Online event "Battery Storage System (BASS) in commercial use"

The online event “Battery Storage System (BASS) in commercial uses” took place on 24 September 2024 with around 50 participants as part of the event series “Energiewende aktuell” (“Energy Transition Today”).

Key takeaways

Hans Urban from the engineering office “Fachberatung Erneuerbare Energien und E-Mobilität” discussed the various possible uses of electricity storage systems, both in the private and commercial sectors and as a grid booster.

According to Mr Urban, electricity storage systems are primarily used in the private sector to optimise self-consumption and achieve self-sufficiency. For commercial use, several options and simulations were presented during the event, along with their profitability analyses. The amortisation period depends heavily on the development of electricity prices. Here too, Mr Urban recommends electricity storage systems to optimise self-consumption.

Three possible fields of action were mentioned for storage in the grid. Firstly, participation in so-called innovation tenders, in which storage systems can receive funding in connection with PV systems. Secondly, electricity storage systems can be used as grid boosters. These are awarded by the Federal Network Agency and are intended to contribute to the stability of the electricity grid. However, there are only a few tenders, and the market is difficult to develop. In addition to these two options, the free marketing of stored electricity via the electricity market is also an option. Good financing options ensure a quick amortisation period.

In conclusion, Mr. Urban emphasizes that the combined use of storage systems in different application cases is important for their economic efficiency.
