Production Planning Using DayAhead Prices in a Cement Plant. Turgay Emir, Mehmet Güray Güler, in Exergetic, Energetic and Environmental Dimensions, 2018. Abstract. Cement production is an energyintensive process. The cost of energy constitutes more than 60% of the cost of the cement; hence cement plants have to consider minimizing the cost of energy when planning production.
