Frequently Asked Questions (FAQs)
1. How is high voltage direct current transmission market performing at global level?
High voltage direct current transmission market is estimated to worth around USD 14.6 billion in 2026 and is forecasts to reach around USD 21.7 billion by 2033 growing at 5.8% CAGR. Large-scale renewable integration, long-distance power transmission needs as well as grid stability requirements are bolstering high voltage direct current transmission market.
2. Why HVDC being preferred instead of AC for new power lines?
HVDC is like a highway with no speed limit. In AC increase in the length of the grid line results in loss of power supply. HVDC eliminates these losses, meaning operator can send more power, further, using thinner wires and fewer towers. Over distances of 600km or above, HVDC is cheaper and more efficient.
3. How does the current U.S. political environment impact high voltage direct current transmission market?
The current administration’s focus on energy dominance and lowering electricity bills favours HVDC. By moving bulk power from areas with an energy surplus to areas with an energy deficit (like the Mid-Atlantic PJM region), HVDC helps prevent blackouts and lower wholesale prices, fitting the administration’s energy independence narrative.
4. Is VSC better than LCC technology?
LCC is suited for high-power, long-distance transmission, while VSC offers greater flexibility and is ideal for offshore wind and weak grids. LCC is a better option for moving 10 GW of power across a continent at low cost. VSC is the precision option, smaller, smarter and can operate in weak grids or offshore, making it preferred choice for modern Smart Grids and renewable integration.
5. Can HVDC lines be buried underground?
Yes, and it is a major selling point. Unlike AC, which has high magnetic interference and heat issues underground, HVDC cables can be buried for long distances. This is a differentiator for getting power into dense cities like New York or London where one cannot build new overhead towers.
