As part of an enterprise-wide energy management plan, Evonik Industries AG has developed and implemented innovative energy efficiency measures, for example the stepwise optimization of a thermal post-combustion plant.

The so-called “Efficient Energy Management (EEM)” plan was established in the company with the aim of constantly improving the efficiency of energy usage. The experience gained in individual departments and locations is then utilized over the entire company. To provide cost and emission reductions, the aim is to ensure that every production site should use energy as efficiently as possible according to state-of-the-art energy efficiency measures.

For initial determination of the potential savings, an internally developed “EEM Quick Check” questionnaire was used as a starting point to provide indications of possible optimization potentials based on previous experience. These results were then used to form interdisciplinary teams of experts who analyse all energy generation, distribution and usage processes and develop energy savings proposals.

Up to the present day, 26 of the 109 chemistry production sites of Evonik have been examined and potential savings ranging from 4 to 25 percent of the annual energy costs have been discovered. About 250 optimization measures have been developed up to now and 90 of these have already been implemented.

Assessment.
Evonik has developed a company-wide comprehensive energy management plan. It is used operationally at 26 sites, which has given the plan a great deal of leverage. Among other outstanding features, the use of cross-departmental teams of experts and the integration of the site employees, allowing them to make their own optimization suggestions, are exemplary aspects of the plan. The energy management plan developed by Evonik can be used as a model by other industrial concerns wishing to systematically implement energy efficiency improvements across all their production sites. The international presence of the company allows this expertise to be transferred to other countries to achieve similar improvements.
