The average specific power consumption of the case study plant was 111 kWh/ton of cement with an aver-age peak demand of 9.7 MW. The high cost of electric power at 0.14 USD/kWh results in very high cost of production that significantly lowers the company's profit margin and limits its competitive advantage.
