A cogeneration plant is one that:

  1. Produces both electric power and useful process heat from the same energy source
  2. Uses two different fuels
  3. Uses two turbines in series
  4. Generates power using only renewable energy

Answer

A. Produces both electric power and useful process heat from the same energy source

Solution

Cogeneration (combined heat and power) uses heat that would otherwise be rejected, raising the overall utilization factor.
