[November 6, 2025, Munich, Germany] As Europe accelerates its green energy transition and digital transition, building a sustainable, stable, and intelligent energy system has become an imperative. Against this backdrop, co-organized by Huawei Digital Power, BVES and Osborne Clarke successfully convened its inaugural Energy Storage Summit Europe 2025 from November 5-6 under the theme "Powering Stability, Boosting Revenue".
Bringing together over 500 representatives, business leaders, and ecosystem partners from across the region, the summit delved into critical pathways for Europe's energy evolution. Key discussions centered on regional energy interconnection strategies, accelerating the clean energy transition, unlocking sustainable investment and financing, and driving large-scale technology implementation. Huawei Digital Power Europe took center stage, unveiling its comprehensive portfolio of high-quality, all-scenario Smart String Grid-forming Energy Storage Solutions alongside the innovations. The event fostered deep, collaborative dialogues with customers and partners, reinforcing Huawei's active contribution to powering Europe's journey towards a zero-carbon society.

Zhou Jianjun, Vice President of Huawei and President of Global Marketing, Sales and Services of Huawei Digital Power, delivered a welcome speech at the summit. He stated that “Huawei put safety and reliability as No.1 priority factor. We focus on high quality and have built an end-to-end safety and quality assurance systems. Our quality control system starts from quality of design, quality of supply and procurement, quality of manufacturing, quality of services.”
Steve Zheng, President of Smart ESS, Huawei Digital Power
Steve Zheng, President of Smart ESS, Huawei Digital Power, delivered a keynote speech on “Huawei Grid-Forming BESS Solution Advantages and How to Improve Customers’ Revenue”.
He noted “For lifecycle higher benefits, the unique package-level and rack-level optimizers, higher-precision BMIC components, dual-stage architecture, and other hardware technologies, combined with advanced RTE and high-precision SOC software algorithms, deliver higher lifecycle benefits to the customers.”
The industry trends emerging from the event were clear and powerful. As renewable energy penetration increases, so do the challenges of maintaining grid stability — highlighting the growing value of flexibility assets such as battery energy storage systems (BESS). As Beatrice Schulz, Head of Markets and Technology at BVES, noted, that many countries are investing heavily in battery energy storage to stabilize their grids and integrate more renewables.
Equally promising, countries such as Germany are now procuring stability services through market-based mechanisms. Wilhelm Kiewitt, Head of Energy Economics at 50Hertz, emphasized that BESS shall play a key role in the provision of ancillary services in the future electricity system. Inertia, reactive power, and black start capability create new market opportunities for BESS, while balancing reserve is already well established. Such developments clearly open up new revenue streams for BESS.
With multiple revenue streams stacking, BESS business models are becoming increasingly mature. Although ancillary service markets may face saturation risks over time, price volatility in day-ahead and intraday markets is driving stronger arbitrage potential. Germany, as Europe’s largest electricity market, is a strong example. Zach Williams, Market Analyst at Modo Energy, observed that ancillary service markets are starting to show signs of saturation from 2027 onward. Considering strong demand growth, we don’t expect to see arbitrage volumes saturating until after 2040.
As a result, trading optimization strategies are becoming more complex, requiring greater operational flexibility. Jürgen Pfalzer, Chief Growth Officer at Enspired, highlighted that a good battery system must offer flexibility in its performance warranty — allowing optimizers the operational freedom to maximize commercial outcomes for clients.
On the contractual side, tolling structures are drawing increasing attention. Anna von Bremen, Partner and Head of Energy Innovation at Osborne Clarke, introduced the concept of tolling agreements in detail. While only a few cases exist in the market today, BVES and Osborne Clarke are jointly working toward standardization — an encouraging step that will help build investor confidence and accelerate the maturation of commercial models.
Building on these market dynamics, from a product perspective, BESS is not merely a commercial asset delivering investment returns; it has become a critical resource for grid stability. A battery energy storage system is not just a product — it is a complex system. From both a long-term investment and system reliability standpoint, the market demands technically robust, high-performance, GFM-capable, and flexibly operated solutions.
On November 6, 2025, over 500 attendees participated in visits to two PV+ESS project sites in Germany. The first stop featured a 120 MW PV + 62 MWh battery project operated by HDG Technik GmbH, demonstrating how reliable, grid-connected clean energy can help stabilize power supply and reduce emissions. The facility includes 500 × 330KTL inverters, Jupiter-6000K-H1 STS, and 14 × 4.5 MWh BESS units configured with low-voltage AC coupling. The second visit to the Vispiron site at O₂ Surftown MUC showcased a 120 MW PV + 14 MWh system integrated with EV charging and operated under a prosumer model, highlighting how businesses can both consume and contribute renewable energy to the grid. Together, the two sites offered valuable insights into large-scale PV+ESS integration and emerging best practices in the European energy transition.
