Delhi's High Court agreed on Wednesday to hear a petition by state-run power producer NTPC Ltd
The Central Electricity Regulatory Commission said last month that it would tighten incentive structures on capacity utilisation and tax treatments for NTPC, sending shares in India's top power producer down sharply to a five-year low.
Analysts predict that the new pricing structure will likely hit NTPC's earnings.
The High Court will hear the company's petition at the next hearing on May 19, NTPC said.
Shares in NTPC were up 0.2% at Rs 118.1 per share by 1330 IST, outperforming a flat S&P Sensex, the 30-share benchmark index.
