Buttonwillow, CA San Joaquin Power (1536)

Interesting historic insignia for "San Joaquin Power," on a substation in Buttonwillow, CA. San Joaquin Power existed from 1895 to 1930, when it merged with Great Western Power which eventually became. PG&E -- which doesn't have nearly as interesting a logo. I didn't find any record of when this power plant was built but I did find that the company was providing electricity in the general area in 1915.
