I HYDRO REVIE\\' / OCTOBER 19L):; Beyond 100 The criterion for selection of inductees for the Hydro Hall of Fame this year was facilities that , in 1995, have been engaged in hydroelectric power production for 100 years . We are aware of three additional facilities that have been operating for more than 100 years. They are: - Fulton. This 1.25-MW plant on the Oswego River in Fulton, New York, was commissioned in 1884. The powerhouse initially was equipped as a direct current plant for arc lighting . By the turn of the century, it was fitted with alternating current generators. Owned by Niagara Mohawk Power Corporation . the site was first developed in 1823 when the Oswego Canal Company constructed a canal to channel water from the river to provide mechanical power. - Georgetown Hydro. This 1 .5-MW plant on South Clear Creek in Georgetown, Colorado, was commissioned in 1893. Its owner, Public Service Company of Colorado, was known as Denver Gas and Electric Co . when Georgetown was built. The facility originally was equipped with one unit; a second was added in 1900 to raise the capacity to its current rating . - Mill Creek #1. This 940-kW plant on Mill Creek in Mertone, California, is owned by Southern California Edison. The facility began operating in 1893. Forty years later, a new horizontal Pelton unit replaced the original equipment. If you are aware of other facilities 100 years old or older, or plants anticipating a 1OO-year celebration in the near future , we'd appreciate you alerting us. |
