After lowering its earnings guidance for 2011, blaming Berlin’s decision to phase out nuclear energy within a decade, RWE says it will widen and accelerate plans to divest some of its fossil-fuel assets.

It is understood that RWE’s UK division, npower, may be on the auction block – though likely not its renewables assets.

In addition, the company says chief executive Jürgen Grossman will step down in June 2012, three months earlier than planned.
