In September 2013, a team of National Renewable Energy Laboratory (NREL) researchers, led by Vahan Gevorgian and Robb Wallen, faced a looming deadline. Not only did the brand-new 5-megawatt (MW) dynamometer need to be up and running, connected to a 2.75-MW wind turbine nacelle as a trial technology component, but the power generated by the nacelle also had to be sent through the never-before-tried Controllable Grid Interface (CGI) and back to the grid.

As if that was not enough pressure, a record flood hit the Boulder, Colorado, area near what is now known as NREL’s Flatirons Campus, where the team’s work was being conducted.
