Stationary Battery Storage – Stability and Flexibility in the Energy System

Climate protection issues and solutions for the future energy system are becoming increasingly important. It is undisputed that storage solutions for renewable energy are essential for the transformation of our energy system, especially with respect to the increasing sectoral integration of the electricity, heat, transport and industry sectors. Further R&D activities as well as targeted and far-reaching political and regulatory measures are absolutely necessary for a sustainable and economically viable dissemination of battery storage systems.

Home storage systems as smaller, decentralized battery storage systems have long been state-of-the-art in homes and serve there as intermediate storage for PV electricity generated on the roof of the house. Larger-scale district storage systems, used as intermediate storage in housing estates and residential areas, enable the shared use of locally generated electricity. There is enormous potential in the strong expansion of stationary large-scale battery storage, especially in conjunction with photovoltaic power plants. On the one hand, these can partially compensate for the shutdown of nuclear and coal-fired power plants and also offer a climate-friendly perspective for former power plant sites.

Falling electricity generation costs for renewable energies and a downward trend in battery prices on the one hand, and sharply rising energy costs and growing uncertainty in the established energy markets on the other, are making Commercial & Industrial (C&I) storage increasingly interesting for use in industry, services and commerce. Companies can use self-generated PV power to make themselves less dependent on volatile energy prices, ensure a reliable energy supply, and additionally contribute to CO2 savings.
