What type of technology i being used to take advantage of tidal power in new york?

They are using Hydro power

New York is the largest hydroelectric power producer east of the Rocky Mountains and is fourth in the nation in the generation of electricity from hydropower. More than 300 hydroelectric generating stations - some very small, a few very large and many in between -- connect to New York's electric grid. Hydro plants typically meet at least 17 percent of the state's total electricity demand with renewable, clean and inexpensive power
