Terzo Power Systems

What Terzo Power Systems does

Terzo Power Systems is a privately held designer and manufacturer of integrated electro-hydraulic power systems for electric and hybrid commercial vehicles and mobile equipment, headquartered in El Dorado Hills, California. The company's core Hydrapulse product family integrates a permanent magnet motor, inverter/controller, hydraulic pump, and onboard pressure/temperature sensors into a single compact unit, replacing the conventional architecture of an engine-driven pump plus separate motor controller. The product line spans electro-hydraulic steering units (EHSU-1-056, EHSU-1-075, EHSU-2) at 3-10 kW for steering applications, electro-hydraulic power units (EHPU-1, EHPU-2) at 3-10 kW for medium-duty platforms, the F3-66 at up to 66 kW rated (90 kW peak) for heavy-duty applications including mining and electric PTO, plus a high-voltage coolant pump (HCP) and AC-powered servo hydraulic solutions for industrial machine tools. The company's central technical claim is a power-on-demand architecture that delivers 80-96% energy savings versus continuously running pumps, 86% size reduction, and 87% weight reduction, verified through a three-year California Energy Commission EPIC program.

Terzo operates a B2B enterprise sales model selling directly to commercial vehicle OEMs, mobile equipment manufacturers, and industrial customers through co-development and customization engagements. Revenue derives from hardware sales of complete Hydrapulse systems and engineering services for OEM-specific integration (connector customization, firmware modifications, housing changes, pump variations). Pricing is quote-based and not publicly disclosed, consistent with low-volume, high-customization industrial sales. Manufacturing is executed through partnerships with QCC for high-volume production and Continental/Hydreco for pump technology, allowing Terzo to scale without owning heavy production assets. The company sells primarily to four vertical segments: commercial vehicle OEMs (trucking, transit, refuse), mobile/off-highway equipment (excavators, wheel loaders, construction, agriculture), industrial machine tool, and mining equipment, with named customers including SEA Electric (commercial EVs across six countries), a boom truck OEM, and Radial Dynamics (off-road racing showcase). The company underwent a CEO transition in January 2023 when Bill Pizzo succeeded founder Michael Terzo, and it has accumulated minimal disclosed outside capital beyond a $3.8M California Energy Commission grant in 2018.
