Apollo Global completed a $150m investment in FlexGen Power Systems, a provider of energy storage technology solutions. Apollo's investment will be made in partnership with existing investors, Altira Group and the founding investment group led by Jerry Miller and Mark Dreyfus. "Our work with Apollo will accelerate FlexGen's growth, and the capabilities we can offer going forward while establishing the bankability that the market values when making energy storage investments. We are well-positioned at the most critical intersection of the clean energy transition—energy storage. We have spent the past decade building the most advanced integration solutions in the market—and now that market is ready to take-off. I'm excited to have Olivia and the rest of the Apollo team's support in building on FlexGen's mission to deliver utility-scale storage that drives forward the clean energy transition," Kelcy Pegler, FlexGen CEO.
