Cold-Chain Intelligence for Safer Food and Lower Energy Bills

How a European Grocery Retailer Modernised Refrigeration Compliance and Cut Energy Costs with an IoT-Driven Platform

A leading European grocery retailer, managing hundreds of stores across the continent, faced a dual challenge: ensuring compliance with increasingly strict cold-chain regulations while reducing energy costs in a context of tight margins. Manual checks and disparate legacy systems had become slow, audit-heavy and incapable of delivering real-time visibility. The management team therefore decided to move from fragmented oversight to a scalable, secure and reliable IoT-driven infrastructure.

The Challenge: Compliance and efficiency in a fragmented environment

The company knew that continuing to manage cold-chain compliance with paper logs and outdated systems meant mounting risks. Each inspection demanded significant staff time, while the absence of centralised visibility made it difficult to anticipate failures. Rising energy costs and the complexity of operating equipment from multiple vendors only made matters worse. In practice, the cold chain had become a critical bottleneck, exposing the organisation to compliance risks, operational inefficiencies and unnecessary costs.

The Solution: An IoT platform designed for scale, trust and Cold-Chain Intelligence

With Uniquon’s support, the retailer introduced a next-generation IoT platform capable of collecting data from retrofit sensors installed in refrigerators, freezers and storage facilities, transmitting it securely to a cloud-native architecture built for high-volume data and resilience. Local gateways ensured continuity even in the event of connectivity loss, while the cloud analytics engine combined historical data, rule-based alerts and predictive models to detect anomalies before they became emergencies.

At the centre of the solution sits an intuitive, scalable dashboard that provides managers with a unified, real-time view of the cold chain across all sites. Compliance reports are generated automatically and made available instantly to auditors, while energy data is seamlessly integrated with existing management systems. Beyond monitoring, the platform delivers actionable Cold-Chain Intelligence —optimising defrost cycles, fine-tuning set points, and analysing door-opening patterns to improve both efficiency and product safety.

The Impact: Safer food, measurable savings, stronger reputation

Within nine months of deployment, the impact was already clear. Compliance processes were automated, drastically reducing administrative overheads and ensuring audit readiness at all times. Cold-chain incidents were almost halved, as anomalies were detected and resolved in real time.

On the energy front, the solution delivered average reductions of between twelve and eighteen per cent in refrigeration consumption, with significant savings on operating costs and measurable progress towards the retailer’s ESG commitments. At the same time, benchmarking across equipment models provided powerful insights for future capital expenditure, aligning investment decisions with performance data.

As one executive commented: “Today we can demonstrate compliance at the click of a button and know exactly where energy is being wasted. The platform paid for itself far faster than we had anticipated.”

What’s next

Encouraged by the success of the initial rollout, the retailer is now extending the platform to cover freezer systems, distribution centres and central plants, while piloting computer-vision solutions to minimise warm-air ingress during peak hours. With this approach, the cold chain is no longer simply a cost of doing business, but a competitive advantage that combines food safety, operational efficiency and environmental sustainability.
