It is designed to test the physics of how wind turbines interact in a wind array.The $4.5-million facility, dubbed SWiFT for "scaled wind-farm technology," is the result of a partnership between the U.S. Dept. of Energy, Sandia
The market is generally healthy and steadily growing, and margins are up for large specialty contractors. Further, advances in design tools and owner demand for collaboration are giving subcontractors a seat at the table early on in projects.
