Lower electricity costs: revolutionary memory without a solar system!

Lower electricity costs: revolutionary memory without a solar system!

The current discussion about the energy transition in Germany is increasingly focusing on the crucial role of electricity storage. Renewable electricity generation from wind and solar power is growing continuously, while fossils and atomic energy companies come under pressure to lose market shares. The abundance of renewable energies from various sources such as wind, sun, water, biomass and geothermal energy presents the energy suppliers with new challenges, especially when storing excess energy that is generated during the day and must be used at night. Öconews reports that innovative solutions such as the "Powerharvester" from 1komma5 ° EVERY to save negative prices without the need for a photovoltaic system.

The spread of such electricity storage could help to manage the challenges of (eco) electricity intermediate storage and lead to lower electricity costs for consumers in the long term. Despite the challenges that the energy transition entails, the problems remain resolved, according to many experts. BDEW emphasizes that Strom memory in Germany is indispensable Electrification in different sectors, such as mobility, heat and industrial processes, contribute.

The meaning of electricity storage

An important advantage of electricity storage is their ability to compensate for weather -related fluctuations in electricity generation and increase the security of supply. According to Section 11c of the Energy Industry Act (EnWG), the public importance of electricity storage is recognized. Nevertheless, there are legal and regulatory hurdles that brake the expansion of storage. According to the Federal Environment Agency , the proportion of renewable energies in the German gross energy consumption in 2024 rose to 22.4%, which rose to an increase of 0.8 percentage points represents the previous year.

In order to meet the requirements of the energy transition, various technologies are required. The main technologies for inpatient energy storage in Germany include pumped storage power plants that have the largest storage capacity, as well as battery stores that are becoming increasingly important. The storage capacity of all pumped storage power plants in Germany is currently around 140 GWh. In the so-called network development plan electricity of the Federal Network Agency, up to 11.7 GW pumped storage power plants, 44 GW large battery storage and 75 GW PV battery storage are sought. The prices for lithium-ion batteries from $ 649/kWh had to be reduced to only $ 152/kWh in 2023 in 2013.

A look at the numbers

The use of renewable energies in Germany provided 517 billion kWh in 2024, 55% of this energy from electricity, 38% from heat and 6% from biofuels. While biomass remains the most important renewable energy source with 47%, a increased proportion of electricity generation from wind and electrical energy is also observed. The installed wind turbine increased by 3,027 MW in 2023, and the photovoltaic systems generated 74.1 billion kWh of electricity in the same year, which corresponds to an increase of 16%.

The transport sector also shows progress: In 2024, the proportion of renewable energies was 7.2%, although the biofuel sales were reduced to 32.7 billion kWh. Renewable energies avoided around 256 million tons of CO₂ equivalents in 2024. This proves that the efforts for a sustainable energy supply in Germany are absorbed while the challenges of the energy transition are actively addressed.
