The Problem
Energy reduction was entirely reactive — improvements happened by gut feel, with no way to see usage as it happened.
The Approach
Renteknik deployed real-time monitoring so the team could track energy usage every shift, every hour — down to the granular level, plant-wide and process-by-process.
The Results
A purchase justified on a 12-month ROI paid back in six. Cost-per-unit moved from estimate to measured fact.

From gut feel to engineered certainty
The bill used to tell the story. Now the data does.
- Usage tracked live — every shift, every hour
- Cost per unit measured, not estimated
- 12-month ROI achieved in just 6 months
- Carbon neutrality now trackable, plant-wide
“I use the system on a weekly basis, daily basis. I do oversight of the whole plant, but I can also go down to a granular level and understand what’s going on with particular parameters — how it’s allowed us to reassess our cost per unit rather than work off an estimate.”
