What One Energy does
One Energy is an Ohio-based industrial power company that develops, owns, and operates behind-the-meter distributed energy infrastructure for commercial and industrial customers. Founded in 2009 and headquartered in Findlay, Ohio, the company deploys on-site generation assets including solar arrays, battery storage, peaking engines, substations, and fuel cells, with the stated mission of decarbonizing manufacturing, enabling customer control over energy assets, and building a customer-centric power grid. The company historically operated with 51-100 employees and maintained an industrial campus presence in Findlay, where it deployed a 2.3 MW solar array as part of its low-carbon generation portfolio.
The company's business model centers on long-term contracted behind-the-meter energy solutions for industrial clients, complemented by an energy advisory capability. Revenue mechanics derive from project development and ownership, operations and maintenance services, and advisory/consulting engagements. One Energy pursued inorganic growth selectively, acquiring Cancalia Engineering & Consulting in 2016 to add technical and engineering capabilities, and secured multiple rounds of capital over its history including a $1.1 million raise in 2013, an $80 million round led by Prudential Capital Partners in September 2020, and additional capital events thereafter.
In February 2026, One Energy's business interests (referenced in public communications as "One Power Company") were acquired by OnSite Partners, LLC, a behind-the-meter distributed energy platform owned by funds advised by Basalt Infrastructure Partners. The transaction folded One Energy's Findlay industrial campus and operational, maintenance, and construction capabilities into a larger platform operating 90+ projects and over 250 MW of generation under long-term contracts across 21 states. The combined entity now spans solar, battery storage, peaking engines, substations, and fuel cells with a national footprint and an advisory business serving clients in 50 states.

Company assessmentDirect peers
- OnSite Partners: OnSite Partners is the acquirer and now parent platform of One Energy's operations. It develops, owns, and operates behind-the-meter power infrastructure across the US with 90+ projects and 250+ MW under long-term contracts — directly comparable as a behind-the-meter distributed generation operator serving C&I customers.
- Enchanted Rock: Enchanted Rock provides behind-the-meter resiliency solutions using on-site natural gas generators and microgrids for commercial and industrial customers. Directly comparable to One Energy's focus on industrial customers seeking reliability and cost savings via distributed generation.
- Bloom Energy: Bloom Energy designs and deploys on-site fuel cell power generation systems for commercial, industrial, and data-center customers under long-term energy-as-a-service contracts. Directly comparable to One Energy's behind-the-meter industrial power model, including the use of fuel cells noted in the parent's asset mix.
Broad incumbents
- ENGIE Distributed Energy: ENGIE's distributed energy business develops, owns, and operates on-site energy solutions (CHP, solar, storage, microgrids) for commercial and industrial customers in North America. Highly comparable as a large behind-the-meter energy-as-a-service provider, though broader in scope and geography than One Energy.
- PowerSecure (Southern Company subsidiary): PowerSecure, a Southern Company subsidiary, designs, builds, owns, and operates distributed generation and microgrid systems for commercial and industrial customers. Comparable as a turnkey behind-the-meter distributed energy provider with deep utility backing.
- Generac Industrial Power: Generac's Industrial Power business provides on-site natural gas generators and microgrid systems for C&I customers seeking resilience and demand management. Comparable as an industrial behind-the-meter generation provider, though Generac is primarily an equipment manufacturer rather than a long-term asset owner.
Emerging players
- Capstone Green Energy: Capstone Green Energy manufactures and deploys microturbine-based on-site power and CHP systems for industrial and commercial customers. Comparable as a provider of behind-the-meter industrial generation, though smaller and more equipment-focused than One Energy's full service model.
- Redaptive: Redaptive delivers behind-the-meter energy efficiency and distributed energy solutions to commercial and industrial customers under energy-as-a-service agreements. Comparable business model focused on C&I decarbonization and on-site energy infrastructure.
- Noresco: Noresco provides energy efficiency, distributed generation, and energy infrastructure services to industrial and institutional customers. Comparable as a turnkey behind-the-meter energy solutions provider serving manufacturing-adjacent markets.
Others
- Eaton: Eaton provides electrical power management, microgrid controls, and energy storage systems used in behind-the-meter industrial applications. Comparable as a technology and equipment provider enabling the same industrial behind-the-meter solutions One Energy deploys, though Eaton is a supplier rather than an asset owner.
