Battery storage

In order to counteract climate change, a large-scale conversion of our energy system towards a renewable, decentralized supply is necessary. Fluctuating generation creates a need for storage options. Battery storage systems play a key role here: they cover both the local needs of the operator and can stabilize the future power grid.

Our use cases

Multi-Use: Combine and benefit

The use of a battery storage system is not limited to individual applications. Multiple uses at the same time create synergies and significantly reduce the payback period for the investment. A combination of the different business management strategies increases your benefit and creates sustainable added value.

Be part of the energy transition: Benefit from the new electricity market

Not only the respective location can benefit from the use of a battery storage system: If using the flexibility of a battery storage system on the electricity market or as part of network services generates more revenue, these can also develop their potential beyond your own electricity meter. Mechanisms for this include, for example, intraday trading, day-ahead, spot market purchases or the provision of balancing services.

Cell chemistry LFP

Lithium iron phosphate (LFP) is used as cell technology in all of our battery storage systems. The following aspects show why we chose this cell chemistry:

Guaranteed longevity

Due to the very high cycle stability, the cells can be loaded and discharged several times a day for years

No conflict materials

LFP cell chemistry completely avoids the use of critical raw materials such as cobalt and manganese.

Life cycle assessment

Overall, the battery storage system from Allgäu Batterie is an ideal system for storing electrical energy.

Highest efficiency

Only minimal losses occur when charging and discharging the batteries.

Security

Thanks to the LFP cell chemistry, there is no risk of fire in the event of an internal short circuit in the cell.

Our answers to your questions

This is a very individual decision and depends on a variety of factors. Our experts will help you answer this question in the form of an energy potential analysis – please feel free to contact us!

In an application that is optimized for profitability, ROIs between two and ten years are usually possible. However, this depends on the framework parameters and the individual use cases as well as their clever combination.

The battery cells of our stationary battery storage systems are optimized for this use and offer both high cycle stability and low calendar aging. We assume that the cells have a lifespan of 15-25 years under normal stress. The manufacturer’s warranty guarantees the performance of the battery cells for 10 years.

Yes and no. In principle, it is possible to become 100% independent of the grid, but we design our battery storage systems assuming ideal economics. The battery storage system is not intended as seasonal storage to compensate for seasonal fluctuations.

Yes, because our storage systems are connected to the grid, the installation is independent of an existing PV system. We would be happy to clarify with you what other criteria should be taken into account when installing a battery storage system.

The components such as batteries and power electronics are almost maintenance-free, but are also subject to statutory safety tests for stationary electrical systems.
We offer optional maintenance models tailored to your needs for all of our systems, ranging from pure inspection to regular adjustments to use cases. Please feel free to contact us and we will find the right solution for you!

The funding programs offered at federal and state levels are subject to frequent changes and are usually associated with additional measures. Independent of traditional investment subsidies, there are also other options for minimizing investment costs and maximizing the revenue from intelligent use and marketing of the battery storage system. Our experts will be happy to support you with all of these topics.

By using the battery storage system for various applications, the availability of sufficient energy in the event of a power failure cannot be guaranteed. This is – among other technical challenges – the reason for our recommendation to provide an emergency power supply that is independent of the BSS only for critical consumers.
