New York Power Authority - Niagara Power Project

Sienna Environmental Technologies was selected for two, four-year term contracts with the New York Power Authority (NYPA). Sienna provided hazardous materials consulting and testing services at the Niagara Power Project in Lewiston, New York. In 2006, the Power Authority completed a $300 million upgrade and modernization at the Robert Moses Niagara Power Plant. In 2012, the Power Authority began a $460 million upgrade to the Lewiston Pump-Generating Plant, which is expected to be completed by 2020.

The on-call nature of the contract required Sienna to have consultants and technicians available with little or no notice, as these multi-phased projects were often on very tight schedules. Off-hours and weekend work were routinely required to accommodate the facility owners’ needs.

The Niagara Power Project began in 1961 as the largest hydropower facility in the western world, and now generates 2.4 million kilowatts. By diverting up to 375,000 gallons per second from the Niagara River, the Niagara Power Project is able to spin turbines to power generators, converting this mechanical energy into electrical energy. This project consisted of two main facilities: the Robert Moses Niagara Power Plant (13 turbines) and the Lewiston Pump-Generating Plant (12 pump-turbines).
