In response to federal safety requirements, Brookfield Power has completed a $3 million surge tank and penstock replacement program at the 4-MW Allens Falls hydroelectric plant on New York’s St. Regis River.
Brookfield said the six-month-long upgrade, completed in November, meets Federal Energy Regulatory Commission requirements to withstand a seismic event, as specified by its license to operate the plant, part of the 6.8-MW West Branch St. Regis River project (No. 10461). The work was among a series of multi-million-dollar project upgrades in New York. (HNN 1/31/07)
B-S Industrial of Gouverneur, N.Y., carried out the upgrade, which included installation of a surge tank to replace a tank that had been in service since the 1920s. Work also involved removal of 1,500 feet of penstock that carried water from the St. Regis River to the hydropower plant. Additionally, new foundations, ring girders, and 1,500 feet of new, 7-foot-diameter steel pipe were installed.
