Energy Acquisitions in Illinois
Illinois Energy Deals: Power, Solar, Storage
Energy acquisitions in Illinois center on capabilities that help customers build, connect, and operate power—from grid-scale development and data center power delivery to solar and distributed energy systems.
Across recent transactions, several buyers appear repeatedly, including LS Power, Qualus Corporation, Priority Power Management, Beam Global, and Babcock & Wilcox Enterprises. The deals often expand engineering, program management, construction oversight, and energy procurement so platforms can move customers from early development through long-term operation.
While the geography stays Illinois-based, the underlying themes span multiple energy subsectors, such as community solar portfolios, battery and EV-related energy products, low-carbon subsurface work, and nuclear-adjacent radiological engineering support.
What Stands Out
- Data center power & grid-scale siting: Scale acquired Reload to strengthen gigawatt-scale data center energy development and speed-to-power.
- Solar and community solar portfolios: Aspen Power acquired a 14.1 MWdc Illinois community solar portfolio; Babcock & Wilcox expanded its solar services via Fosler Solar.
- Program management and engineering advisory: Qualus acquired Planet Forward Energy Solutions (PFES) to expand construction management, project controls, and data analytics.
- Nuclear engineering and radiation capabilities: SI Solutions acquired Radiological Solutions to broaden nuclear chemistry, radiation management, and monitoring equipment expertise.
- Distributed energy and storage platforms: LS Power rebranded GI Energy as Endurant Energy to scale microgrids and battery energy storage; Beam Global acquired AllCell Technologies for battery engineering and manufacturing.
