Combined Heating & Power Technology

CHP is the sequential production of two forms of useful energy — typically electricity and heat — from a single fuel source. CHP offers extraordinary benefits in terms of energy efficiency and emissions reductions by optimizing the use of heat that would otherwise be wasted when generating power. CHP systems can improve power quality, reliability, and overall energy security.

ORNL offers CHP feasibility screenings and technical assistance with CHP technologies.

RCIEE’s CHP experts support DOE as FEMP’s CHP Core Team, helping FEMP’s customers with the technology.

The ORNL CHP team’s expertise covers:

  • CHP power generation technologies — turbines, internal combustion engines, microturbines, steam turbines, fuel cells
  • CHP waste-heat-activated technologies – generation of hot water and steam, absorption cooling, desiccant dehumidification
  • Feasibility issues — emissions, interconnection, cost and performance benchmarking

Free Initial Screenings for CHP Feasibility

To request an estimate of CHP economics at your federal site:

  • Download FEMP's data entry form.
  • Fill in the requested information (requires only minimal input from facility managers).
  • Be sure to indicate to whom the resulting analysis and report should be sent.
  • Submit the form via email or fax.

This initial screening helps determine whether more detailed analysis for CHP potential at your facility is worth the effort. Analysis is recommended for facilities having significant thermal power needs and more than 1 MW of average electric demand.

Example Screening Reports

The CHP team also offers the following technical assistance services to federal agencies and others

  • Detailed performance analysis of proposed systems based on TRNSYS
  • CHP system application economic evaluations
  • Utility service rate evaluations
  • Initial feasibility screening using the Buildings Combined Heat and Power (BCHP) Screening Tool
