As energy storage holds a key role in supporting the grid and energy transition efforts, Sungrow’s ESS Experience Day in Munich was an insightful opportunity for leading experts across Europe to exchange thoughts on this crucial topic towards a sustainable future. The event was followed by almost 300 attendees. It covered a broad range of topics, relevant to the technological, business and safety implications of energy storage systems.

Reconfirming its commitment to supporting its partners and driving the transition to a clean and sustainable future, Sungrow successfully hosted the ESS Experience Day in Munich on March 20, bringing together industry experts, partners, and stakeholders to explore the latest advancements in energy storage systems (ESS).

The event underscored Sungrow’s devotion to driving the transition towards a more resilient, stable, and renewable-powered energy landscape across Europe.

Energy Storage: A Cornerstone for Europe’s Renewable Future

As Europe accelerates its shift to renewable energy, the need for grid stability and flexibility has never been greater. Energy storage systems play a critical role in balancing supply and demand, enabling a higher penetration of renewables into the grid. By 2030, Europe aims to generate at least 45% of its energy from renewable sources, according to the European Commission’s REPowerEU plan.

However, intermittent generation from solar and wind requires advanced storage solutions to maintain grid stability and prevent curtailment. The deployment of ESS projects requires advanced technologies, but also strong collaboration between involved parties and devoted teams of experts that secure swift and efficient operations, Mr. Shawn Shi, Vice President of Sungrow and President of Sungrow Europe, emphasized in his speech that opened the event.

“The outstanding result that made possible the commercial operation of the BW ESS Bramley 331 MWh project in just 12 days after the grid energization, reflects not only the technical innovation of PowerTitan 2.0; it is also a reflection of our excellent delivery management capabilities and close collaboration with our partners,” he asserted.

An evening full of insights and meaningful discussions

The event in Munich acted as a platform to exchange in-depth knowledge and thoughts by experts in the industry, including case studies, while the almost 300 attendees had the opportunity to experience hands-on demonstrations of Sungrow’s latest state-of-the-art battery storage systems: the liquid-cooled PowerStack 200CS and PowerTitan 2.0.

One of the highlights of the event was the presentation Policies & Trends of Battery Storage by Mr. Antonio Arruebo, Market Analyst at SolarPower Europe (SPE). It included an exclusive preview of preliminary figures from the SPE Battery Outlook, the leading report about the current and future development of the field. It will be officially published at Intersolar in May 2025.

PowerStack 200CS and PowerTitan 2.0 are Sungrow’s latest state-of-the-art battery storage systems

Mr. Arruebo underlined the need for flexibility of the grid, predicting that EU power flexibility needs to increase fivefold by 2030 and arguing that batteries and demand response can meet two thirds of flexibility requirements.

At the same time, the forecast is that the European BESS market is expected to expand by 30% to 40% year on year to reach 260 GWh by 2028. The high scenario by SPE foresees that this figure could reach 400 GWh by the same year.

Two milestone European projects were showcased at ESS Experience Day

The agenda of the event covered a broad range of issues related to ESS and energy transition. It included the latest developments on grid forming capabilities, presented by Dr. Ivan Volodin, ESS Product Manager at Sungrow Europe, and the impressive PowerTitan 2.0 large-scale burn test, presented by Mr. Yang Ye, Senior Technical Marketing Manager at Sungrow OSKA, showcasing the latest developments on BESS safety.

Flexibility is a key factor for deploying more renewable energy and fighting negative prices and price volatility.

Moreover, Mr. Andres Doebel, Head of ESS for the DACH region at Sungrow Europe, emphasized in his speech the crucial aspect of the one-brand solution in securing a successful ESS project. Mr. Robert Von Wahl, Director of Sungrow EV Charging Europe, analysed the opportunities that ESS holds for the crucial role of electric vehicle (EV) charging infrastructure and operation in Europe.

Signal Iduna Park, the home of Borussia Dortmund Football Club, is set to become the site of the world’s largest solar power plant installed on a stadium roof.

PV module manufacturer JA Solar, based in China, and German football club Borussia Dortmund are joining forces for the installation of a new photovoltaic system on the roof of Signal Iduna Park, creating the world’s largest PV system on a stadium roof, according to JA Solar.

The stadium, which hosts the highest average number of spectators per match in European football, has also become a flagship of sustainable innovation.

Of note, the 4.2 MW solar power plant that Turkey’s energy company Enerjisa Enerji installed on the roof of Galatasaray’s stadium in Istanbul won the Guinness World Records title in 2022.

The system will generate over 4 MWh annually for Borussia Dortmund’s own consumption

The announcement came a day before the Union of European Football Associations (UEFA) and SolarPower Europe partnered to advance sustainability in European football through solar energy.

