First New Turbine Arrives Signaling Major
Milestone in Project Modernization

FOR IMMEDIATE RELEASE
MASSENA—The Life Extension and Modernization Program at the
St. Lawrence-Franklin Delano Roosevelt Power Project
moved a giant step forward with the arrival of the first new turbine on Wednesday, May 2.
The arrival of the turbine marks a significant highlight in the modernization of the
projects 16 generators.
Replacing the turbines is part of the 15-year, $254-million Life Extension
Modernization to ensure reliable and efficient power production for the future. Turbines
will be replaced at the rate of about three units every two years to minimize production
"Beginning turbine replacement is a milestone in modernization for the St.
Lawrence-FDR Power Project," said Joseph J. Seymour, chairman and chief executive
officer of the New York Power Authority. "This high priority effort is part of
Governor George E. Patakis vision of extending the Power Authoritys ability to
produce clean, dependable, low-cost energy and preserve jobs in the North Country."
This turbine was manufactured by Alstom Power in Tracy, Quebec and made the 155-mile
trip by truck to Massena on May 2. It is 19 feet wide, 12 feet high, weighs 40 tons and is
made of stainless steel. The turbinewhich resembles the propeller of a power boat
motoris connected to a generator. Water rushing through the Robert Moses Power Dam
turns the turbine-generator assembly producing electricity.
Among the design advances in the new turbines are a more efficient shape which will
improve efficiency by getting more power out of the same amount of water. Also, the use of
stainless steel, instead of carbon steel, will make them more resistant to wear and reduce
After arrival, the turbine will be hoisted by crane onto a 24 foot wide steel table for
assembly with other turbine components, including the turbine shaft. The turbine and shaft
assembly will then be moved to the dam and installed in the turbine bore where the
original turbine-generator was located.
The Life Extension Modernization began in 1998 and is expected to finish in 2013. Under
this ambitious program most of the original 40-plus year-old equipment in the power house
at the Robert Moses Power Dam will be replaced or renovated to ensure reliable and
efficient power production for the future.
Other recent efforts in the modernization include completion of the renovation to a
90-ton-capacity crane atop the power dam and rehabilitation of the 300-ton crane that
travels the length of the generator deck to remove major parts for repair. The detailed
design is just about complete; and all major contracts for the first eight turbines,
generator rotor poles, exciters and the new communications system for operating the
turbine units have been awarded. Other major components such as the circuit breakers and
exciters have been manufactured, tested and delivered.
