The 288MW offshore wind farm is located 40km away from Helgoland island, where the operations and maintenance center for the wind farm is located.

The project with 80 units of Siemens SWT-3.6-120 turbines will be capable of producing clean energy that will be enough to power around 300,000 households annually, while reducing over 740,000 metric tons of carbon emissions.

Construction on the facility commenced in last January where the first turbine began generating electricity in May 2015.

E.ON management board member Bernhard Reutersberg said: "We’ve commissioned two large offshore wind farms – Amrumbank West and Humber Gateway off the U.K. coast – in just one year.

"Both were completed on time and on budget, which underscores our ability to expand renewables."

Additionally, the company is to begin construction on the 400MW Rampion offshore wind farm off the south coast of England in January 2016.

E.ON, along with three partner organizations, is field testing wireless, inductive charging for electric vehicles (EV) in and around Berlin.

This technology, which is provided by SEW Eurodrive, is said to transfer energy by means of a magnetic field created between inductive coils mounted in a floor pad and on the underside of the vehicle.

The project is being backed by the German Federal Ministry for the Environment, Nature Conservation, Building, and Nuclear Safety.
