Hydro Generators

Hydroelectric systems require generator solutions that align with turbine design, operating conditions, and long-term performance requirements.

Orange1 America supports hydroelectric projects with PMG generator solutions engineered for reliable operation, efficient energy conversion, and integration into a wide range of hydro systems. Working with OEMs, integrators, and project teams, we help align generator configuration, cooling methods, and control requirements with the specific needs of each installation.

Our hydro generator solutions support applications ranging from small-scale hydro systems to mid-range industrial and municipal projects. Configurations are available for low-voltage systems, variable frequency drives, and direct-on-line connections.

Hydro Generator Products

Orange1 America delivers a comprehensive line of hydro generators for diverse needs. Our generator PMG options are available in multiple frame sizes and power ranges, from 10 kW up to 3000 kW. These units integrate seamlessly with Kaplan, Pelton, and Francis turbines, providing stable power output and minimal mechanical strain. 

Customers can choose between air-cooled, water-cooled, and fully submerged models, depending on project requirements. We offer flexible supply configurations, including complete generator systems or individual components for integration with existing turbines.

Advantages of PMG Generators

Choosing our PMG generators offers tangible operational benefits:

  • High efficiency across different load and speed ranges
  • Direct coupling to turbines, reducing mechanical components and maintenance
  • Low operational noise, suitable for environmentally sensitive sites
  • Null magnetizing current, reducing auxiliary power requirements
  • High power factor, minimizing the size of capacitor banks in DOL configurations
  • Compact design with high power density for limited-space installations

These advantages translate directly into lower operational costs, simpler installations, and better performance over the life of the equipment.

Product Portfolio

Orange1 America provides multiple PMG generators configurations for hydro applications:

  • Submerged PMG generators: Ideal for Bulb/Kaplan turbines, fully water-tight, ready for direct coupling
  • Water-jacket PMG generators: Efficient cooling for Pelton and Kaplan turbines
  • VFD-connected PMG generators: Precise speed and frequency control for inverter-driven systems
  • DOL PMG generators: Parallel connection to the grid for consistent power delivery

Each product is available as a complete solution, co-engineered package, or as active components for integration into existing systems. We focus on providing the right product to match each customer’s turbine, speed, and voltage requirements.

Reference Installations

Our generator PMG technology has been deployed in numerous hydroelectric facilities:

  • France Plant: 480 kW @ 176 rpm, submerged Bulb/Kaplan turbine, VFD, direct coupling
  • Babbiona Plant, Italy: Four 170 kW units, water-jacket cooled, VFD, direct coupling
  • Saint Marcel Plant, Italy: 390 kW, submerged Bulb/Kaplan, DOL, direct coupling

These installations demonstrate our capability to deliver solutions that meet exact performance and environmental requirements while providing reliable power generation.

Why Choose Orange1 America?

Hydroelectric projects require generator solutions that balance efficiency, integration requirements, operating stability, and long-term reliability.

Orange1 America works with customers to help define the right PMG generator configuration based on turbine type, speed, voltage, cooling requirements, and installation constraints. Our approach combines application support in the U.S. with the engineering and manufacturing capabilities of Orange1 Group in Italy.
