This was one of the fastest investment return in all of our projects. This client was a printing factory making plastic disposable lunch box for Chinese’s high speed trains. They used to dry the paint with peak power and as they only work in day time instead of 24 hours, their average electricity price is very high around 0.9 Yuan/KWH. After they use our product and only use off-peak power which cost only 0.3 Yuan/KWH their running cost is only 1/3 of which it used to be.
They spent 1.8 million Yuan on this project and the government gave them a 0.5 million compensation for demand side response as grid in that reign is trying to balance their capacity. So, they got all their investment back in 9 months.
