Paving New Paths at the 2026 PV & ESS Safety Industry Summit

On June 24, 2026, the inaugural 2026 PV & ESS Safety Industry Summit was held in Munich as part of Intersolar Europe 2026. Sponsored by Huawei Digital Power alongside its global partners, this summit addressed the intricate safety risks and insurance discrepancies emerging from the vast development of Photovoltaic (PV) and Energy Storage Systems (ESS), all within the context of the global energy transition.

Key Discussions and Highlights

The summit brought together renowned experts, association representatives, and insurance officials to engage in comprehensive discussions on energy storage safety standards. Topics included the challenges surrounding fire emergencies, the evolution of testing methods, and innovations in the insurance domain, collectively aiming to chart a new course towards safer and more reliable energy developments.

Emphasis on Safety

Xia Hesheng, Vice President at Huawei Digital Power, stressed the critical importance of safety in PV & ESS systems as a necessity rather than a choice in the burgeoning new energy system landscape. He explained that achieving safety is not merely about singular technological advancements but requires integrating various disciplines, such as electrochemistry, temperature management, power electronics, digital technologies, and artificial intelligence. Huawei remains committed to its principle of 'quality first' and continuously invests in innovations related to safety technology for photovoltaic and energy storage systems, ensuring safety throughout the supply chain.

Global Breakthrough in Safety

The summit featured insights from Gerrit Lührung of the Federal Association of Energy Storage Systems (BVES), who stated that energy storage has evolved from a mere commercial tool to a critical systemic element amid the ongoing supply constraints. With the total battery energy storage capacity in Germany standing at 19 GW, propelled by energy providers, commerce, and industry, Lührung noted the industry's need to navigate regulatory challenges and embrace new safety directives in the coming three years.

Tom Hessels, an energy and transport safety advisor, pointed out the rising incidence of battery fires, attributing part of this trend to information gaps. He called for transparent testing results as per UL 9540A standards and suggested establishing continuous support channels for manufacturers to bridge the information gap between firefighters and producers.

Mikel Arrese-Igor from DNV highlighted that about 70% of BESS system failures occurred at the systemic level, asserting that real-world testing, such as those conducted in Huawei's LUNA2000 systems, is crucial for validating safety philosophies that prioritize security from the design phase.

Evolving Standards

The industry anticipates modifications in testing norms to encompass installation levels, particularly concerning chain fire scenarios involving adjacent structures that are not battery components, explained Bill Reaugh from the VDE. He emphasized that energy system transformations introduce new risks, necessitating a shift in safety development from components to holistic ecosystems utilizing a model of digital trust and encompassing the entire lifecycle from design to operation.

Achieving Technical Excellence

Zhu Jun from Huawei pointed out four significant challenges that need addressing: thermal runaway thresholds, high-voltage isolation failures, issues within distribution networks, and insufficient digitization. To enhance risk levels from 'Risk Zone B' to 'Acceptable Zone C,' a longitudinal framework for quantifying safety throughout lifecycle stages should be instituted. Huawei has established a defense network integrating passive protection with proactive warning systems, ensuring that extreme situations do not lead to the spread of thermal runaway incidents.

Alastair Nicklin from Willis Natural Resources advocated for the insurance industry to pivot towards a paradigm that quantifies design as a risk control mechanism, merging risk probability with damage severity to create a three-dimensional defense framework encompassing physical, financial, and environmental dimensions. By expanding fire safety boundaries even to the microenvironment insulation levels, he underscored the importance of protective measures against revenue loss due to equipment failures.

White Paper Release

During the summit, a white paper on Grid-Forming ESS safety was released, focusing on quantitative assessment frameworks, testing systems, and pathways toward digitalization. The document addressed defense enhancement via offensive strategies, data-driven approaches, and iterative closed-loop frameworks, guiding the industry toward a unified paradigm of safety.

The 2026 PV & ESS Safety Industry Summit marks a significant step forward in ensuring safety as a critical component of technological advancement in the renewable energy sector, fostering collaborations aimed at sustainable growth and resilience.
