Capex of an inexpensive flexible wing like NPW

That is, over 20 years, a total of €2,500,000 for a 1 MW wind turbine.

The price of our NPW would therefore be lower, assuming their lifespan is 1 year, which we do not know, knowing that we must take into account the reeling cycles which are certainly very tiring for the material, and a permanent use.

Now for AWES using NPW (or other kites), it is appropriate to add the cost of other components and the financial costs which are included in the cost of the wind turbines: generator and all the mechanics, ground station, possible electricity smoothing, reduction of secondary uses on the operating area, security measures, insurance, and so on.

It will be necessary to see the threshold of the AWE benefit when the exploitation of higher and more powerful altitude winds (possibly including the Low Level Jets (LLJs)), the saving in material (if we except the regular replacement of the kites) compensate for a lower efficiency of kites compared to wind turbine rotors, and the disadvantages linked to safety and high control requirements.
