Frequently asked questions about cogeneration
Common questions about Combined Heat and Power (CHP)
White Paper
One way for businesses to control energy costs associated with heating, lighting and cooling is to employ combined heat and power (CHP) technology to extract multiple forms of usable energy from a single fuel source. This technology, also known as cogeneration, increases overall energy efficiency and is beneficial for the environment.
This paper explores frequently asked questions about CHP, such as:
Technology
- What is cogeneration or CHP?
- Is CHP a new technology?
- Which types of engines are suitable for CHP?
- What fuels can be used to power CHP?
- How common is CHP in North America?
- What does “methane number” mean?
Applications
- How much heat and power can be obtained from a reciprocating-engine-based CHP?
- What applications are suitable for CHP?
- What can the electricity and heat be used for?
- Can CHP also be used to provide cooling?
Environment
- Is CHP good for the environment?
- How does CHP reduce greenhouse gasses?
- How do CHP emissions compare to other heat sources?
Economics
- How do I evaluate my facility for CHP?
- What are the benefits of CHP?
- What does “spark spread” mean?
- Does geographic location make a difference?
Operations
- What are the physical space requirements for CHP?
- What are the maintenance requirements?
- What happens during a utility outage?
- Will I be able to disconnect from the utility?
