Climate-related network risk: Heatwaves, electricity grid stress, peak cooling demand, rising energy costs and disruption to refrigerated warehouse operations
Solution pathway: Demand response, flexible refrigeration management, thermal storage and participation in virtual power plant programme
Business type: Large temperature-controlled logistics and warehousing operator
Sector: Refrigerated warehousing, food storage and cold chain logistics
Geography: Australia
In practice
Refrigerated warehouses are energy-intensive assets that must keep food products within strict temperature ranges. This makes them particularly exposed to climate-related energy risks. During heatwaves, cooling demand rises across the whole electricity system as homes, businesses and infrastructure use more air conditioning and refrigeration. At the same time, refrigerated warehouses may face higher electricity costs, tighter grid conditions and greater pressure to maintain continuous cooling.
Oxford Cold Storage’s Laverton North site in Victoria stores chilled and frozen products including meat, dairy and other food products. The site has a large, continuous electricity demand because refrigeration is central to its operations. Before participating in demand response, the business had already made substantial energy-efficiency improvements, allowing it to increase storage capacity without increasing total electricity consumption. However, rising electricity costs meant the business needed to look beyond conventional efficiency measures.
Working with Enel X, Oxford Cold Storage participated in demand response programmes as part of a virtual power plant. This enabled the site to temporarily reduce electricity demand when the grid was under pressure. One programme supported short reductions in load to help maintain frequency in the National Electricity Market. Another was designed for periods of unusually high demand, including heatwave conditions, when electricity demand from air conditioning and cooling is especially high.
The approach used the thermal inertia of the cold storage facility. Because refrigerated warehouses are well insulated and contain large volumes of chilled or frozen product, they can sometimes adjust refrigeration loads for short periods without temperatures moving outside safe operating limits. With monitoring, controls and operational planning, refrigeration demand can be reduced, shifted or managed while still protecting food safety and product quality.
For Oxford Cold Storage, this meant the warehouse could reduce demand during peak events without disrupting normal operations or compromising stored goods. The model also created a financial benefit by helping offset rising electricity costs. More broadly, it showed that cold storage facilities can act as flexible energy assets rather than simply fixed energy loads.
The case is useful for this section because it connects cold chain resilience directly to energy system resilience. As climate change increases the frequency and intensity of heatwaves, refrigerated warehouses may face both higher cooling needs and more stressed electricity grids. Demand response offers one practical way to manage this risk: using the existing flexibility of cold storage infrastructure to reduce peak load while keeping products safe.
Why this example was selected
This case study was selected because Oxford Cold Storage / Lineage Logistics is a well-documented example of demand response in the cold chain sector. Enel X published the project as a customer case study, describing how the facility used virtual power plant participation to reduce demand during peak grid events while maintaining operations and quality.
The case has also been featured in the Australian business energy briefing Navigating a Dynamic Energy Landscape, which profiled Oxford Cold Storage as an example of industrial demand response in practice. Oxford Cold Storage was also publicly covered by ABC News as one of the large industrial participants showing how businesses could reduce demand, support grid stability and lower energy costs.
This makes the case valuable for the platform because it shows a practical adaptation pathway that is relevant beyond a single company. It demonstrates how cold chain operators can use insulation, monitoring, controls and operational flexibility to manage climate-driven energy stress. It is especially relevant for food businesses, retailers, logistics providers and warehouse operators whose product integrity depends on reliable refrigeration.
Key lesson
Cold chain operators should assess whether refrigeration loads can be safely shifted, reduced or pre-cooled during peak demand periods. With good insulation, monitoring and controls, some warehouses can reduce energy risk and support grid resilience while still protecting product integrity.
