Verdant Power
Crews lowered an electricity-generating turbine into the East River in December. Six were installed, but they have been shut down for repairs.

From the eastern edge of Roosevelt Island, the past and perhaps the future of New York power are on display.
Just south of the Roosevelt Island Bridge to Queens rise the smokestacks of KeySpan’s giant Ravenswood electricity generating station, a behemoth that runs on natural gas and fuel oil.
North of the bridge, black cables snake out of the churning surface of the East River. They connect a makeshift control room inside an old shipping container on the island to a battery of futuristic mechanisms that could shape an energy future that does not pollute or use foreign oil — if a five-year-old company named Verdant Power can work out all the bugs.
Weeks after they were formally dedicated by Mayor Michael R. Bloomberg, six underwater turbines that turn the river’s currents into electricity have been shut down for repairs and a basic redesign. The East River’s powerful tides have been wreaking havoc with the giant turbine blades since the first two were installed in December.
“But the good thing is that there’s more power in the East River than we thought,” said Mollie E. Gardner, a geologist for Verdant Power, which owns the equipment.
This is the reality of new energy projects, which often seem more attractive on paper than they do in practice. Verdant’s principals, along with the state officials who have supported the project with large grants, say the setback is only temporary, even expected — a way to work out the kinks before moving onto the next, expanded phase.
Despite a string of mishaps that has taken a bit of the luster off the project, there is still sufficient optimism about tidal power to attract investments, and even some old-fashioned competition.
It has been a rough eight months for Verdant. Days after the first two turbines...
