The Danish wind turbine TWT-11 weighs approximately 330 kilograms, allowing it to be transported on a standard trailer and installed without a traditional concrete foundation, according to developer KiteX and reports from the Danish publication Ingeniøren.
Testing the Lightweight TWT-11 Turbine in Denmark
At Risø outside Roskilde, the Danish company KiteX is testing a wind turbine that departs sharply from the massive industrial structures typically associated with wind power. Named the TWT-11, the unit is engineered specifically for farms and rural properties. According to manufacturer specifications cited by Ingeniøren, the entire construction weighs roughly 326 to 330 kilograms. This low weight allows the turbine to be hauled on a standard utility trailer and erected in a single day.
KiteX eliminates these heavy components by using glass fiber, lightweight guy wires, and earth anchors. The 21-meter-tall tower is held firmly in place by lines anchored directly into the ground, completely removing the need for concrete work.
Power Output and Specifications for Rural Properties
The TWT-11 features a generator with a maximum capacity of 5 kilowatts. KiteX estimates that in a suitable location, the turbine can generate around 15.000 kilowatt-hours annually. According to regional data, this output matches the average annual electricity consumption of a typical household.
The company has priced the unit at 165.000 danske kroner, with regular commercial deliveries scheduled to begin in 2027. KiteX reports that it has already secured around 100 pre-orders for the lightweight system as testing continues at the Risø facility.
Evolution from Airborne Wind Energy to Ground-Based Design
The development of the TWT-11 stems from a much more unconventional aerodynamic concept. Company founders Okholm and Mathias Neuenschwander initially focused on creating an airborne wind turbine designed to fly like a kite, according to background details from the project’s development history.
Over time, the engineering team concluded that the flying turbine concept was overly complex for practical deployment. Instead of abandoning the core mechanics entirely, the founders pivoted. They took the foundational principles of low weight and minimal material usage from the airborne project and successfully adapted them into a stationary, ground-based wind turbine.
