The Aditya Birla group plans to invest Rs. 6000 crores in solar power over the next five years as demand for clean energy rises and the government's target of 20 gigawatts of solar energy by 2022. The group has acquired stakes in solar power ventures in Gujarat and Rajasthan, and plans to set up an independent solar power company to develop 100MW of capacity in the next 18 months. It has already invested over Rs. 200cr to develop 20MW of solar power capacity.
