US Tidal Power Connected To Grid For First Time

An offshore turbine is finally spinning in the United States. This marks the first time that any offshore power generation facility has fed electricity back to a utility grid in the United States. Location: Cobscook Bay, part of the bigger Bay of Fundy, off the Maine coast. The TidGen has a peak power output of 180 kilowatts. The company plans on installing another two turbines in the same location in the fall of 2013. End target, possibly 5 MW. The TidGen device, installed in water depths of 15 to 30 meters, takes advantage of water flowing in and out of the bay as the tides change. The Bay of Fundy as a whole is an enormous tidal power resource; ORPC says that 100 billion tons of water flow in and out of the bay every day, with tidal ranges as high as 15 meters. Combined, wave and tidal power have fairly massive potential, up to as much as 15 percent of the U.S. electricity demand according to reports from the Department of Energy.
