Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ā¹43,559 crore at the end of March 2021 compared to the companyās market capitalisation of ā¹44,447 crore.
