AGL splits dirty energy assets into separate company as renewables rise accelerates - I speak with chief executive Brett Redman

The rapid rise of renewables has forced the energy giant AGL into an aggressive survival strategy by splitting its dirty fossil fuel assets into a seperate company. 

The corporate manoeuvre where legacy coal and gas assets will be housed in a company called PrimeCo comes as AGL confronts a fundamental shift to green energy and after pressure from major investors and superannuation funds. 

But AGL chief executive Brett Redman tells ABC's Peter Ryan can't be sold off given the need to "keep the lights on" during to transition to renewables.

I also speak with Thomas Oriti on ABC NewsRadio to explain the challenge AGL is facing to deliver on the strategy.
