, universities, research labs, and other entities.
