India’s first private sector high voltage direct current (HVDC) power transmission system has been completed by the Adani Group and dedicated to the nation.
The line will carry power from the coal fired thermal electricity generated at Adani Power’s Mundra plant in Gujarat to Mohindergarh in Haryana which will be having the distance of around 1,000 km.
As said by Adani Power, the line is at 500 kV and will be having a 2,500 MW of transmission capacity.
The transmission line, completed in 24 months, passes through Gujarat, Rajasthan and Haryana and will start power supply to Haryana soon.
The power will first be transmitted from Mundra to Dehgam via a 400 kV, 430 km long transmission from where it will be transmitted to Mohindergarh using the newly constructed transmission line.
APL is also developing a dedicated 50-km 400 kV Mohindergarh-Bhivani transmission line for supply of power to the Haryana Power Generation Corporation Ltd (HPGCL), a company official told Business Line.
On an average, laying of one-km-long transmission line costs around Rs 5 lakh. Thus, the company invested nearly Rs 50 crore on the HVDC line. Besides, Adani Power Maharashtra Ltd (APML), a subsidiary of APL, is developing a 221-km, 400 kV Tiroda-Warora transmission line as an intra-state transmission licensee to evacuate power from APML’s Tiroda power project.
APL, having a target to generate 20,000 MW by 2020, is currently implementing 16,500 MW of power generation projects. At various stages of implementation are its projects at Mundra (4,620 MW), Bhadreshwar (3,300 MW) and Dahej (2,640 MW) – all in Gujarat – Tiroda (3,300 MW) in Maharashtra, Kawai (1,320 MW) in Rajasthan and Chhindwara (1,320 MW) in Madhya Pradesh.
The company had synchronized the first supercritical thermal power unit of 660 MW at Mundra in December 2010. APL's Mundra facility comprises five units of 660 MW (total: 3,300 MW) and four units of 330 MW (1,320 MW). All five supercritical units of 660 MW have been designed according to the energy efficient and environment-friendly supercritical technology, an official said.
APL had entered into long-term (25 years) power purchase agreements (PPAs) with the State electricity utilities for supplying a total of 7,144 MW. They included Gujarat (2,000 MW), Haryana (1,424 MW), Maharashtra (2,520 MW) and Rajasthan (1,200 MW). However, due to sharp increase in coal prices, the company is making efforts to have these PPAs revised.
