HVDC Global Project Specific Database: Installed base and pipeline projects segmented into LCC and VSC

High voltage direct current (HVDC) power systems use D.C. for transmission of bulk power over long distances. For long-distance power transmission, HVDC lines are less expensive, and losses are less as compared to AC transmission. It interconnects the networks that have different frequencies and characteristics. Voltage Source Controlled (VSC) HVDC and Line current commuted (LCC) HVDC technologies are the two main HVDC technologies that are deployed all across the globe. The HVDC interconnection is mostly deployed to integrate the renewables into the main grid.

The APAC HVDC market is expected to grow with CAGR of 5% from 2022 onwards till 2026. This projection is in line with the major transmission capacity expansion projects to cater to the growing industry and increasing load demand in the region's key countries. China and India have been the leading demand centers for HVDC systems in the area over the last decade, due to their growing demand for electricity and the trend of industrialization in their respective countries. China installed 205 GW of HVDC transmission capacity, India installed 20 GW of HVDC transmission capacity and South Korea installed 6.1 GW of HVDC transmission capacity from 2012-2021.

The HVDC market of the APAC region is largely driven by the transmission expansion plans of different countries that are moving to transmit power to demand centers over long distances. However, China and South Korea have deployed HVDC technology to integrate renewable energy generation with the power grid. HVDC technology is currently in the early stages of development in the region and in the upcoming years it is expected that the countries in the region (mostly underdeveloped countries) will deploy LCC HVDC technology instead of VSC HVDC because it is a cheaper technology.
