Combined Heat and Power - What is it? Combined Heat and Power (CHP), or cogeneration, is the simultaneous generation of
electrical or mechanical power and useful thermal energy from a single fuel source.
•Utilize the heat that would have been wasted as steam, hot water, or cold water.
•CHP is not a single technology but an approach to applying various technologies.

Combined Heat and Power Why? - Increased Efficiency and Cost Savings
CHP can:
Increase energy efficiency
Reduce site energy costs
Reduce air pollutant emissions
Enhance site energy reliability
Provide critical power stability
Reduce transmission cost
Delay need for new T&D
infrastructure
Use clean domestic energy
sources (natural gas, biomass,
and biogas)

Combined Heat and Power Does your site qualify?
CHP is an economic decision and must be evaluated on a case by case basis.
What is the prime objective? Electric or Thermal Heat Demand
Qualifiers:
Extended operating hours (greater than 5,000 hours)
High electric and/or thermal demand
Need to meet standards for energy efficiency (corporate, state or federal)
Environmental Regulation pressure (GHG emissions, Boiler MACT)
Large Spark Spread – Cost of generating power VS. buying from the grid
Replacing or expanding existing steam/heat generator offset
Energy reliability and/or critical power stability offset
Rule of Thumb:
CHP usually makes economic sense if greater than 50% of available thermal
energy can be used on an annual basis.
