Recently, the commercial and industrial energy storage project developed by Xinrui Energy in Toledo, Spain, has been fully completed and officially handed over. Boasting a total energy storage capacity of 1.044 MWh, the project adopts the company’s self-developed 261 kWh liquid-cooled all-in-one energy storage units deployed in parallel with four units. It delivers a localized, safe, high-efficiency and high-yield energy storage solution for a local manufacturing enterprise, marking a landmark operational project for Xinrui Energy’s expansion into Europe’s commercial and industrial energy storage market.
A groundbreaking ceremony was held in the early stage of the project, attended by representatives of the project owner, local partners and Xinrui Energy’s project team. All parties coordinated to formulate the overall construction plan, and conducted in-depth collaboration on core matters including overseas construction codes, outdoor equipment adaptability and grid connection specifications. The full-process chain covering equipment shipment, cross-border transportation, on-site construction and system commissioning was streamlined to ensure orderly construction and on-time delivery of the project.
Faced with multiple challenges of overseas European projects — tight construction schedules, stringent construction standards and complex outdoor operating environments — Xinrui Energy leveraged its integrated energy storage product strengths and mature overseas delivery system to drastically shorten on-site construction cycles and efficiently complete all construction procedures.
The core equipment of this project is Xinrui Energy’s 261 kWh outdoor liquid-cooled all-in-one energy storage unit. Featuring a highly integrated factory pre-assembled design, the unit comes pre-installed with PCS, battery clusters, liquid cooling temperature control, BMS battery management and fire protection systems, enabling plug-and-play operation. Its modular structure supports flexible configuration and capacity expansion via parallel connection of multiple units, adapting to varying power load demands of enterprises and enabling rapid on-site deployment.
The product’s core advantages make it an ideal fit for outdoor commercial and industrial scenarios across Europe:
Easy transportation & installation, cost and efficiency optimizationFully prefabricated at the factory, the unit requires no disassembly or assembly on-site. It drastically cuts civil engineering and wiring workloads, shortens delivery cycles and effectively lowers customers’ overall construction costs.
Perfluorinated Hexanone Full-Spectrum Fire Suppression with Multi-Layer Safety ProtectionEquipped with a clean perfluorinated hexanone fire extinguishing system, paired with multi-layer safety mechanisms including battery thermal runaway early warning, overvoltage/overcurrent protection and insulation monitoring, it eliminates potential energy storage safety risks at the source.
IP54 Outdoor Protection for Stable All-Weather OperationWith an IP54 ingress protection rating and an integrated liquid cooling constant temperature control system, the unit operates reliably across a wide temperature range. It perfectly adapts to harsh outdoor conditions in Spain, such as high temperatures and large day-night temperature swings, delivering uninterrupted stable operation all year round.
During construction, Xinrui Energy’s construction team followed European power construction standards to carry out standardized on-site installation work, including precise positioning of equipment foundations, neat layout of high and low voltage cables, and standardized grounding and grid connection construction, with full-process strict quality control.
After equipment delivery and layout, the technical team conducted full-unit power-on joint commissioning. Every sub-system — liquid cooling temperature control, intelligent BMS, perfluorinated hexanone fire protection and EMS energy management — was inspected and tested item by item. Multiple operating conditions including charge-discharge cycles, load fluctuations and power failure emergencies were simulated repeatedly to troubleshoot and optimize operating parameters. This ensures stable operation and precise response of the entire energy storage system, meeting the factory’s round-the-clock power supply demands.
In April 2026, the Toledo energy storage project in Spain finished all commissioning work, achieving full completion, delivery and commercial operation. Once put into service, it will bring tangible multi-fold benefits to the local manufacturing enterprise:
Peak shaving and valley filling to cut electricity bills: Low-cost off-peak electricity is stored and discharged for self-consumption during peak tariff periods by leveraging peak-valley electricity price gaps, sharply reducing peak power costs and shortening the investment payback period.
Emergency backup power for outages: Seamless power switching is triggered in case of sudden grid blackouts to keep core production lines running and avoid losses caused by production shutdowns.
Stable power supply for daily manufacturing: It mitigates grid voltage fluctuations and improves power quality within the factory, laying a solid power foundation for continuous and stable production.
The system comprehensively lifts the enterprise’s power utilization economic benefits and facilitates the green and low-carbon energy transition of local commercial and industrial entities.
The successful delivery of the Toledo commercial and industrial energy storage project in Spain represents a key milestone of Xinrui Energy’s liquid-cooled integrated energy storage products entering the European market, fully verifying the adaptability and delivery capacity of the company’s products under complex overseas environments and stringent standards.
Moving forward, Xinrui Energy will continue to deepen its presence in the global commercial and industrial energy storage track, iterating the core technologies of its liquid-cooled all-in-one energy storage units centered on safety, integration and high efficiency. The company will export standardized, one-stop energy storage solutions to overseas markets including Europe, Southeast Asia and the Americas. With reliable energy storage technology, Xinrui Energy will empower the green and low-carbon development of commercial and industrial sectors worldwide and accelerate the global energy transition.
