About Airborne Wind Energy Systems

Our planet’s survival depends on a sustainable energy future. Existing technologies create progress towards this goal, but to accelerate the energy transition we must unlock additional sustainable energy sources.

Ampyx Power aims to deliver a disruptive novel wind energy technology which allows unlocking of untapped energy resources at low costs and with limited environmental impact.

Disrupting the wind energy industry

Ampyx Power replaces steel and concrete with state-of-the-art cost effective technology to capture the vast wind resource at higher altitudes with much less material than used in conventional wind turbines.


At higher altitudes the wind is stronger and more constant. With AWES we can unlock new regions where conventional wind energy is not feasible.

  • Capturing strong and constant wind resources at 300-600m altitude
  • Expands the operating envelope of wind energy to deep sea and far inland
  • Similar output as conventional wind turbines with 90% material reduction
  • Straightforward installation, maintenance and decommissioning operations
  • Potential to entirely replace current generation wind turbines at lower costs, and with less environmental and visual impact

The technology

An automatic aircraft is tethered to a generator on the ground. It moves in a regular cross wind pattern at an altitude from 200m up to 450m. When the aircraft moves, it pulls the tether which drives the generator. Once the tether is reeled out to a predefined tether length of about 750m, the aircraft automatically descends towards a lower altitude causing the tether to reel in. Then it ascends and repeats the process.


The aircraft lands and takes off automatically from a platform, by utilizing an array of sensors which provide the autopilot with critical information to perform the task safely.

Ampyx Power has specific in-house aircraft knowledge and expertise in constructing automatic aircraft. For instance, in terms of the algorithms the automatic pilot is equipped with. Many code lines in the software ensure that the aircraft can fly completely automatically while responding to changes indicated by numerous sensors. Adjustments can be made within milliseconds, allowing the aircraft to continuously fly in its pattern.
