The following assumptions were used for the calculation:

Air density 0,413 kg/m3

Efficiency rate of 53 %

Total area of all rotor blades 15.700 square meter per wind power stations, this is equal to one onshore wind power systems with a diameter of 140 m

One wind park consists of 30 high-altitude wind power stations

Using diffusors for example a "wind lens turbine" with an factor of 2,2

The costs for a transformer station are not included, because the costs are very different related to the location of the high-altitude wind power station.

Average wind speed in m/s for the period of 2010-2019 in the coordinate

A storage capacity for 6400 MWh will be build, these MWh are sold at a time with higher prices than the average wholesale price. An additional sales price of EUR 20/MWh is assumed in all regions.

Average wholesale price 2023 in EUR for the power of the wind park, 100 % of the produced power can be sold, there is no surcharge of the wholesale price, related to a less using of the national grid, because the high-altitude wind power stations can be placed everywhere.

The investment amount for 30 high-altitude wind power stations are 251,2 Mio EUR.



This includes only the costs for the high-altitude wind power station and not for the additional transformer station for the connection to the net grid of the country.
