Cogeneration

Current Research

Current cogeneration research is examining ways of improving the old technology. One improvement involves steam-injected gas turbines, which would increase the electric output capacity of the turbines, and thereby increase the energy efficiency of cogeneration. Other improvements are making cogeneration more feasible for smaller plants. Currently, this technology is feasible only in larger facilities. Smaller cogeneration units would allow a more widespread application of this energy efficient technology.

Avoided cost

—Under PURPA, this is the price that the utility company must pay to buy electricity from a cogenerating company. It is calculated as the amount the utility would have paid if the utility company had generated the electricity itself.

Public Utilities Regulatory Policies Act (PURPA)

—This is U. S. federal legislation that is designed to encourage the development of cogenerating plants.

Waste heat

—This is heat that is released as fuels are burned but is not used.
