1. Energy Management System at AD ELEM REK Bitola

2. Dedication
“Aware of the fact that the Energy Production sector, is also a serious energy consumer, we recognize the need for raising awareness and changing the attitude towards a more responsible energy consumption. Therefore, as a corporate socially responsible company, we feel the obligation to show leadership in the rational use and management of energy resources, with which we represent an example to our consumers“
Excerpt from the Energy Policy of AD ELEM 2
