Largest Ocean Energy Device Ever Installed in U.S. Waters Generates Electricity at Design Capacity
Advanced Technology Revolutionizes the U.S. Ocean Energy Industry
PORTLAND, ME, August 18, 2010 - Ocean Renewable Power Company (ORPC), an industry
leader in tidal, river and deep-water ocean current energy technology and projects, announced
today that its Beta Power System, the largest ocean energy "power plant" ever installed in U.S.
waters, has successfully generated grid-compatible power from tidal currents at its Cobscook
Bay site in Eastport, Maine. The system's core component, the proprietary Turbine Generator
Unit, or TGU, is deployed below ORPC's world-class research and testing vessel, the Energy Tide
2, and has a maximum design capacity of 60 kilowatts. Performance test results show that the
TGU's electrical output meets or exceeds expectations for the full range of current velocities
encountered. ORPC will use the data obtained from the Beta Power System to fine tune the
design of its commercial TidGenTM Power System, planned for installation in Eastport in late
2011. The TidGenTM Power System will be connected to the New England grid through the Bangor
Hydro Electric Company system, and will generate enough electricity to power 50 to 75 homes.
"Proving the efficacy of the Beta Power System and its ability to generate gridcompatible
power day in and day out is a huge milestone for America's ocean energy industry,"
said Chris Sauer, president and CEO of ORPC. "It reaffirms the limitless opportunities to advance
the nation's renewable energy agenda and ensure a more sustainable future." Tidal energy has
the potential to be a billion dollar industry in Maine within the next seven to ten years, creating
hundreds of jobs. The bodies of water around Eastport have some of the most robust tidal
currents in the world, and through ORPC's testing activities over the last three years, Eastport
has become known as the Kitty Hawk of tidal energy.
ORPC's Beta Power System incorporates significant new advancements and technological
innovations. These include the TGU's proprietary advanced design cross-flow turbines,
engineered with 100 percent composite materials, its permanent magnet generator, a
substantially composite support frame, and a power electronics system that converts the
generator's variable output to grid-compatible power.
Through its three-year partnership with the University of Maine, ORPC is also setting the
standard for environmental monitoring of ocean energy systems with a program to observe the
marine environment around the Beta Power System. UMaine researchers, led by Gayle Zydlewski,
Ph.D., are supervising the program, which incorporates state-of-the-art visual and acoustic
monitoring technology. Data collected will allow UMaine and ORPC to better understand and
help minimize any potential interaction between ORPC's technology and marine life.
"Development of alternative energy sources must consider the natural environment. We take
this very seriously, and we are working closely with ORPC to understand the dynamics of the
marine life where tidal power will be generated," said Dr. Zydlewski.
Over the next two months, ORPC will also be demonstrating how tidal energy can be
delivered to the U.S. Coast Guard for use at its Eastport station through a battery electrical
supply system that is charged aboard the Energy Tide 2. This is the first application of tidal
energy by a federal agency. "The Coast Guard in Maine encounters the power of the elements on
a daily basis. Capturing some of these sustainable forces to help achieve our energy needs is a
prudent and responsible thing to do. We are extremely pleased to be a part of ORPC's exciting
initiative to harness tidal energy at Station Eastport," said Captain James McPherson,
commander of the U.S. Coast Guard Sector in Northern New England.
ORPC is one of the few companies in the world to have generated electricity from ocean
currents without using dams or impoundments. The company holds FERC preliminary permits and
is in the process of obtaining FERC pilot project licenses for tidal energy sites in Maine and
Alaska, which have been designated world-class tidal resources by the World Energy Congress.
ORPC's community outreach efforts in Eastport have been cited as the model for ocean energy
development by the Governor of Maine's Ocean Energy Task Force. ORPC's work is funded in part
by Maine Technology Institute and the U.S. Department of Energy.
