Efficiency Improvements to Reduce GHG Emissions
The overall efficiency of a power plant encompasses the efficiency of the various components of
a particular generating unit. Sometimes these systems are unique to a generating unit, while in
other instances these systems may be shared between generating units at a power plant site. This
section will summarize the results of several U.S. and international studies which present options
for improvements to power plant systems capable of increasing system heat rate efficiency and
reducing GHG emissions. While the focus of this report is improving the efficiency of U.S. coalfired
power plants, studies from the international community are also presented as suggested
improvements apply generally to coal-fired power plants. Further, a key report from an AsiaPacific
Economic Cooperation (APEC) working group report laid the groundwork for several U.S
and international studies.
