Overview of the PV & ESS Safety Industry Summit 2026

On June 24, 2026, the inaugural PV & ESS Safety Industry Summit was held in Munich at Intersolar Europe, organized by Huawei Digital Power alongside various global partners. This event marked a significant step towards addressing critical safety risks associated with the large-scale deployment of photovoltaic (PV) and energy storage systems (ESS). As the world increasingly shifts towards renewable energy solutions, this summit aimed not only to uncover the challenges faced but also to create a collaborative environment for industry experts, insurance representatives, and organization leaders to discuss safety standards and innovations.

Key Themes and Discussions

During the summit, key subjects such as safety risks, the disparity between insurance coverage and actual risks, firefighting challenges, and innovative insurance solutions were tackled. Attendees were introduced to a pioneering safety framework that aspires to enhance safety measures within the renewable energy sector. Huawei representatives emphasized the necessity of cross-disciplinary integration — combining electrochemistry, thermal management, power electronics, digital technology, and artificial intelligence — to ensure that PV+ESS security evolves to meet modern demands.

Importance of Safety in the Energy Transition

Xia Hesheng, Vice President of Huawei Digital Power, highlighted that the safety of PV and ESS is not merely a choice but a crucial requirement. He indicated that achieving safety would necessitate not just technological breakthroughs but a comprehensive strategy involving multiple fields of expertise. Huawei has committed to long-term investments in safety technology innovations to guarantee the security of the entire supply chain. The focus is also on integrating quantitative safety assessments with insurance mechanisms to promote high-quality development across renewable energy sectors.

Global Perspectives on Safety Challenges

During the discussions, key figures in the energy industry brought attention to the growing significance of energy storage systems in relation to the 'de-rating crisis'. Gerrit Lührung from the German Storage Systems Association (BVES) pointed out that the current BESS capacity in Germany stands at 19 GW, primarily driven by the utility, commercial, and industrial sectors. Yet, the industry faces regulatory limitations that need to be overcome within the next three years to fully utilize the potential of the energy system under new safety guidelines.

Tom Hessels, an energy and transport safety advisor at the Dutch Institute for Public Safety (NIPV), raised concerns about the increasing frequency of battery fires, recommending the sharing of UL 9540A test data and consistent manufacturer support channels to alleviate the information gaps faced by fire services.

Mikel Arrese-Igor, a senior engineer at DNV, underscored that roughly 70% of BESS failures occur at the system level, stressing the importance of full-scale testing to validate safety philosophies. Increasing the testing standards to encompass installation levels and other non-battery housing scenarios was advocated to promote comprehensive safety practices.

Technical Challenges and Innovations Ahead

Addressing technical challenges, Zhu Jun from Huawei Digital Power identified four critical hurdles: overcoming thermal runaway limitations, high-voltage insulation failures, grid disruptions, and digitalization deficits. A full lifecycle quantitative safety assessment framework must be established to elevate the risk levels from 'Zone B risk reduction' to an 'acceptable Zone C'. Huawei has developed a robust defense network, built on passive protection and proactive early warning systems. This includes heat-resistant insulation and AI-driven technologies to avert thermal runaway in extreme conditions.

The Role of the Insurance Sector

Alastair Nicklin from WTW emphasized the necessity for the insurance industry to evolve its approach to risk management. This includes shifting focus to design as a tool for risk mitigation, quantifying risk probabilities and damage severity to create a robust defense mechanism that encompasses physical, financial, and environmental dimensions. This new direction should prioritize the management of risks within close confines rather than implementing broader safety distances alone.

Conclusion and Future Outlook

The summit concluded with the unveiling of the Grid-Forming ESS Safety White Paper, which outlines the framework for quantitative safety assessment, attack-defense testing systems, and pathways for future digital advancement. This document proposes principles for a data-driven approach and closed-loop iterations, contributing to a unified safety framework within the sector. The ongoing dialogue and collaboration fostered at the summit underscore the industry's commitment to achieving higher safety standards for the transition towards a sustainable energy future.
