The future has arrived.
On Monday, energy company Deepwater Wind announced that its wind farm three miles off the coast of Block Island, Rhode Island, has the all-clear to sell electricity to the regional power grid.
US offshore wind finally meets the ocean floor
The Block Island Wind Farm is the first offshore wind energy plant in the US, and it’s expected to produce 30 MW of electricity at full capacity. Deepwater Wind is slowly ramping up energy output and still must provide additional paperwork to the Rhode Island Coastal Resources Management Council, but the executive director of that organization, Grover Fugate, told the Providence Journal, “we don’t anticipate any major issues” to getting the wind farm fully online.
The one hitch in the Deepwater plan is that one of the five turbines was recently damaged when a drill bit was left in a critical part of turbine. According to the Providence Journal, “the bit had caused damage to an unspecified number of the 128 magnet modules that line the circular generator and are critical to producing energy.” Although the magnet modules can apparently be replaced easily, Deepwater needs to have the components shipped from France, where General Electric, the manufacturer of the wind turbines, makes them.
For now, four turbines capable of churning out 6 MW of power each are operational. After completing the assembly of turbines in August, Deepwater spent the next several months testing the turbines and periodically delivering power to National Grid, the regional energy provider.
The Providence Journal notes that National Grid will pay Deepwater Wind 24.4 cents per kilowatt hour of power, with the price escalating over time to 47.9 cents per kilowatt hour. Because the residents of Block Island have some of the most expensive electricity rates in the nation, they will actually see energy savings, despite the price. Mainland Rhode Islanders, on the other hand, will pay an extra $1.07 per month on average.
