There are two ways to mitigate the rising cost of energy:
For manufacturers there are plenty of opportunities to reduce the amount of energy within your factory. We will explore 5 ways that will provide quick returns:
Energy management is a team game – it starts at the top, is influenced by the administration staff and is delivered by the shop floor teams.
The roles of each group are well defined in terms of their contribution to reducing energy usage:
“Don’t forget to turn off your equipment.”
“Switch off the lights when leaving the room.”
“If we reduce our energy bills, we may have enough savings to invest in new equipment to make your job easier. We cannot do this without you.”
Bring these three groups together into an Energy Team. Their aim is firstly to communicate the need to reduce energy. Secondly to identify waste energy and to come up with ideas to eliminate the waste energy. Lastly, the Energy Team should have responsibility (and remuneration!) to implement ways of working or energy efficiency technologies to eliminate waste energy.
Pull out the electricity bills since January 2019 and look at the kWh figures for each bill per month. If they are based on a half-hourly meter you will know that they are accurate, if not they may be based on an estimate which is not helpful but will still give you a steer in the right direction. January 2019 is a great starting point as it gives you a full year pre-pandemic, 18 months of the pandemic and at least a year post pandemic.
Plot the figures against your production output figures over the same period on a monthly basis. This will give you a trend of energy usage vs production which may show you the following:
Pre-, during-, and post- Covid electricity trends will show you if you are able to manage energy based on variable occupancy levels. Our experience is that facility energy usage did not change through the pandemic but output fell significantly in many industries. This is a huge opportunity to find the waste energy and eliminate it!
