There is shortage of trained staff within SMEs and even large enterprises that can
be dedicated to energy auditing, efficiency/ optimisation and overall energy management
in manufacturing. A key gap is the provision of a capability to automatically monitor
energy consumption data in production manufacturing and the analysis of the data to
permit optimising the minimisation of energy. This paper outlines a methodology for
effective monitoring of total energy consumption during the manufacturing process,
so as to reduce overall energy costs. A case study is presented on the application
of the methodology in quantifying the levels of direct auxiliary energy used in a
real-world manufacturing company. The outcome of the study highlights the significance
of auxiliary energy on total energy usage.
