America’s First Offshore Wind Farm

The first offshore wind farm in the United States, the 30 megawatt, 5 turbine Block Island Wind Farm is scheduled to be online in 2016. Soon, the Block Island Wind Farm will not only supply most of Block Island’s power, but also reduce air pollution across southern New En- gland for years to come.

What happens if there is a big storm like a hurricane? The turbines and their foundations have been designed to withstand the worst weather conditions we expect to see at the site. When the FAQ wind reaches very high speeds (approx. 56 mph), the nacelles and blades will pivot away from the wind to minimize resistance. How much energy will it produce? What happens in extreme temperatures? The Block Island Wind Farm has a total generating The turbines have builtin climate control systems capacity of 30 megawatts and is expected to that will cool the turbines down in very hot produce over 125,500 megawatt hours each year, temperatures, and keep the turbines from enough to power 17,000 homes. The wind farm is accumulating ice and snow in very cold expected to supply more than 90% of Block Island’s temperatures. annual energy needs. However, only 10% of the wind farm’s energy will be used on Block Island with the rest exported to the mainland power grid.
