BUILDING IN RHODE Island isn’t easy. Hurricanes and tropical
storms barrel through its quaint coastline towns, interrupting perfect summer
weekends. Freezing winters bring blizzards that can shut down the entire state.
And every season features corrosive salty winds, biting at the
coast as if sent by a Britain still seething at the first American colony to
declare independence.
Hooked up to the grid by the end of 2016, the system could supply
90 percent of the tourist destination’s power within the next few years.
But it hasn’t been easy. Designing and building spinning fans
hundreds of feet tall that stay sutured to the ocean floor in the face of
currents and wicked winds has taken almost three years of work.
The blades on Deepwater Wind’s turbines, which have been arriving
at Block Island over the last month, will be almost 250 feet long.
That means the top and the bottom of the rotors will be separated
by 500 feet or more.
Anything covering that much area will have to deal with widely
variable wind conditions, says Cristina Archer, a professor at the University
of Delaware who studies offshore wind farms.
