Caterpillar engines and engine systems provide power to the world. Our engines provide power to trucks, ships and boats, our own construction and mining machines, and much more. Electrical power systems supply both primary and standby power for a variety of uses - like off-shore oil rigs, huge mines in remote deserts or mountain ranges, entire communities in areas not close to a utility power grid, hospitals, schools, factories, airports and office buildings.
