RWE to Build Airborne Wind Test Centre in Ireland

RWE is to establish its first test centre to investigate the potential of airborne wind energy generators in the Republic of Ireland.

Planning permission to build the new facility in County Mayo has now been granted and construction of the site infrastructure is expected to begin later this year.

RWE is delivering the test site in partnership with Ampyx Power, a Dutch company that is developing the innovative wind energy technology.

RWE’s test site will first undertake testing, verification and demonstration of a 150kW demonstrator system, followed later by a larger commercial scale 1MW system.

RWE will also test systems from other AWE developers during the eight-year operational lifetime of its test centre.

Airborne Wind Energy Systems harness the strong and steady winds at altitudes greater than several hundred metres, and with reduced infrastructure costs.

The system being tested by RWE consists of a ground-based winch generator, a launch and land platform, and small, aircraft-shaped device.

The device, which has a 12-metre wingspan, is connected to the generator by an ultra-strong tether.

It draws the tether from the winch and produces electricity by acting against the resistance of the built-in generator.

Once the tether is fully extended, the device glides back towards the winch, as the tether is reeled back in.

Retrieving the tether requires just a fraction of the electricity generated, resulting in net power production.

This cycle is performed repeatedly, producing clean, low-cost electricity.

RWE’s test centre is supported by the Interreg North-West Europe funding programme, which was set up by the EU.

Its MegaAWE project, of which RWE and Ampyx are partners, was set up to support technology development and commercialisation within the airborne wind energy sector.

Ampyx Power, founded in 2009, is one of the leading companies in the emerging Airborne Wind Energy sector.

Fabrizio Nastri, CEO of Ampyx Power said: “After 12 years of hard work and multiple generations of smaller prototypes, we are excited to start operating our technology demonstrator on a 150 kW scale in Ireland in a real operational environment.

“The collaboration with RWE and incorporating their vast experience of wind energy into in our product design is a big step toward commercialising our technology.”
