Wind power accounts for 1 percent of New York's generating capacity - the amount of electricity power plants could produce in a given moment if they ran full tilt. When it comes to the electricity actually generated and consumed over a full year - the kilowatt hours a customer would be charged for on an RG&E bill, for example - wind produces less than 1 percent.
To compare, nuclear and hydroelectric account for 27 percent of the state's capacity, but 45 percent of the actual electricity generated. Those two sources, for the time being, are the most economical in New York, says Gary Paslow, manager of communications for New York Independent System Operator, the organization that oversees the state's power grid. That's because of the rising cost of fossil fuels like natural gas and coal.
But there are caveats that go along with that number: capacity is only one part of the picture, and since developers can't control when the wind blows, it's tough to predict actual output over time; the potential capacity is based on peak, not average, output; not all of the sites will be developed; and there are physical limits to what the state power grid can handle from an intermittent power source like wind.
The last bit is crucially important as a limiting factor. The NYISO study says that, based on technical factors and physics, the grid can only handle 3,300 megawatts of wind power.
"That's what everybody has based the short-term planning for," Paslow says.
