Energy exchange

In a classic example of self-sufficiency, Caterpillar subsidiary Solar Turbines has supplied three natural gas powered Titan 130 combustion turbines to the AES Medina Valley a cogeneration plant which supplies power to Caterpillar plants in Peoria. The turbines drive three generators, each producing 12.2MW of electricity. Turbine exhaust is converted in steam generators for heating and manufacturing in winter and in summer run through absorption chillers to provide chilled water to cool the building.

The Medina Valley plant currently supplies electricity, steam heat and chilled water to Caterpillar's Mossville campus and electricity to the Mapleton foundry.
