Renewables Rescue Stability as the Grid Loses Spin

A Stable Future from Renewables. The decrease in spin on the power grid has put the spotlight on stability. As renewables ramp up across the world, NREL has worked to recreate the subtle and extensive grid services inherent in synchronized rotations. Each solution bridges renewables a bit further toward full integration on the energy system.
