“Of the nearly one hundred wind sites we visited and filmed, Over Yonder Cay had the best team work and leadership on it's 'Mill Three project.”

“When we were a new company and couldn't justify a full-time compliance engineer, we hired H2DC to manage our new product's regulatory compliance. This was my first experience where I did not have to wait on regulatory. They took a pro-active approach, worked with the labs day-and-night and did not let up until we successfully had our ISM device through compliance. Today, our company is much larger, however H2DC is still managing our regulatory compliance, and we are happy with their work.LLC ”

"What makes H2DC so special is their attention to detail even under tough circumstances.  With other integrators we've had easier state-side projects get delayed.  H2DC will order one turbine for the Bahamas, transport a crane from the states, bring in crews from the UK, Australia, some from Malaysia and the schedule won't slip a day."
