Combined Heat and Power

Combined Heat and Power (CHP) high efficiency equipment can help save your facility considerable money on energy bills each month.

How Combined Heat and Power (CHP) Works

Natural gas-fired CHP systems - sometimes called cogeneration - generate electricity while the waste heat produces steam or hot water.

Instead of separately purchasing electricity from the power grid and then burning fuel in a boiler to produce thermal energy, CHP gives you both in one highly-efficient package.

This provides a hedge against electricity cost increases while also protecting your business from electric service interruptions.

With typical payback times of three to five years and equipment that lasts up to 15 years, the savings and benefits really add up.

Benefits of a CHP system include:

  • Up to 40 percent energy savings
  • Increased reliability and resilience with no disruptions to your operations
  • Total efficiency of up to 75 percent

CHP systems can also be assembled and be modified to meet your facility's specific energy needs. Components include a prime mover, generator, heat recovery exchanger and electrical interconnection. Prime movers may be reciprocating engines, combustion turbines, steam turbines, microturbines and fuel cells.

In October 2018, Eversource held a forum featuring a panel of customers who installed cogeneration. Hear what the panelists had to say about researching cogeneration before getting ready to install cogeneration.

No heat load? Distributed generation might still make sense

If your operation can’t effectively use the waste heat from a CHP system, generating your own electricity with a Distributed Generation (DG) system can still provide significant energy savings and resiliency benefits.

DG is similar technology to CHP, but the waste heat is vented instead of captured. Multiple DG technologies can be used for generating power, including natural gas-fired reciprocating engines, full size turbines, microturbines, and fuel cells.
