Delivered savings in Tesco are from 12 to 20% across the Express estate and over 30% on lighting schemes in the larger Extra stores.
Case Studies
Energy efficiency projects deliver great returns
Tesco is the UKs largest grocery retailer and in 2006 accounted for £1 in every £3 that the British public spent on essential foodstuffs. Their estate ranges from local Tesco Express convenience stores to town centre Metro outlets and 24/7 Extra and Superstores totalling nearly 1,000 sites in all. The group has established Energy and Environmental initiatives targeted at reducing consumption by up to 50% in the next 5 years.
Challenges
Complex site operations, from 7/16 to 24/7 operations
Smaller site equipment from basic refrigeration and lighting to on-site bakeries, ovens, air-conditioning and extraction
Larger sites with 24/7 operations, BMS and AHU systems
Regular changes of opening/closing hours
Differential age and condition of sites and control technologies
Variation in local management practise
Solutions
All Half Hour profiles available on-line via web reporting
Installation of web-based IET control on all Express sites
Implementation of BMS outstations on Metro sites
Energy reduction projects on lighting control schemes in Extra stores
Rapid roll-out of 50+ stores per week to maximise returns
Vitally, all sites are monitored 24/7 via Evolve’s Energy Operations Centre to ensure savings are maintained and equipment is running correctly
These are reporting examples of energy profiles from Tesco stores. The client uses this on-line data to compare before and after profiles and therefore establish the effectiveness of Evolve’s energy reduction projects.
From initial trials during the summer of 2006 Evolve has been rolling out across the entire Tesco estate. Delivered savings are from 12 to 20% across the Express estate and over 30% on lighting schemes in the larger Extra stores.
Energy efficiency projects deliver great returns, generally around 2 years or less depending on what tariff you’re on so Tesco sees it as common sense business. Added to that it’s great for the environment – we’ll make significant cuts to carbon output by simple measures with energy efficiency so it’s great for businesses and great for the environment. Evolve has done a great job for Tescos. They were able to hit up to 50 stores per week with simple measures that work and are effective and these measures are also sustainable for the long term. So we go into small stores especially, make a step change in energy, and sustain that step change going forward so they’ve done a great job for Tescos.
