Residential Energy Storage Reaches 200,000 in Germany: What Can We Know?

Germany is the largest market for home storage solutions in Europe, with a rising number of installations thanks to encouraging policy requirements. 2022 is expected to see no change in the upward trend in the German market for residential solar storage systems. According to the EuPD research, the number of residential energy storage systems in Germany will reach 200,000 by the end of 2022.[1]

Why Do People Choose Residential Energy Storage in Germany?

Energy storage is a key node for the entire grid, enhancing resources like demand-side resources, system efficiency assets, wind, solar, hydropower, and nuclear and fossil energy. It can sometimes function as a generation, transmission, or distribution asset all in one.


In short, Germans have been utilizing residential energy storage solutions to help them save money, integrate their generation sources, and reduce their environmental impact.


1. Lower Bill Cost

A home energy solution helps people save money on electric bills by reducing reliance on the grid. Additionally, it protects them from changing energy costs by choosing to use the stored energy only during periods of high demand, when prices are at their highest. Germans, for instance, tend to use stored energy during the afternoons and evenings of the weekdays when energy prices are typically at their highest.

2. Facilitates Effective Utilization of Renewable Sources

Resources like wind and solar that are intermittent or variable in supply can be effectively utilized by energy storage. The system does this by storing excess energy when the wind blows and the sun is out and releasing it when the opposite is true. When demand fluctuates rapidly and flexibility is required, residential energy storage can cut in or retrieve electricity as needed to precisely match the load.

3. Reduces the Need for Increased Peak Generation Capacity

Electricity usage is constantly on the rise, and with the need for increased peak generation capacity. Increased peak generation capacity is the additional energy that a power plant can produce when it is needed most. It allows for more electricity to be generated during times of high demand, such as heat waves or cold snaps. This extra capacity helps maintain reliable service and avoids rolling blackouts, which occur when there is not enough supply to meet the demand. Increased peak generation capacity can be achieved in a variety of ways, such as increasing the size of existing generators, adding additional generators to an existing grid, or using renewable energy sources. This has placed a strain on our current resources.

Storage can help to smooth out the peaks and valleys in energy production, making the grid more stable and reducing the need for expensive peak generation capacity. This can reduce overall energy costs and create a more reliable, sustainable grid.

4. Enhances Grid Reliability

The lithium-ion battery, the key element of energy storage systems, is a great investment for the future. It improves grid reliability and power systems by providing instant backup power. As a quicker and frequently less expensive alternative to building new distribution and transmission power lines, it also reduces the need to build fresh, expensive power plants and helps relieve grid congestion.

Issues to Consider Before Investing in the Energy Storage Sector in Germany

Although the transition to energy storage is well underway in most of Germany’s residential areas, some energy storage challenges need to be considered by those looking to invest in the energy storage industry.


Energy Law and Regulation

In terms of energy law and regulation, the residential energy storage field is known for lacking a uniform legal framework. In Germany, residential electricity storage was classified using the common roles found in the energy market, and since no distinct definition existed, it was given a dual role.

This dual function resulted in the EEG surcharge, CHP surcharge, and offshore liability surcharge being applied twice to electricity storage facilities. However, through the netting law in section 61 l of the Renewable Energy Act of 2017, lawmakers have partially attempted to avoid this double charging.

Environmental and Planning Law

When requesting approval for projects that affect the environment, there are strict requirements under Germany’s substantive law.

The requirement for an environmental impact assessment, national and European legislation on the protection of nature and species, and water law are all potential issues in this context, particularly when it comes to large-scale storage facilities like pumped storage power plants and large battery storage systems.

Team Up With a Reliable Battery Supplier

High-quality battery storage systems are becoming increasingly important for responding to electricity demand and supplying green energy. This is where lithium-ion battery comes in.

The intermittent problems associated with renewable energy have been resolved by lithium batteries, giving electric vehicles an efficient method of storing a significant amount of energy. In short, one must work with a trustworthy home solar battery storage supplier since it is one of the main components of residential energy storage.
