September 26 (Renewables Now) - A group led by US floating wind foundation specialist Principle Power Inc has won a USD-3.6-million (EUR 3.3m) grant from the US Department of Energy to develop digital twin software for floating offshore wind applications.

Specifically, the consortium has been awarded the largest share of a USD-26-million funding package by the Advanced Research Projects Agency-Energy (ARPA-E) as part of the Aerodynamic Turbines Lighter and Afloat with Nautical Technologies and Integrated Servo-control (ATLANTIS) programme.

The partners will use it to develop, validate and operate the so-called DIGIFLOAT digital twin model -- a real-time, high-fidelity numerical representation of the 25-MW WindFloat Atlantic floating wind farm off the coast of northern Portugal.

In addition to Principle Power, the group of partners includes Swiss digital technology firm Akselos Inc, the American Bureau of Shipping, the University of Washington-Applied Physics Laboratory, the University of California Berkeley, US Naval Surface Warfare Center, Carderock Division and EDP Renewables North America Offshore.

The three-turbine WindFloat project is owned by Windplus SA in which EDP Renovaveis SA (ELI:EDPR) holds a 54.4% stake. France’s Engie SA (EPA:ENGI) controls 25%, while Spanish oil company Repsol SA (BME:REP) and Principle Power hold 19.4% and 1.2%, respectively.

(USD 1.0 = EUR 0.914)
