The first hydroelectric installation
in California for long-distance transmission of alternating
current at high voltage was built in 1892 on San Antonio
Creek below this spot by the San Antonio Light and Power
Company organized by Dr. Cyrus Grandison Baldwin, President
of Pomona College. The first high-voltage transformers
built by George Westinghouse for this installation provided
for transmission of 10,000 volts from the plant to Pomona.
