The global energy storage market is entering a new stage of rapid growth. Europe has surpassed 100 GWh of battery storage capacity,

Germany continues to expand solar deployment, and the UK is experiencing one of the fastest battery storage growth rates in the region.

As renewable energy penetration increases, battery energy storage systems (BESS) are becoming an essential part of modern energy infrastructure.

This is creating growing demand not only for standardized batteries, but also for custom energy storage solutions, OEM/ODM battery systems and professional energy storage system manufacturers

that can adapt products to different markets and applications.

For distributors, installers, system integrators, energy companies and emerging energy brands, choosing the right energy storage OEM/ODM manufacturer is becoming increasingly important.

Europe’s Energy Storage Market Surpasses 100 GWh

Europe's battery storage market continues to expand rapidly, driven by solar PV deployment, grid flexibility requirements and the increasing need for energy independence.

Approximately 36 GWh of new battery storage capacity was installed in Europe in 2025, bringing total operational capacity above 100 GWh.

Germany, the UK and Italy remain among Europe's leading markets, while Central and Eastern European countries are also becoming increasingly attractive for battery energy storage projects.

This growth is driving demand across multiple applications, including:

Residential energy storage systems

Commercial and industrial energy storage

Utility-scale BESS

Solar-plus-storage systems

AC-coupled battery storage

Retrofit energy storage systems

Customized battery energy storage systems

For international buyers, the opportunity is moving beyond purchasing individual batteries toward sourcing complete energy storage system solutions from experienced manufacturers.

Germany’s Solar Growth Creates New Opportunities for Battery Storage

Germany's latest ground-mounted solar auction further demonstrates the strength of the European renewable energy market.

As solar capacity continues to grow, the ability to store excess electricity becomes increasingly important. Battery storage can help increase solar self-consumption, reduce peak electricity costs and improve energy resilience.

This creates strong opportunities for solar battery storage manufacturers and energy storage system solution providers capable of supporting different system architectures.

For installers and system integrators, flexible solutions such as AC-coupled energy storage systems can also provide an effective option for upgrading existing solar installations with battery storage.

The UK Is Becoming a Key Market for BESS

The UK installed approximately 5.2 GWh of new battery storage capacity in 2025, representing 64% year-on-year growth.

The rapid development of both grid-scale and distributed energy storage is creating opportunities for battery manufacturers, distributors and system integrators.

For companies entering the UK market, working with an experienced energy storage OEM/ODM manufacturer can provide greater flexibility in product configuration, branding and system design.

Instead of relying exclusively on standardized products, B2B customers can develop custom battery energy storage systems designed around their target applications, installation environments and market requirements.

Why OEM/ODM Is Becoming More Important in Energy Storage

As the global BESS market becomes increasingly competitive, energy companies and distributors are looking for more than off-the-shelf batteries.

Different markets have different requirements for:

Battery capacity

Voltage configuration

Communication protocols

Inverter compatibility

Mechanical design

Installation method

Safety systems

Monitoring platforms

Branding

Certifications

This is where energy storage OEM/ODM services become particularly valuable.

An experienced OEM/ODM manufacturer can provide customized battery packs, system configurations, enclosure designs, BMS integration and branded products according to customer specifications.

For distributors and energy brands, OEM/ODM cooperation can shorten product development cycles while allowing them to build differentiated energy storage products under their own brands.
