How is Toshiba Adapting its Production Methods and Planning to Reduce its Energy Bill by 4 Million Euros in 2023?

Posted on: 4 January 2023

Analyzing, simulating production at different times, on different lines simultaneously, and conducting data analysis are examples of actions that Toshiba implemented in late 2022 with the help of MyDametis to limit the impact on energy costs.

MyDametis, a Decision Support Tool

Mohamed Mebtoul, Toner Department Director at Toshiba, explains the importance of such a tool for decision-making: “MyDametis has allowed us to understand down to the kWh how much we consume compared to our production, or even how we consume when we are idle. We can also simulate kWh distribution on production lines and know when it is best to operate our processes.” This reflective work is essential for opting for effective solutions.

Among the decisions made, the most important ones include the rearrangement of work schedules: concentrating resources and production personnel from a 3X8 system into a new 2X8 night system and 2×24 hours on weekends to benefit from off-peak rates. This new organization should allow a shift from a 35% off-peak ratio to over 80% off-peak and favor load shedding during peak hours on very cold days. These decisions will drastically reduce the energy bill of the toner production plant by -25%.

“MyDametis has allowed us to understand down to the kWh how much we consume compared to our production, or even how we consume when we are idle.”

MyDametis, a Tool to Identify Energy-Intensive Areas

“76% of LEDs have already been installed. The software estimates savings at around €100,000 per year.”

Another important observation identified with the MyDametis energy management platform is the proportion represented by lighting: 70% of the total consumption of one of their buildings. A simulation was conducted and estimated a 30% reduction if the entire building is illuminated with LEDs.

Mr. Mebtoul adds, “After analysis by Dametis, it was more than convincing to replace our energetically obsolete system with LEDs; we did everything ourselves, and in a month, 76% of the LEDs have already been installed. The software estimates savings at around €100,000 per year.”

MyDametis also highlighted actions that, when combined, represent a 15% reduction in consumption. Among these: regulating air leaks, readjusting compressors, turning off idle equipment.

Dametis Expertise, to Support Energy Sobriety Plans

Additionally, Dametis experts have supported an energy sobriety plan with “common” actions for all company employees: opting for equipment charging at night, running the hot water tank during off-peak hours, renewing signage to raise awareness about turning off lights, turning off computers and not leaving them on standby, and many more.

“In the long term, we would like to continue improving our Fatal Energy Project started in 2021 to reduce our heating gas consumption and achieve -80% by 2023.”
