HVDC revenue to hit $56bn by 2020

Cumulative revenue from HVDC converters will reach $56.6bn between now and 2020, says analysis published today.

The report says that increased use of high voltage direct current transmission is being driven by growth in electricity demand, transmission system congestion and grid instability.

“Interest in innovative voltage-source converters (VSCs) has taken off, and demand for this technology is expected to grow,” states the study from Navigant Research in the US.

Kristoffer Torvik, senior research analyst with Navigant, said: “While AC transmission still leads the industry overall, VSCs have removed doubts concerning the limited capability of classic HVDC transmission.”

“HVDC allows interconnection of regional systems that operate asynchronously, which mitigates many instability issues that otherwise would cause outages in AC transmission.”

According to the report, approximately 333 GW of new HVDC transmission capacity will be added between 2013 and 2020.à‚ “In China alone, nearly 200 GW of new HVDC transmission capacity is planned for build-out over the next eight years.à‚  Energy from hydroelectric generation in distant inland locations will be tapped and transported to power big cities along the eastern and southern coast.”
