In respect to the expansion of renewable energies, temporary oversupplies of electrical energy cause a resulting price decline on the German electricity exchange. The electricity traded on the electricity exchange already shows high price volatility. For this reason, energy storage systems are needed that can balance energy supply and demand to ensure grid stability. The production industry can make a contribution by adjusting its consumption by shifting energy-intensive production steps to times of negative residual load.

The volatility of electricity prices is steadily increasing due to the growing expansion of renewable energies. This is particularly observable at the electricity exchange. Small and medium-sized enterprises (SMEs) in the manufacturing sector can save energy costs due to these fluctuations through targeted load management methods. To increase this potential, SMEs need to use smart meters and obtain their electricity at pricest as close to those at the electricity exchange as possible.

Due to the continuous expansion of renewable energy sources manufacturing companies are confronted with steadily rising as well as more and more volatile electricity prices. The current lack of energy storage technologies leads to a dependency on the energy supply and, consequently, to a significant increase in manufacturing costs. This article describes a new approach to planning cost-optimized production programs with the targeted use of stock levels as storage solution for in the production process employed energy.
