Hydro Power Parts Machining and Manufacturing

Large Precision Parts for Hydroelectric Infrastructure

Greno Industries specializes in high-precision hydro power machining and manufacturing for hydroelectric facilities across the Northeastern United States, Canada, and beyond. 

From our manufacturing facility in Scotia, New York, we combine multi-axis CNC machining with strict quality control to provide large-scale components for conventional hydro, pumped storage, and run-of-river plants.

Why Partner with Greno for Hydropower Projects?

Hydroelectric infrastructure demands absolute reliability to minimize unplanned downtime. Greno Industries bridges the gap between massive industrial scale and micron-level precision.

  • Heavy-Duty CNC Capabilities: Large-envelope CNC milling and turning centers capable of handling massive, high-tonnage raw castings and forgings.
  • Wear & Corrosion Expertise: Extensive experience working with heavy industrial alloys, including nitrided steels, bronze bushings, and cavitation-resistant stainless steels (e.g., Grade 304 and 316).
  • AS9100 & ISO 9001 Certified: Strict quality management protocols providing 100% material traceability and compliance with strict Department of Energy (DOE) and regional utility standards.
  • 24/7 Emergency Support: Located in the heart of New York’s industrial corridor, we offer 24-hour emergency manufacturing service to minimize outage durations during critical repairs.

Metal Machining for Hydroelectric Projects

Power generation components must withstand heat, corrosion, pressure, and mechanical stress. Greno works extensively with metals such as:

  • Inconel 718 and 625
  • 17 4 PH stainless steel
  • Hastelloy alloys
  • Carbon steels
  • Alloy steels
  • High temperature stainless steels
  • Copper and bronze alloys

These materials are selected for strength, oxidation resistance, thermal stability, and fatigue performance. Our machinists understand how to work with these alloys to achieve precise, repeatable results.

Hydroelectric Component Manufacturing

We support both new facility construction and legacy plant rehabilitation, manufacturing complex geometries from your exact CAD models or through custom engineering prints.

Core Turbine & Generator Components

  • Wicket Gates & Stay Vanes: Precision-milled profiles to optimize water flow dynamics and withstand high hydraulic pressures.
  • Runner Hubs & Blade Elements: Multi-axis machining for Francis, Kaplan, and Pelton turbine configurations.
  • Shafts & Couplings: Large-diameter turning and keyway cutting for main generator shafts.

Flow Control & Mechanical Systems

  • Valve Components: High-tolerance seats, stems, and gates for rotary, butterfly, and spherical shutoff valves.
  • Bearings & Bushings: Custom-machined self-lubricating bronze and composite bearings for gate operating mechanisms.
  • Locking Rings & Fasteners: Heavy-duty, corrosion-resistant hardware tailored for high-vibration underwater environments.

Precision Machining for Complex Parts

Greno’s power generation solutions are built on advanced CNC machining capabilities, including:

  • Multi-axis CNC milling
  • Large diameter turning
  • Deep hole gun drilling

Our CNC equipmentallows us to produce intricate geometries, maintain tight tolerances, and deliver consistent quality across production runs. We collaborate closely with engineering teams to optimize manufacturability, reduce waste, and improve cost efficiency.

Supporting Northeastern U.S. Infrastructure

The Northeast United States is home to a significant concentration of hydroelectric facilities, including conventional hydro stations, pumped storage plants, and municipal utility power systems. As utilities continue investing in renewable energy generation, equipment modernization, and life-extension programs, dependable manufacturing partners are critical to maintaining reliable power production.

Located in Scotia, New York, Greno Industries is well positioned to support hydroelectric operators throughout New York, New England, and the surrounding Northeast region. Our team manufactures precision-machined components for planned maintenance outages, refurbishment projects, equipment upgrades, and emergency repair requirements.

From turbine and generator components to valve hardware, fasteners, shafts, and mechanical assemblies, Greno Industries helps hydroelectric facilities maintain safe, efficient, and reliable operation of critical infrastructure.
