So we would need this 9% as backup energy and a rated backup power of 26% of the wind turbine capacity. This could be produced from gas turbines, costing roughly 250 €/kW.
The investment in the backup system is about 7% of the investment in the wind turbines. This means that costs for the backup system would not at all be a dominant factor of the system‘s economy.
