The large Heilbronn power plant gets pow

Efficient battery systems are required to offset power fluctuations in the electricity grid from renewable energies. Recently, this task has been taken over by a powerful power storage unit made of LIB modules at the Heilbronn power plant.

According to the Federal Ministry of Economics, renewable energies are Germany’s most important source of electricity, and their contribution to the power supply is growing steadily. However, feed-in is naturally subject to weather-related fluctuations, resulting in imbalances between generation and load. Stabilizing the power thus requires powerful storage units. Robert Bosch GmbH has developed such a power storage system for primary regulation energy together with EnBW Energie Baden-Württemberg AG in their joint venture Kraftwerksbatterie Heilbronn GmbH .

Since mid-April, it has been installed in the EnBW Heilbronn power plant, making it the first of its kind to be integrated into the control technology of a large-scale power plant in Germany. The storage unit consists of 768 lithium-ion battery modules and offers a maximum power output of around 5 MW with an installed storage capacity of 5 MWh. The amount of electricity that it can take in and deliver in exactly the right amounts corresponds approximately to the average annual electricity consumption of 400 two-person households.
