Each turbine is anchored in "a giant, swimming pool-sized block of concrete, through which 22 soil anchors are drilled into the mountain," Johnston said. [Navy Cmdr. Jeffrey M. Johnston is the base’s public works officer.] He explained that the soil anchors are sunk 30 to 40 feet deep, then sealed with grout. "So they are essentially nailed to the mountain," he said of the turbines.The four turbines at Quantánamo are relatively modest 950-KW machines, apparently from NEG Micon, which was absorbed some time ago by Vestas. Turbines over twice their capacity, exceeding 400 feet in height, are being proposed for the wild mountains of the eastern states.
