Supermarket ASDA signed a five-year deal to use energy managing software at more than 660 sites today.
The renewed contract with smart firm Elster EnergyICT covers at least 10,000 meters across the UK.
Louise Hall, ASDA’s Energy Manager said the energy monitoring system, called EnactoTM 9.3, helped deliver “tangible energy and cost savings”.
It is a cloud-hosted platform which the makers say is “self-learning”, analysing data and alerting energy managers “to areas needing attention”.
Since 2005 ASDA has cut its energy use by nearly a third (30%) working with the smart firm.
It is committed to matching the 2020 target set by its parent company, Walmart, to slash energy usage by 20% compared with 2010 levels.
Walmart recently signed a deal with Elster across more than 2,000 of its stores in Mexico.
