Before the implementation of M&T measures some preparatory steps are needed as described below:

a) Identification of the major energy consumers in each sub-process. Usually, the primary energy consumption is due to a small number of devices or in processes or machines (Paretto rule). Usually, this step requires a site visit to survey the equipment and systems, and some measurements of the level of consumption of the various equipment.

b) During this step of the M&T program, it is necessary to define other process variables that can help to characterize it, such as production, temperatures and flow rates. Once the variables are defined and the necessary measuring equipment is installed the remaining steps of the M&T program can be initiated.
