About Us

Associated Power began as a small diesel engine service company in Long Beach, California. Founded as Associated Diesel, it targeted the large population of diesel engines used in the commercial marine industry in the rapidly growing Los Angeles Harbor area.

In 1959, the company was incorporated and moved to a two acre facility in Wilmington (a district of the city of Los Angeles, California). There it branched out into the industrial, off-highway, and oil field engine markets. In 1967 Associated Diesel was made a factory authorized dealer for Detroit Diesel Corporation and Allison Transmission Division of General Motors. With expanded facilities, the business continued to grow in the on-highway diesel market and generator set market.

In 1982 the company expanded its business to handle construction equipment, and opened a 6 acre branch in San Bernardino. That same year they became a Cummins Engine full service dealer.

In 1986 the generator business expanded with the acquisition of the MQ Power WhisperWatt line of diesel generator sets, and in 1993 the Maxi-Lite light towers were added to the product line.

In 2000 we opened up a Bakersfield location and then in 2004 Associated Power moved the San Bernardino operation to Fontana California, where we are continuing to expand our generator rental business.
