The Economics Behind Morrisons' Freezer Temperature Boost

You’re walking through the frozen food aisle at your local Morrisons, and unbeknownst to you, a quiet revolution is taking place inside those freezers. Morrisons has decided to raise the temperature of their freezers from -18°C to -15°C. At first glance, this might seem trivial, but economically, it’s a game-changer. Let’s dive into the economic implications of this bold move.

Economic Efficiency: Reducing Variable Costs and Boosting Margins

Morrisons’ decision to increase freezer temperatures is a strategic move aimed at reducing energy consumption and operational costs. Energy constitutes a significant portion of operating expenses for supermarkets, especially for refrigeration. By raising the temperature by 3°C, Morrisons anticipates a reduction in energy usage by 10-11%. This translates directly into cost savings, allowing Morrisons to potentially lower prices for consumers or improve profit margins.

Economies of Scale: Amplifying Savings Across Stores

This trial involves only 10 stores, but the plan is to expand it nationwide if successful. The principle of economies of scale suggests that as the scale of operation increases, the per-unit cost of operation decreases. If Morrisons can implement this change across all its stores, the cumulative savings could be substantial, reinforcing its competitive position in the market.

Environmental Economics: A Dual Benefit

Reducing energy consumption has a dual benefit: lowering costs and reducing carbon emissions. The University of Birmingham and Heriot-Watt University project that a 3°C increase in freezer temperatures across global supply chains could save 8.6% of the energy consumed in the UK. This reduction is akin to removing 3.8 million cars from the road, representing a significant environmental impact. From an environmental economics perspective, this move aligns with global efforts to combat climate change while enhancing Morrisons’ sustainability credentials.

Market Dynamics: Staying Competitive

Morrisons has been struggling since a debt-laden takeover in 2021. In a fiercely competitive grocery market, any opportunity to cut costs without compromising quality is crucial. By adopting more energy-efficient practices, Morrisons can reinvest the savings into competitive pricing strategies, store improvements, or debt reduction, all of which can improve its market position.

Technological Innovation and Industry Standards

Historically, the standard freezer temperature of -18°C has been more about convention than necessity. With modern advancements in refrigeration technology, it is now possible to maintain food safety and quality at higher temperatures. This technological progress allows businesses like Morrisons to challenge outdated standards, leading to industry-wide changes that enhance efficiency and sustainability.

Risk Management: Ensuring Food Safety

One of the critical concerns with changing freezer temperatures is food safety. However, studies by Nomad Foods and Campden BRI have shown that raising the temperature to -15°C does not compromise the safety, texture, taste, or nutritional value of food. This ensures that Morrisons can achieve cost savings without risking customer trust or food quality, mitigating potential risks associated with such a significant operational change.
