Preserving Freshness: Dyness Smart Storage Safeguards High-Quality Dairy Cold Chain in Austria

Challenge: The “Freshness Battle” Under Triple Pressure

Cold chain logistics is a race against time—a battle to preserve freshness that demands extreme stability and timeliness.

As a key regional provider of dairy cold storage and logistics, Grufeneder must maintain 24/7 uninterrupted operation throughout the year. From refrigeration equipment to transport scheduling systems, every step relies on stable electricity. Any power outage can result not only in direct economic loss due to spoiled products but also in potential damage to the brand’s long-established reputation.

At the same time, the introduction of two eActros electric trucks with 600kWh battery capacity each significantly increased the overall electricity demand. Under Austria’s high electricity prices, charging these trucks during peak hours could sharply raise operational costs.

The combination of zero-tolerance for outages, high-load electric trucks, and volatile electricity prices created an urgent need for an energy solution that balances reliability and cost efficiency.

Solution: Building an Integrated “Solar + Storage + Charging” Energy System

Focusing on core customer needs, Dyness deployed a highly reliable and flexible commercial and industrial storage system centered on STACK100 batteries, with a total capacity of 1.3MWh (24 clusters × 11 modules), achieving synergistic optimization of generation, storage, and consumption. 

1.Total Reliability: System-level full backup with zero-tolerance for outages

The high-performance Dyness STACK100 batteries, integrated with PCS, EMS, and power distribution circuits, provide system-level backup power and intelligent energy management for critical loads. In the event of a grid outage, the system automatically switches in milliseconds, ensuring that compressors, temperature control systems, lighting, and other key cold storage loads continue running. Even under extreme weather or grid instability, Grufeneder’s dairy products remain safely stored at stable low temperatures.

2.Cost reduction and efficiency: Peak shaving for truck charging

The two eActros electric trucks are pioneers in green transportation but represent a significant load on the grid. The Dyness storage system complements grid power, enabling peak shaving and valley filling during truck charging. This ensures stable charging while optimizing electricity use and reducing transport energy costs.

Additionally, the storage system works in tandem with solar generation, achieving a true “solar + storage + charging” integration: daytime solar energy is stored in batteries, and trucks are charged in the evening—maximizing self-consumption and optimizing costs through storage arbitrage.

STACK100 – the “Peak Shaving” Weapon for Energy Costs

• High-performance & reliable: STACK100 supports 1C charge/discharge (100A), peak discharge current of 125A (25℃, 2 minutes), and 95% depth of discharge, responding rapidly to load fluctuations. Its high-speed switching ensures critical cold chain, data center, and medical loads remain powered, minimizing product loss and operational disruption.

• Modular & scalable: Blind-plug stacking allows 3–15 modules per cluster, with up to 12 clusters in parallel, covering 15kWh–921kWh, enabling flexible expansion for growing loads. The current 1.3MWh setup meets both cold storage and two electric trucks while leaving room for future growth.

  
  

• High safety & reliability: Multiple protection layers—temperature sensors, intelligent fire prevention, over-temperature/current/voltage protection, optional self-heating modules—ensure stable operation even in winter -20℃ environments and complex conditions.

• Intelligent management for lower energy costs: Built-in Wi-Fi, paired with Dyness EMS and smart app, supports peak shaving, demand management, backup power, and solar-storage coordination, optimizing charge/discharge based on price signals and load, reducing overall energy costs.

Value: Setting a Benchmark for Green Cold Chain Transformation

The Grufeneder project is a successful example of integrated solar + storage + charging in Austria and a demonstration for high electricity price regions in the EU.

Triple benefits for Grufeneder:

• Safety: Mitigates power outage risks, protects product quality, and safeguards core cold chain assets. 

• Economic: Storage arbitrage and optimized truck charging reduce electricity costs, shorten ROI, and lower total energy costs by 20–35%. 

• Green: Maximizes renewable consumption, enabling low-carbon operations from storage to transport, integrating clean energy with green logistics.

  
  

Outlook: From “Preserving Freshness” to “Activating a Green Future”

Cold chain logistics ensures temperature-controlled safety for fresh food and pharmaceuticals, and advanced storage technology is key for emergency supply and cost optimization. With the rise of electric transport and distributed energy, the industry is moving toward smarter, more efficient energy systems. By 2035, the European cold chain logistics market is expected to grow under the dual drivers of food safety and sustainability.

Dyness will continue to advance storage technology and multi-scenario integration, expanding “solar + storage + charging” solutions, helping more enterprises achieve safe, economical, and green development.

From “preserving freshness” to “activating the future”, Dyness leverages intelligent energy storage to empower global industries for a greener transformation.
