The Appellate Tribunal for Electricity (Aptel) has ruled in favour of the Tamil Nadu Generation and Distribution Corporation Ltd. (Tangedco), setting aside an order issued by the Central Electricity Regulatory Commission (CERC) that declined to consider the Raigarh-Pugalur-Thrissur High Voltage Direct Current (HVDC) transmission corridor as an asset of strategic and national importance.
The Power Grid Corporation of India Limited is implementing this transmission corridor at a cost of about ₹20,000 crore to facilitate the transfer of surplus power from Raigarh in Chhattisgarh to the southern region. It is also a part of the green energy corridor for the transfer of renewable energy from southern States to the rest of India.
