Caterpillar engines are providing reliable power to numerous applications in the commercial and industrial sectors in the Greater China Region.

Caterpillar generator sets provide reliable prime and critical standby power for international airports (e. G. Hong Kong and Taipei), commercial buildings (e. G. Jinmao Building in Shanghai, the tallest building in China), manufacturing plants (e. G. Yue Yuen Industrial in Dongguan, the world's largest shoe manufacturer), hospitals (e. G. Shanghai Children's Medical Center) and telecommunication systems (e. G. Ground satellite stations in the region) where uninterrupted power supply is vital to operations.

For natural resources exploration, Caterpillar 3400, 3500 and 3600 Series engines and generator sets are used at Daqing, Bohai and other major oil fields where some of the older Cat engine models - such as D399 - are still contributing to production.

In the Xinjiang oil field, Cat gas engines are used for natural gas re-injection. At sanitary landfill sites in Hong Kong, Guangzhou and Hangzhou, Cat gas generator sets are used for turning landfill gas to electric power supply.

Apart from generator sets, Cat locomotive engines are used for passenger services in mainland China and cargo transportation in Taiwan. Cat marine engines are widely used in tug boats, fast ferries, passenger launches, fishing vessels and pleasure crafts in the region.
