ANDRITZ Lands Contract to Modernize NYPA’s Niagara Hydropower Plant

Why It Matters

Modernizing one of the nation’s largest hydropower assets strengthens New York’s renewable supply and helps meet state decarbonization goals, while showcasing ANDRITZ’s expertise in large‑scale turbine components.

Key Takeaways

• ANDRITZ wins contract for five 215 MVA generator stators
• Stators replace several of 13 units at Robert Moses Power Plant
• Project part of NYPA’s Next Generation Niagara upgrade, spanning ~10 years
• Upgrade aims to extend plant life and boost renewable reliability

Pulse Analysis

New York’s Niagara Power Project, the state’s largest hydroelectric source and the third‑largest in the United States, has been a cornerstone of regional electricity supply since the 1960s. The complex includes the Robert Moses Power Plant and the Lewiston Pump Generating Plant, together delivering 2,675 MW of clean power to utilities, municipalities and rural cooperatives. As the grid evolves toward higher renewable penetration, aging infrastructure poses reliability risks, prompting the New York Power Authority to launch the Next Generation Niagara (NGN) program, a comprehensive modernization and digitization effort.

ANDRITZ’s newly secured contract focuses on delivering five 215 MVA generator stators—each over 10 meters in diameter—designed to replace several of the existing 13 units at Robert Moses. The stators will be fabricated on‑site, a logistical choice that reduces transportation challenges for such massive components. By integrating advanced materials and digital monitoring capabilities, the upgrade promises higher efficiency, reduced downtime, and extended operational life, aligning with NYPA’s goal to keep the plant running reliably for decades. The contract follows an open competitive solicitation, underscoring the authority’s commitment to transparent procurement and best‑in‑class technology.

The broader impact of the NGN upgrades extends beyond a single facility. Enhancing the reliability of Niagara’s hydro output bolsters New York’s renewable energy portfolio, helping the state meet its aggressive carbon‑free electricity targets for 2030 and beyond. For the industry, the project signals robust demand for high‑tech turbine components and validates the business case for retrofitting legacy hydro assets rather than building new plants. As utilities nationwide grapple with aging infrastructure, the Niagara modernization serves as a blueprint for leveraging proven renewable resources to achieve grid resilience and climate objectives.
