Hugh Osmond's APR Energy is readying a plan to turn it into a business with a revenue of $1bn (£0.6bn) within five years.
Serial entrepreneur Mr Osmond used Horizon, his listed acquisition vehicle, to purchase the US group APR last month. Horizon shares were suspended, but the group will trade again from September as APR Energy.
John Campion, APR's chief executive, said the plan will detail how the group, which supplies power to areas that have temporary energy gaps, will "look to follow in the footsteps of Aggreko", the market leader. Revenue was $126m last year and has grown strongly since 2004, but Mr Campion said a London listing would be a significant boost. Last week, it emerged that Mr Osmond is planning a successor vehicle to Horizon, which will list in October.
