What ClearGen does
ClearGen is a private, for-profit sustainable energy company founded in 2020 and headquartered in Atlanta, United States. Per its stated mission, the company is positioning itself around the transition to a more sustainable energy future, but the public-facing inputs do not disclose specific products, services, technology stack, customer segments, pricing mechanics, or geographic markets served. The website (clear-gen.com) was inaccessible at the time of data collection, displaying only a verification page, which limits insight into commercial operations.
The company has scaled to a headcount of 101-250 employees and has raised $250,000,000 in a funding round led by Blackstone Credit on 2020-09-18, with Blackstone serving as the primary financial sponsor. The co-founders are George Plattenburg (CEO) and Collin Franceschi (Chief Development Officer), suggesting an execution-and-development leadership pairing typical of project-driven energy businesses.
On 2025-08-21, CBRE Investment Management announced plans to acquire ClearGen from Blackstone, indicating the business has reached an institutional scale and strategic value sufficient to attract acquisition interest from a major global real assets and infrastructure investor. With ownership set to transfer from Blackstone to CBRE IM, ClearGen's near-term trajectory will be shaped by integration into the acquirer's broader platform.

ClearGen competitors and assessment
Company assessmentDirect peers
- Arcadia: Arcadia is a clean-energy data and procurement platform that connects commercial and residential customers to renewable energy supply, community solar, and energy management. Like ClearGen, it operates at the intersection of distributed clean energy and end-customer energy decarbonization, often through real estate and institutional channels.
- Generate Capital: Generate Capital finances, builds, and operates sustainable infrastructure — including distributed generation, storage, and energy efficiency — for institutional customers. It is closely comparable to ClearGen in deploying long-duration capital against on-site clean energy infrastructure for real-asset owners.
Broad incumbents
- ENGIE: ENGIE is a global utility and energy services company with deep renewable generation, on-site energy, and energy-as-a-service offerings for commercial and institutional customers. It competes with ClearGen in the customer-facing decarbonization and distributed-generation space, but at vastly greater scale and across many geographies.
- NextEra Energy Resources: NextEra Energy Resources is one of the world's largest renewable energy developers and operators, with significant exposure to distributed and utility-scale clean generation in North America. It is comparable to ClearGen as a developer/operator of clean generation assets serving large customers, though far broader in scope.
- Clearway Energy Group: Clearway Energy owns and operates renewable and conventional generation and storage assets across the U.S. Its focus on developing and operating clean energy infrastructure for institutional counterparties makes it comparable to ClearGen's sustainable-energy generation mandate, though at public-company scale.
- Bloom Energy: Bloom Energy designs, manufactures, and deploys on-site solid-oxide fuel cell systems that provide clean, distributed power to commercial and industrial customers. It overlaps with ClearGen in providing decarbonized generation solutions to large energy users, including real estate and institutional buyers.
- Constellation Energy: Constellation Energy is a major U.S. clean energy producer and supplier offering generation, energy management, and decarbonization products to commercial and industrial customers. It overlaps with ClearGen in the institutional clean-energy supply and on-site decarbonization space, though with much greater scale and breadth.
Emerging players
- Voltus: Voltus is a virtual power plant platform that aggregates distributed energy resources (batteries, generators, smart loads) into grid-service revenue streams for commercial and industrial customers. It is comparable to ClearGen in monetizing behind-the-meter clean energy assets, though Voltus focuses on grid services rather than customer-side generation.
- EnergyHub: EnergyHub provides a DERMS platform that utilities and energy users use to orchestrate behind-the-meter devices, EV charging, and storage. It is an adjacent peer to ClearGen, intersecting at the distributed clean-energy / building decarbonization layer, though primarily a software platform.
- GridPoint: GridPoint delivers building energy management and on-site clean energy intelligence to commercial customers, combining hardware, software, and energy services. It is comparable to ClearGen in helping commercial building owners reduce energy cost and emissions through distributed clean energy and controls.
