• Verdant Power now has five turbines in the east channel just north of the Roosevelt Island Bridge. Each has a different internal gearing ratio in an effort to discover the ideal setup before hundreds are built for a full roll-out. Turbines 4 and 5 are supplying power to Motorgate lighting; one carries a test load; the rest are supplying power to Gristede’s. The project is known as RITE – for Roosevelt Island Tidal Energy.
