Presentation 3.2: Demand side energy management Frank Taelman Energy & Maintenance Manager Siemens E-mail: [email protected]Abstract With Demand Side Energy Management Siemens Industrial Services has created a package of services to provide sustained improvement in the energy efficiency of a production facility while reducing energy consumption. The profitability of a production facility also relies on an inexpensive and reliable supply of power, heating, cooling, and compressed air. The provision of energy, is no more than just a secondary process outside the core competence. Most of all, however, it's a cost factor. Aim is to use energy much smarter, thus increasing productivity. Demand Side Energy Management from Siemens Industrial Services takes a detailed look at the technical and economic aspects of the entire process. This enables us to develop a step-by-step concept to improve energy efficiency in line with the business needs – and then to implement it. 265
