CUES Delivers Phenomenal 3 Month Payback at Safeway!
Brief Overview
Safeway are one of the largest grocery retailers
in North America with over 1,775 stores. They
have a strong commitment to environmental
protection, which includes adopting proactive
measures to minimise waste. In harmony with
this policy, a prominent division of Safeway
agreed to trial CUES on one of their frozen Warehouses. This resulted in a stunning payback of 3 months.
Following several consultations, they agreed
a before and after trial with CUES on one of Safeway’s largest energy consumers. Refrigeration represents a huge proportion of Safeway’s energy bill and they were understandably eager to lower their costs and follow through on their commitment to reduce waste and minimize their carbon footprint.
An energy reduction of 5,063kWh or 12%
The Project
During a two week monitoring period WITHOUT CUES the compressor for the warehouse
consumed 43,174kWh of energy. Following this initial test, CUES was installed and the compressor was monitored over the same time period. During the second test WITH CUES…
…the compressor used 38,111 kWh of energy. This demonstrated an energy reduction of 5,063kWh or 12%.
Although this represented an excellent result, it
was noted during the second test that the air
temperature inside the freezer was consistently
two degrees colder than it was during the first
test – revealing the potential to increase the
savings by increasing the set-points on the
internal thermostats by two degrees.
This would likely bring the average freezer
temperature back to its original operating
condition, while further reducing the energy
consumed.
