Efficiency measures at Abbott Power Plant

Posted by Morgan White on May 31, 2013

In general, the overall efficiency of a typical power plant is approximately 35%, and the efficiency of a typical cogeneration plant is typically 80-85%.  The efficiency is in general a measure of the energy input (fuel), vs. the energy output (electricity, and in the case of a cogeneration plant steam and electricity).

We have done a lot of things to improve the plant efficiency, but at this point in time we don’t have good data available that can measure and quantify those improvements.  Some of the items that we have undertaken include:  changing out the lighting to higher efficient flourescents and/or LEDs, changing out the Centac Centrifugal Air Compressors to more efficient VFD driven rotary air compressors, changing the air compressor cooling from city water to the plant service water system, and repairing and replacing direct contact heaters.
