Notes
Survey number HAER CA-130
Building/structure dates: 1898 initial construction
Building/structure dates: 1905 subsequent work
Building/structure dates: 1904 subsequent work
Significance: When completed in 1898, Powerhouse 1 had the longest transmission line in the country, and possibly the largest hydroelectric generators in the world. Innovative features which became industry standards include the individual tail races, internal revolving field alternators, and transposition of wires. When Powerhouses 2 and 3 were added, the system became the prototype for the larger hydroelectric systems of the twentieth century. Nominated to the National Register of Historic Places in 1985; American Society of Civil Engineers Historic and Engineering Landmark in 1985.
