Iceland – a Utilitywise case study

Iceland – a Utilitywise case study

How we helped Iceland optimise their lighting in 850 stores.

Key Facts

  • Implemented a bespoke IoT enabled controls solution incorporating energy market analyst and engineering expertise
  • Savings of 15% achieved on store lighting alone in the first year equivalent to over 3,100 tonnes of carbon
  • A further 10% savings projected through the implementation of load shedding (cutting consumption) and load shifting (moving consumption to off-peak periods) strategies


Iceland is the UK’s leader in frozen food. As a national multi-site business, it’s imperative that they have visibility and an in-depth understanding of where, when and how they use energy and the power to control it. Utilitywise has the expertise to assist with this. We provide innovative software to enable users to track energy usage in real-time, 24 hours a day, 365 days a year. Plus, our Building energy Management Systems (BeMS) and Internet of Things (IoT) technologies offer our clients the ability to connect energy intensive devices across multiple sites.

Trusted advice

We worked closely with Iceland to provide an optimised lighting control system to be rolled out across their 850 stores. This bespoke IoT/controls solution was designed and implemented by our engineering teams who worked alongside key stakeholders within the supermarket chain to ensure the technology fulfilled their requirements. This technology now provides Iceland with automation of store lighting to optimise the energy consumption based on occupancy and trading times. The lighting has been split into zones and is controlled via a combination of timed outputs, alarm interfaces, and presence detection. Some stores have also seen the connection of AHUs allowing for remote control of internal environmental temperatures and remote fault-finding for maintenance purposes. The implemented BeMS has achieved a 15% savings in Icelands lighting bill across 850 stores in the first year alone. Additional opportunities are also being investigated to identify further savings. Our team are working closely with Iceland to implement load shedding and load shifting activities to reduce electricity charges at peak DUoS and TNUoS times. By programming additional logic for the lighting and AC systems, Iceland can shift load from these time bands and reduce their bills further. This activity is expected to deliver a further saving of up to 10% of their energy bills.
