A ging hydro facilities present challenges, and the hydro plant discussed in this article provides an illustration of how the life of such an aging unit can be extended. The facility is located on a river in a northeastern U.S. state that was home to a number of paper mills constructed during the early 20th century, many of which were converted to generate hydroelectric power. This mill was built in the early 1900s before being converted to electric power production in 1914, when three vertical Francis turbine-generator units were installed. The plant owner still operates three units with an installed capacity of 8 MW operating at 45 feet of head.
