Tesco has cut its energy expenses by 10% in eight distribution centres with the help of new AI technology. Tesco and the refrigeration company, Star Refrigeration used its Ethos AI System for the trial which involved raising the temperature of its fridges by one degree. Its Ethos AI system helped Tesco save 4GWh on energy costs and more than 835 tonnes of CO2e throughout its refrigerated distribution network over 21 months.

Tesco’s group energy manager Rob Redfern said: “We’re very proud to say that we have reduced energy consumption by an average of 10% across those distribution sites in the short period between January 2022 and September 2023, achieving a return on investment in under three months.”
