Until Liberty, conventional wind turbine architecture had essentially remained unchanged since the modern industry's beginnings in the early 1980's - over the years it has been simply scaled up again and again. Over recent years, at multi-megawatt proportions, this architecture has been pushed to its design limits, resulting in increasing component failures and rising unscheduled maintenance costs.

Recognizing wind's technology constraints, in 2001 Clipper began discussions with proven wind energy thought leaders. With an aim to design the next generation of wind turbine architecture, Clipper's design team consulted with thought leaders in wind turbine design engineering, leaders in construction and operation of many of the world's mega-scale wind projects, and leaders in the service and customer support of fleets among the industry's largest. The result - robust architecture appropriate in structure and economy of operation with an abundance of crew safety benefits, turbine health monitoring advancements for preventive maintenance, and economical installation advantages.
