Engie will have a new CEO lined up by September to lead the next stage of its energy transition strategy, its chairman told French media.

Engie’s board ousted former chief executive Isabelle Kocher in February, saying it “needs to take another step forward in transformation and to deepen the strategy launched to make Engie a leader in the energy and climate transition”.

The group – part-owned by the French government – wants Kocher’s replacement sorted out by the end of the year “which implies choosing the right candidate in September”, its chairman told French business media, reported Reuters.

Engie – which under its former name GDF Suez had a heavy gas and coal generation footprint – is ramping up its global renewable energy ambitions.

The French group last year pledged to invest €12bn ($13.1bn) in its 2019-21 energy transition programme, and was on track to install 9GW of renewables in that period.

Major initiatives include a newly-formed offshore wind alliance with Portugal’s EDP that aims to be one of the world’s biggest players in wind at sea.
