This course is intended for those that would like to gain familiarity with the various issues and challenges that are faced when considering the possibility of installing a cogeneration facility.  Cogeneration or combined heat and power (CHP) is the simultaneous production of electricity and heat from a single fuel source.  Even though the heat and power are fueled from a single source cogeneration is not a single technology, but is an integrated energy system.  It is the complexity of the system and the number of different types of entities with very different circumstances that can benefit from the choice to cogenerate that brings to light the many considerations, advantages, and possible disadvantages of installing cogeneration.   The number of options for any plant are many and the methodology is somewhat confusing, this is part of what we hope to break down though out this course.   These issues as well as economic considerations, efficiency, permitting and evaluations will be covered in the course.

What is Cogeneration?

  • Generation of heat and generation of power
  • Not a combined cycle
  • Examples of cogeneration
  • First Law of Thermodynamics – covers generation of heat
  • Second Law of Thermodynamics – covers generation of power
  • Cogeneration combines these two processes

Advantages and Disadvantages of Cogeneration

  • Cogeneration is more efficient that generating each separately
  • Reduces dependence on the grid
  • Allows for “islanding”
  • Provides for power when the grid is down
  • Cogeneration is more complex
  • Requires a balance between thermal load and electrical load
  • Implies the need for more redundancy to “island”
  • Is not that much more efficient
  • Can be costly


  • What do we mean by efficiency?
    • Combustion efficiency
    • Boiler efficiency
    • Cycle efficiency
    • Gross and net plant heat rate
    • Cogeneration efficiency
    • Marginal heat rate
  • Pitfalls
    • HHV
    • Mixing up first law and second law comparisons
    • Example

Types of Cogeneration Plants

  • Boiler with back pressure steam turbine
  • Gas turbine with HRSG (with supplementary firing)
  • CFB with external heat exchanger
  • Trigeneration

Plant Considerations

  • Steam load and its variations
  • Electric load and its variations
  • Reliability
  • Back-up power
  • Plant needs
    • Manufacturing
    • Chemical plant
    • Refinery
    • Hospital
    • University
  • Hypothetical plant


  • Who owns the plant?
    • Industrial (balance sheet financing)
    • IPP (or 3rd party)
    • Municipal
    • Hospital
    • University
  • Cost of money
  • Plant size
  • Critical requirements
  • Self-generation vs sell to the grid

Permitting and Environmental Issues

  • New unit
  • Retrofit
