In India, finish grinding typically consumes around 40 per cent of power while raw material preparation and clinker burning account for an additional 30 per cent. Therefore, an uninterrupted power supply is key to the smooth operation of any cement plant. To ensure such a supply, UltraTech Cement has recently commissioned captive power units at its Rawan, Rajashree and Andhra Pradesh works and is expanding its power provision with other forms of clean energy. By UltraTech Cement, India.
While average power consumption in Indian cement plants has fallen significantly over recent years (see Table 1), for consistent and cost-effective operations, the power supply must be continuous and uninterrupted. Therefore, most Indian cement companies operate captive power plants (CPP) which are supported by a grid connection from the state electricity boards and range from 7.5MW to
4 x 25MW, depending on the peak load demand.
