Explain the role

Power is an important factor for the location of heavy industries in India because no heavy industry can function without a good, uninterrupted power supply. Without a good, uninterrupted power supply, no production unit can run and thus no output production would take place. Certain industries like aluminium are located near the power source because they require huge quantum of electricity regularly to function.

Industries which use weight-losing raw materials are located near the sources of raw material. For example, the sugar industry is located near the sugarcane producing areas. This happens mainly because raw material can be easily transported to the industries before they perish out. Also, being located near the raw material source reduces the cost of transporting raw materials from the source to the industries.
