First Commercial, Grid-Connected, Hydrokinetic Tidal Energy Project in North America
Ocean Renewable Power Company’s (ORPC) TidGen™ device has a rated capacity of 150 kilowatts and generates enough electricity annually to power 25 to 30 homes.
R&D Opportunity
Advanced water power technologies include devices capable of extracting electrical power from waves, water currents, and ocean thermal temperature differences. They also included technology advancements that would (1) enable cost-competitive development of new hydropower resources such as hydropower projects built on conduit or water conveyance systems, existing non-powered dams, or small-scale pumped storage projects, or (2) lead to improvements in the efficiency and/or environmental performance of existing hydropower and pumped storage facilities. In FY 2010, the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy funded research and development activities designed to accelerate the technology evolution of advanced water power.
Solution
DOE STTR funding was used to refine the Ocean Renewable Power Company’s (ORPC) TidGen™ Power System cross flow turbine foils. In 2012 the TidGen™ became the first commercial, grid-connected, hydrokinetic tidal energy project in North America. This is the only ocean energy project, other than one using a dam, which delivers power to a utility grid anywhere in North, Central, and South America.
In late summer 2012, ORPC completed installation of the first TidGen™ Power System at the Cobscook Bay, ME, including a local on-shore station. This first TidGen™ device has a rated capacity of 150 kilowatts and generates enough electricity annually to power 25 to 30 homes.
Impact
After running and monitoring the initial TidGen™ system for a year, ORPC will install additional power systems over the ensuing three years to increase the project's output to up to 5 megawatts – enough electricity to power 1,200 Maine homes and businesses with clean tidal energy. Since 2007, ORPC has invested more than $21 million into the Maine economy through spending in 13 of the state’s 16 counties, and has created or retained more than 100 jobs statewide. This includes over $5 million spent locally and providing employment to more than three dozen contractors, as well as local spending on goods and services.
