Combined heat and power (CHP) plants, also known as cogeneration plants,
generate useful heat at the same time as generating electricity. Cogeneration
makes more efficient use of fuel, putting the heat energy that would otherwise
be a waste product of electricity generation to good use.

Recovering Thermal
Energy
CHP plants are designed to re-
cover the thermal energy that
would otherwise be wasted
and convert it into useful heat.
Steam- or gas-powered tur-
bines are driven by a supply
of high-energy heat to create
electricity, in a process that
also produces low-tempera-
ture heat. Rather than wast-
ing this, CHP plants then use
the low-temperature heat for
space heating or water heat-
ing. Cogeneration was actually
practiced in many larger build-
ings prior to the advent of utili-
ty electricity from central pow-
er stations.
Trigeneration
Trigenerationinvolvesasimilar
process but uses a solar heat
collector or combustion of fuel
to generate useful cooling, as
well as heat and electricity.
Typically, trigeneration uses an
absorption refrigerator so that
the waste heat can be used for
cooling as well as heating.
A new CHP plant is
planned as part of
the construction
of a new grain
terminal at the
port of Zarubino.
