Can cogeneration and/or waste heat recovery be considered a  source of
renewable energy?

The Tompkins Renewable Energy Education  Alliance (TREEA) will host a
presentation on the new combined heat and power  addition at Cornell
University by Lanny Joyce and Ed Wilson, managers in the  Utilities and
Energy Management department at Cornell.

Cornell’s  central heating plant (CHP) first came online in 1922 producing
steam from  Pennsylvania anthracite coal. The plant relies on low sulfur
bituminous coal  as a primary fuel, supplemented with either natural gas or
oil when needed.  Currently, Cornell buys about 85 percent of its
electricity from the grid  through New York State Electric and Gas (NYSEG).
Of the remaining 15 percent,  13 percent is a product of cogeneration.  The
other 2% is from the  university hydroplant on Fall Creek.   Soon, however,
the majority  of Cornell’s electricity is expected to come from  internal
sources.

Cogeneration produces heat and electricity from one  fuel. In a
conventional power plant, a boiler produces high-pressure steam  that is
used to drive a turbine, which in turn drives a generator to  produce
electricity. The exhaust steam is generally condensed to water, which  goes
back to the boiler and the heat released in condensation is  wasted.
Cornell's current cogeneration, built in 1986, extracts energy from  steam
and transforms it into electricity.  Before the steam is sent to  the
campus, it is passed through two steam turbines to produce  electricity.
This cuts down (by about 50%) the amount of energy wasted as  heat to the
environment by meeting these needs separately.  Combined  heat and power
can cost-effectively reduce environmental impacts associated  with  energy
use.
