What On.Energy does
On.Energy (ON Energy Storage, Inc.) is a Miami-headquartered, privately held energy technology and asset-management company that designs, develops, finances, owns, and operates hyperscale power systems centered on a patented medium-voltage double-conversion uninterruptible power supply architecture branded as AI UPS™. The platform integrates advanced power electronics (silicon-carbide grid-forming converters from EPC Power), purpose-built medium-voltage transformers (under a 5 GW supply agreement with Prolec GE), battery energy storage systems, and ON.command™, a proprietary energy management software with AI-based predictive forecasting, millisecond-level real-time dispatch, and a 24/7 Remote Operations Center. ON.energy also sells an MC UPS™ medium-voltage mission-critical power-quality product for hospitals, manufacturing, and other Tier III/IV environments. Modularity spans 10 MW to 1 GW+ per site using 3.2 MW base blocks with N+1 to 2N+1 redundancy and 20-year Tier-1 component warranties.
The company operates as a fully integrated independent power producer (IPP), technology vendor, and asset owner, monetizing assets through Energy-as-a-Service, long-term offtake, and project-finance structures, alongside grid-services revenue (ancillary services, frequency regulation, energy arbitrage) in ERCOT, CAISO, PJM, and MISO. Hardware sales and custom engineering — including 5 GW of dedicated transformer supply and multi-gigawatt integrations with Shoals Technologies — provide an additional revenue layer. Capital structuring converts Investment Tax Credits into immediate deployment velocity, with $120M in tax-equity and ITC transfer capital deployed to date. Customer segments are hyperscale AI data centers (primary), mission-critical facilities, grid/utility (front-of-the-meter), corporate and industrial energy users (Walmart, Hyatt, Glencore), and LATAM industrial and energy markets served from a Mexico City hub.

On.Energy competitors and assessment
Company assessmentDirect peers
- Fluence Energy: Largest pure-play battery energy storage IPP and technology provider globally. Directly comparable to ON.energy's grid-scale BESS and energy management software offering, with overlapping customer base in ERCOT, PJM, and CAISO and similar Energy-as-a-Service business model. SVP Sales Engineering Ismario Gonzalez previously led at Fluence.
- Powin Energy: Battery energy storage system integrator and IPP with deep presence in ERCOT and other U.S. ISOs. Directly comparable to ON.energy's BESS and grid services business lines; recently expanded into data center-adjacent storage; SVP Sales Engineering Ismario Gonzalez previously led at Powin.
Broad incumbents
- Tesla Energy (Megapack): Tesla's energy business competes with ON.energy's BESS / Grid Volatility line via Megapack, the dominant grid-scale lithium storage product. Serves the same hyperscaler and utility customers with a vertically integrated hardware, software (Autobidder), and project finance stack at much greater scale.
- Vertiv Holdings: Global leader in data center power infrastructure (UPS, switchgear, thermal) and a direct competitor to ON.energy's AI UPS and MC UPS product lines. Operates at vastly larger scale with established relationships across hyperscalers and colocation operators, and is the most natural incumbent threat to ON.energy's medium-voltage UPS differentiation.
- Eaton: Diversified power management major with a deep UPS and switchgear portfolio serving data center customers. Comparable to ON.energy's MC UPS and AI UPS lines as an incumbent alternative with greater channel reach and balance sheet flexibility for multi-gigawatt deployments.
- Schneider Electric: Global data center infrastructure major with Galaxy UPS, electrical distribution, and EcoStruxure software platforms. Direct incumbent peer to ON.energy's AI UPS and ON.command offerings, with established hyperscaler relationships and an integrated hardware-software-services business model.
- ABB: Power and automation major with UPS, power conversion, and grid-forming inverter offerings. Comparable to ON.energy's hardware stack (transformers, power conversion, grid-forming) and increasingly focused on data center power solutions as AI demand accelerates.
- Siemens Energy: Global energy technology major with grid-scale storage, power conversion, and data center power offerings. Direct comparable to ON.energy's medium-voltage AI UPS architecture and grid services software; SVP Sales Engineering Ismario Gonzalez previously held senior leadership at Siemens Energy.
Emerging players
- Stem Inc: AI-optimized energy storage and software platform focused on commercial, industrial, and data center customers. Comparable to ON.energy's ON.command EMS software and behind-the-meter storage offerings, with similar participation in ERCOT, CAISO, and PJM grid services markets.
Others
- Shoals Technologies Group: NASDAQ-listed electrical infrastructure provider (DC Recombiners, BESS Recombiners) and ON.energy's flagship strategic partner. Adjacent rather than competing — their DC Recombiner products are co-deployed with ON.energy's AI UPS — but represents a comparable go-to-market channel into hyperscalers and a publicly traded proxy for AI data center power infrastructure value.
