Earnings before interest, taxes, depreciation and amortisation (Ebitda) at renewables unit RWE Innogy jumped 74% to €505m ($541m) from January to September from the year-earlier period as RWE fully commissioned the 576MW Gwynt y Môr offshore wind farm off North Wales, and the 295MW Nordsee Ost near the German island of Heligoland.

"RWE Innogy is really taking off now – from a small seed three years ago it has become a model of success," RWE chief executive Peter Terium claims.
