Two prominent infrastructure companies belonging to Adani Group and Tata Group had sought the assistance of electricity regulators to hike the rate at which they sold power to several state power utility and distribution companies. They claimed that compensatory tariffs to the tune of nearly ₹8,000 crore were due to them as they had to absorb an increase in the price of coal imported from Indonesia used to fuel their power plants. But this was denied to them by the Supreme Court.
