ABB Group and Power Grid Corporation of India Ltd (PGCIL) have started working on the India’s first green energy corridor project. Under this project, a power transmission link of 800 kilovolt (kV) ultrahigh-voltage direct current (UHVDC) system is to be constructed.
The 800 kV line will connect Raigarh in central India to Pugalur in the southern state of Tamilnadu over an area of 1830 km, would be among the longest in the world.
The project by state-run Power Grid Corporation of India (PGCIL) is being executed by ABB Group in partnership with Bharat Heavy Electricals Ltd (BHEL).
Significance of Raigarh-Pugalur Power Line:
1.The 800 kV line with a capacity of 6000 MW-equivalent to more than six large power plants, will have the capacity to meet the electricity needs of over 80 million people in India.
2. The two-way power link will integrate thermal and wind energy for power transmission to high consumption centres located thousands of kilometres away.
It will support energy demands in the south by providing thermal electricity from the grid, when wind strength is low, and transmit clean energy to the north when there is excess wind power generation in South India.
3. The power transmission line based on ultrahigh-voltage direct current system (UHVDC) is a development of high voltage direct current system (HVDC), which will occupy only one-third of space compared to the traditional AC (Alternating current) system.
Moreover, HDVC system transmits more power over long distances minimising losses.
What is Green Energy Corridor Project:
Green Energy Corridor Project aims at synchronising electricity produced from renewable sources, such as solar and wind, with conventional power stations in the grid.
The Government has decided to invest in this project to facilitate the flow of renewable energy into the national grid.
