Turning the cold room into an energy flexibility asset

As a production site, Maison Dandoy's energy usage is intense. On one side, their already existing solar panels were producing lots of unused energy during peak production hours, with only 44% of self-consumption. On the other side, cold storage to keep chocolate at the right temperature was consuming lots of energy throughout the day, even when solar panels weren't producing.

Thanks to the WISE. Brain, we were able to understand how to increase self-consumption of solar energy without adding additional operational burden: in particular, we were able to automatically modulate the cold room's temperature setpoint to absorb solar surplus at the right moment, turning an existing energy load into a flexible asset. We’ve estimated that our collaboration will allow Maison Dandoy to increase their self-consumption by 6%, reduce their energy bill and reduce their greenhouse gas emissions by 3 T CO₂e per year, all with zero operational burden for them.
