About Castell Howell.
From their main depot at Cross Hands and their four satellite depots at Avonmouth, Blaenau Ffestiniog, Chirk and Merthyr Tydfil, Castell Howell service the length and breadth of Wales, the Welsh borders and the West Country. Providing top quality produce, Castell Howell is well established as one of the country’s leading independent food wholesalers.
Castell Howell takes their commitment to the environment very seriously with a number of environmental initiatives. In 2012 they were one of the first companies in Wales to sign to the WRAP Hospitality and Foodservice commitment to reduce food and packaging waste. Continuing with their commitment to reducing their environmental impact, Castell Howell have set their sites on significantly reducing their energy consumption, from replacing critical plant equipment with more energy efficient alternatives, to exploring process and behavioural driven change programmes.
What did we do for Castell Howell?
MY ZeERO installed 8 Power Distribution Monitors at the Cross Hands Distribution Centre. This gave them real-time circuit level detail of energy consumption throughout the entire site. As a result, there were a number of success stories connected to the project.
The Results.
One example was of the site’s Waste Compactor. MY ZeERO highlighted that this single electrical supply had an unusually high base load, producing a cost of c.£230 per month. Upon investigation, it was learned that this supply also carried a spur to a now‐unused area, where a fan heater was constantly running! This discovery lead Castell Howell to disconnect the fan heater, resulting in savings of c.£180 per month, or £2,000 per year.
Another example came from the study of habits – such as the vans that return to the site empty around midday were immediately plugged in for charging of the refrigeration equipment. They were not scheduled to be restocked until around 18:00 that evening. The vans only require an hour or so to be adequately refrigerated, so this was recognised as 4 or 5 hours per van per day of unnecessary usage. Addressing this has delivered a cost saving of c.500 per month, or £6,000 per year Castell Howell were also undertaking a number of other energy efficiency programmes across the year. The availability of real‐time circuit level detail was invaluable in validating several key projects.
