There are many applications for electric storage systems in manufacturing systems. Applications for maintaining production in case of a blackout are already established and economical, but applications for optimizing energy supply are becoming increasingly interesting for manufacturing companies. Peak shaving is one application for optimizing energy supply, which has the potential to reduce gird charge of industrial consumers. The grid charge for industrial consumers depend on characteristics of their energy consumption. The smoother power is drawn from the grid, the less grid charge has to be paid. This goal can be achieved by integrating an electric storage system for peak shaving. Electric storage systems offer high power and capacity, making them the ideal solution for this application. The challenge is the sizing of the electric storage system and the resulting economic efficiency. In this article a sizing methodology for electric storage systems, aiming for industrial grid charge reduction, is presented.
