Powergridfully commissions India’s first VSC based HVDC system  

The Power Grid Corporation of India Limited (Powergrid) has commissioned Monopole-I of the ± 320 kV, 2000 MW, Pugalur (Tamil Nadu) – Thrissur (Kerala) Voltage Source Convertor (VSC) based High Voltage Direct Current (HVDC) system.

This project is India’s first VSC based HVDC system and it will enable transfer of 2,000 MW power to Kerala through the VSC HVDC station at Thrissur.The VSC technology significantly reduces the land requirement compared to the conventional HVDC systems and is particularly suitable for areas, where land is scarce. Monopole-II of the project was inaugurated February 19, 2021 and with the commissioning of Monopole-I, the project has attained its full capacity.The cost of the Pugalur-Thrissur HVDC system is about Rs 50.70 billion. It is a part of the Raigarh-Pugalur-Thrissur 6000 MW HVDC system.With amajor part of the design, engineering, testing and commissioning for the project has been done in India, it is aligned to the “Aatmanirbhar Bharat” scheme.
