This solution was implemented at a printing factory that produces disposable plastic lunch boxes for Chinese high-speed trains. Previously, production was dependent on electricity from peak periods, and since the factory was only active during the day, the average electricity price was around 0.90 DKK/kWh.
After installing our system, which stores electricity purchased during the night, the factory was able to utilize cheap energy for later use. The result was a reduction in the electricity price to approximately 0.30 DKK/kWh, which means that operating costs are now only a third of the previous level.
The investment was repaid in just 9 months.
