Power Systems manufactured by Caterpillar and engineered, installed, and serviced by Peterson Power supply emergency stand-by power for hospitals, data and telecommunication systems, office buildings, and industrial applications. Our engines also power work boats, pleasure craft, and provide clean dependable prime power for distributed generation used in businesses and remote construction products.

Peterson Power Systems is committed to protecting the environment. We have revised our operating procedures relating to vehicle fleet maintenance, office recycling programs, facilities upkeep, and purchasing options to reflect this commitment. A major part of this program is a parts remanufacturing option we offer in conjunction with Caterpillar, in which replaced parts are returned to the factory for retooling and reuse. This significantly reduces the amount of scrap we discard each year. As a result of our green efforts, Peterson Power Systems is now a certified Bay Area Green Business. This certification demonstrates our dedication to reducing our impact on the environment with the following programs: solid waste reduction, energy efficiency, water conservation, and pollution prevention.
