Setting a 100 GWh Energy Storage Target by 2030: A Key Step Toward a Sustainable Energy Future

Accelerating the Energy Storage Market

A clear energy storage target is considered crucial to advancing the renewable energy transition and strengthening national energy security. Industry experts are proposing a legislative goal to achieve at least 100 gigawatt-hours (GWh) of battery storage capacity by 2030 — roughly four times the current level.

According to recent data from national energy authorities, by mid-2025 there were around 2.2 million stationary battery storage systems installed, offering a combined capacity of about 23 GWh. This rapid growth highlights the strategic role that large-scale energy storage plays in balancing supply and demand in renewable power systems.

The Growing Importance of Battery Storage Systems

Battery storage systems are essential to the future of clean energy infrastructure. They reduce the need for reserve power plants, lower grid expansion requirements, and minimize the curtailment of solar and wind generation. By stabilizing electricity prices and bridging power gaps during low production periods, energy storage enhances the reliability and affordability of renewable energy.

These advantages make energy storage capacity a central pillar in building a sustainable, flexible, and cost-effective energy system that benefits both consumers and the economy.

Removing Barriers and Strengthening Policy Support

To fully leverage the potential of energy storage in Germany, policymakers are urged to address regulatory bottlenecks and modernize the framework governing energy infrastructure development.

Industry surveys indicate that about two-thirds of companies in the battery storage sector prioritize the acceleration and simplification of the grid connection process. Other key requests include extending grid fee exemptions for storage facilities and defining clear multi-use rules that allow systems to operate with both renewable and conventional power sources.

These improvements would make it easier for project developers to bring storage projects online and contribute to national energy transition goals.

Enhancing Transparency and Project Planning

The industry supports the introduction of preliminary grid connection information to increase transparency and streamline project development. This approach enables energy storage developers to assess grid capacity before submitting formal applications, reducing time and administrative complexity.

Experts also recommend binding reservation mechanisms that allocate grid capacity based on project progress. Such measures would strengthen investment confidence and prevent grid capacity from being blocked by inactive projects.

Digitalization and Regulatory Innovation

Further progress in digitalization in the energy sector is seen as vital. Standardized timelines, automated approval systems, and penalties for delays can make grid connection processes faster and more transparent.

In addition, experts call for the quick implementation of construction privileges for large-scale battery storage systems, which are already outlined in national energy policy frameworks. These legal updates would accelerate deployment and enhance the competitiveness of the storage industry.

Building a Resilient and Sustainable Energy Future

Establishing a 100 GWh energy storage target by 2030 would not only drive technological innovation but also ensure energy reliability in an increasingly renewable-based system. By aligning energy storage policy, digital infrastructure, and regulatory support, the country can strengthen its energy system flexibility and create long-term economic value.

With coordinated action, clear targets, and strong industry engagement, large-scale energy storage can become a cornerstone of the global shift toward a sustainable energy future.
