Should industrial batteries be subject to stricter performance and durability regulations for market access?
Energy Storage Europe has submitted formal feedback on a European Commission draft regulation aimed at setting mandatory performance and durability standards for industrial batteries. These proposed rules target rechargeable units exceeding 2 kWh to ensure they meet minimum quality requirements before entering the European Union market.
Why it matters
The proposed regulations aim to prevent manufacturers from bypassing quality standards by mislabeling new units as second-life batteries. Establishing these benchmarks is necessary to ensure consistent electrochemical performance across industrial energy storage systems.
The proposed European Union regulation mandates that rechargeable industrial batteries over 2 kWh meet specific, harmonized electrochemical performance and durability benchmarks. Compliance testing procedures remain under evaluation as the commission works to define requirements for temperature-regulated and safety-focused battery systems.
The players
Energy Storage Europe
An industry advocacy organization representing the storage sector, focused on regulatory policy and standardized battery performance metrics.
European Commission
The executive branch of the European Union responsible for drafting and enforcing pan-European market regulations and environmental standards.
The details
The regulation requires that industrial battery manufacturers prove the performance capability of their products through standardized testing. Energy Storage Europe is advocating for more formal, explicit definitions of what constitutes a 'first life' for a battery to prevent market gaming. The group also seeks clear technical distinctions for batteries used in dedicated safety infrastructure and those equipped with active temperature-regulation mechanisms.
Timeline
October 2025: The European Commission released the initial working document on battery standards.
October 29, 2026: Energy Storage Europe submitted its official response to the proposed regulations.
The Tech Race
This effort updates the framework of the European Union Batteries Regulation to address loopholes in industrial storage deployment. It represents a shift toward stricter, harmonized testing to ensure that high-capacity systems meet durability requirements before reaching the market.
These regulations will primarily affect industrial manufacturers and large-scale utility providers operating within the European Union by tightening product certification requirements. While the rules specifically target units above 2 kWh, the increased documentation requirements for battery 'first life' will eventually standardize the supply chain for industrial energy storage.
The takeaway
The implementation of these durability benchmarks aims to standardize the industrial energy sector and curb the use of mislabeled products. Stakeholders should monitor the commission for a finalized testing timeline, which will provide the specific compliance dates for market entry.