Aligned with the sustainability goals and long-term vision of both Borussia Dortmund and JA Solar, this project will generate reliable green electricity for the next 30 years.

More than 11,000 modules will be installed on the stadium roof. The system will generate over 4 MWh annually for Borussia Dortmund’s own consumption.

The rooftop system is expected to reduce the club’s CO₂ emissions by about 1,800 tons a year, while significantly improving the stadium’s energy security and resilience.

Cramer: We are setting the course for a more environmentally friendly future

Installation is scheduled to begin in the summer of 2025, with completion targeted by the end of that same summer, JA Solar said.

Carsten Cramer, Managing Director of Borussia Dortmund GmbH & Co. KGaA, said that JA Solar would play a key role in the planned renovation of the photovoltaic system on Signal Iduna Park’s roof.

“With JA Solar’s modules, which will power the largest photovoltaic system on any stadium roof, we are setting the course for a more environmentally friendly future,” Cramer added.

According to Henning Schulze, Vice President of JA Solar, the company is proud that its modules will be used for this project at this iconic stadium. “In times of rapid political change and market disruption, our participation in this project is a clear statement from JA Solar that we are here to stay,” Schulze noted.

Hybrid solar, which combines solar with energy storage or wind, reduces the levelized cost of electricity by 10% compared to standalone projects, according to the latest report from SolarPower Europe.

Hybrid solar supports system flexibility, improves the cost-effectiveness of an asset, and makes energy generation more reliable, SolarPower Europe stressed.

“Embracing the benefits of Hybrid PV systems” reveals how hybrid projects enhance the security of supply by ensuring electricity generation even after sunset.

Hybrid solar projects have surged in recent years. Since 2015, solar (PV) + battery energy storage systems (BESS) have accounted for 5% of total BESS additions across Europe. The UK leads in hybrid PV+BESS installations, which make up 62% of total PV+BESS capacity, driven by strong policy support, market dynamics, and large-scale projects, according to the report.

PV+Wind hybrid projects, with only 555 MW installed, have yet to gain traction in Europe

In contrast, EU countries like Sweden (10%), Italy (8%), Germany (6%), Bulgaria (6%), and Denmark (5%) follow at a much lower level, with the rest of the EU-27 and Switzerland making up for only 3%.

The market for PV+Wind is equally concentrated, led by Poland with 277 MW, thanks to conducive policies and complementary generation patterns. However, in co-located setups, sharing the same connection point, regulations still need proper implementation.

The Netherlands (150 MW), Portugal (78 MW), and Denmark (7% share) have also advanced, with the UK and the rest of Europe lagging behind, with just 11 MW of PV+Wind, the report underlines.

Overall, PV+Wind hybrid projects have yet to gain traction in Europe, with only 555 MW installed by the end of 2024—less than 1% of the utility-scale solar fleet.

Five benefits

According to the report, Hybrid projects bring numerous benefits to end-users as they offer cleaner, cheaper, and more reliable electricity. The benefits can be distributed in five categories:

1. Resources utilisation. By combining different generation technologies, a more efficient usage of the existing resources can be achieved.
2. Efficient storage usage. Allowing hybrids to withdraw electricity from the grid enables an optimized system operation.
3. Cost reduction. Hybrid projects realize cost synergies by maximizing existing infrastructure usage and reducing the financing costs for renewables.
4. Curtailment avoided. By hybridizing renewables with storage, the surplus renewable output can be stored and injected later into the grid during hours of peak demand.
5. Increased reliability. Combining different generation technologies and/or storage increases the reliability of the energy output.

Hybrid systems offer a wide range of cost-saving benefits, including reduced expenses for grid connections, land use, project development (such as feasibility studies), and operations and maintenance (O&M). Hybrid projects can also reduce the project financing costs.

The levelized cost of electricity (LCOE) of a renewable generator is reduced under a hybrid project as a result of the savings in the investment costs and operational expenditures associated with the connection of the project.

Furthermore, the risk perception of a hybrid project can be decreased, seen both from the debt and the equity perspective, as the project outcomes are more predictable and/or can be further guaranteed in a PPA (i.e., less merchant risk).

SolarPower Europe sets policy recommendations

When comparing solar PV and storage hybrid systems to gas plants, the International Energy Agency (IEA) provides detailed modeling on how the LCOE for solar plus storage compares to that of coal in China and India, as well as gas in the US. The analysis shows that solar plus storage is significantly more cost-effective in these markets, often by more than 20%.

SolarPower Europe stresses that the EU is far from exploiting the full potential of hybrid solar systems, and the report brings key policy recommendations.
