Combined Heat and Power/Cogeneration

Combined heat and power (CHP), also known as cogeneration, is the simultaneous production of electricity and heat from a single fuel source, such as: natural gas, biomass, biogas, coal, waste heat, or oil. Cogeneration is not a single technology, but an integrated energy system that can be modified depending upon the needs of the energy end user.


CHP provides:

  • Onsite generation of electrical and/or mechanical power
  • Waste-heat recovery for heating, cooling, dehumidification, or process applications
  • Seamless system integration for a variety of technologies, thermal applications, and fuel types into existing building infrastructure
  • The two most common Combined heat and power system configurations are: Gas turbine or engine with heat recovery unit and Steam boiler with steam turbine

Distributed Generation

ESG helps customers generate heat or electrical power to operate their plants, sending the surplus electrical power back into the power grid or sharing excess heat via a distributed heating grid.


Natural Gas


Renewable Power




Decentralizing central heat plants can help reduce energy costs by eliminating distribution pipe heat losses and inefficient heat exchangers, and enhancing plant security, resiliency, and infrastructure capabilities.
