Energy storage represents a multibillion-dollar market at the center of the energy transition. The integration of energy storage requires software and technological solutions that play a critical role in the adoption of renewables at scale—offsetting the intermittency and reliability challenges that renewable power generation creates for the grid. Since its founding in 2009, FlexGen has supported deployments of more than 1.2 GWh of energy storage systems across the U.S. and internationally for utility, microgrid, and C&I customers. The Company’s proprietary software platform allows energy storage owners to deploy various power market strategies and combine storage solutions with any form of generation.
Kelcy Pegler, Jr., CEO of FlexGen, commented, “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.”
Olivia Wassenaar, Senior Partner and Co-Lead of Natural Resources at Apollo, said, “Energy storage assets play a crucial role in the transition to an economy powered by intermittent renewable energy sources. This transition to renewable power is happening at a time where reliability and resiliency are more important than ever for the grid in the face of increasing extreme weather events. FlexGen’s energy storage solutions bridge the gap of reliability for the grid and help accelerate the adoption of renewables by shifting renewable power consumption to times when it is needed most. We are impressed with the business that the entire FlexGen team has built and see continued tailwinds for the Company as the industry evolves.”
Apollo Partner Trevor Mills added, “We are excited to work with Kelcy, Yann, Pasi, Alan, and the entire FlexGen team to support their continued growth. We see tremendous opportunities for growth and technological innovation in the energy storage sector as the grid relies increasingly on renewable energy. FlexGen’s engineering expertise and leading HybridOS software solution position it as an ideal partner for those looking to develop and operate energy storage systems."
The company’s HybridOS solutions include six distinct energy management solution applications including: DigitalTwin, FlexPack, SiteController, FleetManager, PowerCloud and FlexBidr. FlexGen’s existing investors include Altira Group, the founding investor group led by Jerry Miller and Mark Dreyfus, Caterpillar Ventures, and GE Ventures.
The investment in FlexGen extends Apollo’s track record of investing in and lending to companies supporting the clean energy transition.
