Possibly 30 East River Turbines by Mid '10


According to a post by City Limits today if Verdant's application is approved there could be as many as 30 tidal energy capturing turbines by mid 2010 in the East River just off Roosevelt Island.

The article does point out concerns for the River's wild life which has reacted well to the three turbine array but whose reaction to a 30 turbine array is unknown. Erik Baard from the Long Island City Community Boathouse, is also quoted in the article regarding his views that the existing cables "are too close to the surface, presenting hazards to boaters and kayakers. "
“They have got to create a safer cable, rope and buoy system, because what they have now is not safe enough,” Baard said. “I also emphatically don’t want them narrowing or interfering with our navigation. The cables that go to the turbines can do that.” Neither Mr. Baard nor the Long Island City Boathouse filed comments with FERC, but he hopes that Verdant will redesign the 30 turbine array so that connecting cables have more slack, allowing them to drop deeper into the water. Taylor, however, said there will be adjustments to the cables, but no radical changes.


The current turbines partially supply power to the Motorgate Parking Garage as well as the Gristedes. The article does not define where the power generated will be used but earlier reports had the energy being used to power the local Roosevelt Island F Train subway station electrical systems.

Verdant Submits New Turbine Designs for East River Power Project

The Daily News posted an article today, November 20, 2007, indicating that Verdant believes its new turbine design will finally beat the problem of the tidal currents causing damage to the blades and the turbine itself.

Verdant had originally submerged six turbines into the East Channel of the East River behind Gristedes and Motorgate. Verdant "...expects to plant two reinforced turbines for analysis as soon as February. "

Update: East River Tidal Energy


Earth News published an on-line article today updating the current status of tidal energy projects in the East River. The article is also a good summary of the technology involved.

East River Tidal Energy: Videos Regarding Turbine Removals

Each of these videos relate to the story from Tuesday where it was reported that Verdant Power has removed its turbines from the East River’s East Channel as the tides are stressing the bolts holding the propeller blades and the blades themselves. Earlier this year the tides destroyed several blades causing Verdant Power to upgrade the blades to those now being removed.

It is also reported that a second entity, Oceana, has been granted the necessary license and/or permits to begin tidal energy tests just North of Roosevelt Island within the Hell’s Gate section of the East River.

This is another link to the NY Times video I mentioned the other day. I thought it appropriate to post these together.
