Pontoon Float System Going Strong After 18 Years

摘要

In 1987, Northern States Power (NSP), now a wholly owned subsidiary of Xcel Energy in Eau Claire, Wis., replaced the boat-restraining barrier at its 23-MW Chippewa Falls hydro project in Wisconsin with an innovative new system. At the time, Hydro Review covered the innovation in "Sticky Wickets" (Volume 6, Number 5, page 62). Today, Xcel Energy, headquartered in Minneapolis, Minnesota, uses the system at 17 hydro projects to keep recreational boaters safely away from spillways.
