Ampyx Power entered into a partnership with E.ON, a major European energy company, in April 2017. As part of the collaboration E.ON provides the test- and demonstration locations for both AP3 and its successor AP4. E.ON is responsible for the lease costs of the site, the development costs, and the costs of civil and electrical infrastructure. Ampyx Power will be able to carry out the full testing and verification program and the demonstration of both AP3 and the 2 MW at these locations. E.ON is developing the test location in Ireland, in County Mayo. In addition to the aforementioned test and demonstration projects, the demonstration of Ampyx Power’s Airborne Wind Energy Systems at sea as well as the renovation of E.ON’s first and second generation offshore wind farms are foreseen in the collaboration.
