OEE and Energy
OEE Software Powered by Wonderware
OEE doesn't only have the ability to affect your plant efficiency it has a direct relationship with your
energy usage.
Equipment that is running slowly or has lots of downtime will use more energy, most lines that start-up after a downtime require more energy to get back upto speed than normal running.
How much of your equipment is left standing producing nothing but consuming energy to keep them on standby or at operational temperature?
Statements for your consideration:
-
Scrap material uses as much energy as a good parts
-
A production Line running at 40% performance will be using 100% of the energy
-
A line running at 40% OEE will probably require double shifts to meet demands (this means you are probably using 100% more energy than you need to)
-
Many companies buy new equipment to meet demand when they would be better investing in optimising their existing equipment. If the equipment is running and not producing it is still using the same energy. When the new equipment is introduced this again increases the energy demand and energy waste
-
A company identified that a 5% increase in OEE would allow them to remove the Saturday shift and save £155k in energy costs a year
-
A company had 7 ovens and a 8% increase in OEE would allow then to turn an oven off saving £250k in energy costs a year
Alongside our OEE solutions we also provide a range of Energy Monitoring and Targeting (M&T) solutions.
-
Energy Monitoring and Targeting (M&T) is an effective management tool that allows you to find and diagnose energy wastage
-
Energy usage is related to driving factors such as the weather conditions, production rate, process equipment settings...
-
Understanding the driving factors allows targets to be set and energy usage monitored against these
-
The waste of energy can be signaled by a difference between the target and actual usage
