Overview

1061 - 1515 kW Gas Generator

The CHP1500 is an enclosure standardized for natural gas-fueled Cat® G3512H engines rated 1.5 MW, with generator rated for 4160V for combined heat and power (CHP) applications. In CHP applications, Cat gas generator sets simultaneously provide electricity for electrical loads and heat energy for a facility's thermal requirements. Caterpillar will offer customers complete CHP solutions eliminating the need to outsource additional engineering or project management.
