At the Auto Sector Nashik plant two paint shops accounted for 100% of the thermal energy & approximately 60% of the electrical energy consumption of the entire plant. To make the plant more energy efficient a plethora of activities were initiated. These include: ranging from internal & specialised external audits, CAPA on audit, energy week celebrations, knowledge sharing seminar & platforms and energy conservation awareness programs.
