The formal renaming will take place on 1 September 2016 and replace the temporary name RWE International.

The new Innogy subsidiary has a broader scope than RWE's former RWE Innogy division, which only catered for renewables but didn't include the grids, infrastructure and retail business.

"The energy market of the future is green, decentralised and digital – that's what our new brand stands for," chief executive Peter Terium said.
