Why two turbines and not just one, to minimize impact?

,

The two turbine demonstration project serves multiple goals. A) to demonstrate floating technology; b) to demonstrate the interaction of the two turbines in proximity to each other to generate wind power effects such as shadowing; c) to demonstrate the electrical connection of multiple turbines connected to one subsea cable; and d) to generate enough electricity for sale to pay for the project.

Test site usage is limited by state law LD 1465 to a maximum of 2 wind turbines, 3 meteorological towers per wind turbine, one submerged utility line with up to 25 MW capacity, up to 2 wave energy converters, and an ocean sensor package.
