The ESI turbine was a commercial spinoff of a US wind energy R&D project. ESI turbines were known for their large diameter (comparable to Danish turbines), high rotor speed, and tip brakes at the end of each blade. These blade brakes, or flaps, were designed to protect the turbine during high wind emergencies. Ultimately, nearly 700 ESI-54 turbines were installed in California (Altamont Pass, San Gorgonio Pass, and Tehachapi Pass).

These turbines performed poorly in California, with reliability far inferior to competitors. ESI's leaders ultimately withdrew and returned to wind projects at the US Department of Energy's National Renewable Energy Laboratory (DOE-NREL). Most of these turbines were dismantled in the early 2000s.
