Plant operators typically need to schedule outputs in advance, about 14 to 36 hours. Energy storage can also provide wind leveling, which assures that actual plant output matches scheduled output. If actual wind output is below what was scheduled, the energy storage makes up the difference with energy stored when demand was low.
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
