German utility RWE has a renewable project pipeline of more than 18 gigawatts (GW), mostly in the United States, it said on Monday, confirming it could pour up to 3 billion euros ($3.3 billion) into green energy sources a year. RWE has transformed itself by taking over the renewables activities of subsidiary Innogy and peer E.ON , which was part of a major reshuffle of Germany’s power sector. The move has turned RWE into Europe’s third-largest renewables group after Spain’s Iberdrola and Italy’s Enel.
