An accurate measurement of retrofitted loads is essential for the quantification of energy
savings in an energy conservation measure project. This research presents an optimal meter
placement approach to an ECM project in a ferrochrome plant. The ECM project is implemented
in a selected plant in a ferrochrome production line in which three different types of
loads are considered for retrofitting.
The aim of this research is to minimize the metering costs associated with the measurement
and verification process while satisfying the precision and accuracy requirements for
the sampling and measurement plan. The metering costs are reduced by using two types
of metering devices. One meter yields highly accurate data measurements, has superior
functionality to the other meter and is consequently highly priced. Different sampling requirements
for the ECM project are evaluated and an optimal solution is found by selecting a
combination of inexpensive and expensive metering equipment. The proposed optimal meter
placement configuration yields a combination of meters with the highest accuracy in the ECM
and has the lowest cost.
