Improved energy efficiency (EE) is recognized as an essential strategy in energy and climate change mitigation policies (IPCC, 2014). Greater competition, unpredictable energy markets and control on greenhouse gas emissions, drives manufacturing industries to manage their energy demand carefully and use it efficiently. Energy management (EnM) as a cost reduction and risk protection strategy against the unpredictable energy market is a robust tool and support function which helps industries to improve their EE level. However, since energy cost in comparison with total production costs in manufacturing companies has the small portion consequently it receives little attention.
