Andritz to supply generator stators for Niagara hydropower upgrade

Andritz has secured a contract from New York Power Authority (NYPA) to supply five new generator stators for the Robert Moses Power Plant, as part of a major modernization programme aimed at strengthening renewable energy supply.
The project forms part of NYPA’s Next Generation Niagara (NGN) initiative, which focuses on upgrading and digitizing critical infrastructure at the Niagara Power Project. The Robert Moses Power Plant and the Lewiston Pump Generating Plant together provide a combined capacity of 2,675 MW, making the site the largest hydropower facility in New York State and the third largest in the United States. Located near Niagara Falls, the project has been a cornerstone of the state’s renewable electricity supply since the early 1960s.
Under the contract, Andritz will design, manufacture, and deliver five 215 MVA generator stators to replace several of the plant’s 13 units. The stators, each measuring more than 10 metres in diameter, will be manufactured on-site over an estimated 10-year project timeline. The upgrade is expected to extend the facility’s operational life and improve reliability, supporting New York’s long-term decarbonization goals.
NYPA selected Andritz following a competitive tender process. The company is also currently involved in stator upgrade work at the Lewiston Pump Generating Plant under a separate contract.
“Hydropower plays an important role in New York’s growing renewable electricity generation,” said Hany Aoude, Regional Executive VP, North America, Andritz. “The new stators will upgrade one of the most significant hydropower resources in North America and help ensure reliable, carbon-free electricity for New Yorkers for decades to come.”
