Electric and Thermal Tracking
188.8.131.52 Electric Tracking. Electric tracking is defined as the continuous generation
of electricity to meet the electrical demands of a facility as they occur throughout
the daily load swings. With electric tracking, cogeneration equipment is used to
generate as much steam as the electric load will allow with supplemental steam demands
generated directly by use of boilers. The use of automatic extraction condensing
turbine generators and combined cycles also provides the means for electric tracking.
184.108.40.206 Thermal Tracking. Thermal tracking is defined as the continuous generation of
heat or steam to meet the thermal demands of a facility as they occur throughout the
daily load swings. With thermal tracking, cogeneration equipment is used to generate as
much electricity as the steam load will allow with supplemental electrical demands
generated on other equipment such as gas turbine generators, diesel generators, and
steam turbine generators. Automatic extraction condensing turbine generators and
combined cycles provide the means for simultaneous tracking of both electric and thermal
Interconnection with Utility
interconnected with an electric utility are conditions of either the electric utility
rate schedule for parallel generation contract service or separate contract of agreement
between the cogenerator and utility. The conditions as set out in the contract may be
site specific and cogeneration system specific. Typical examples are as follows:
delivered to the utility system shall be maintained within specified limits.
b) The utility may reserve the right to limit the amount of electrical
load delivered to the utility system at certain times and as utility electric operating
c) The utility may reserve the right to inspection, observation of
testing, and specification of certain maintenance requirements.
d) The cogenerator may be required to notify the utility prior to
initial energizing and startup testing of the cogeneration facility.
