High-Voltage Direct Current (HVDC) transmission technology is a crucial technology holding potential to disrupt the power transmission landscape of the world. This technology is at the forefront of the emerging "smart grid" revolution and has emerged as an economically-viable solution for bulk and long-distance power transmission. Various countries are adopting HVDC, due to its cutting-edge features over HVAC, such as long-distance transmission, asynchronous transmission, ease in controlling the active power link, the possibility of bulk power transmission, and low loss (typically 30-50% less transmission loss than comparable alternating current overhead lines) in the transmission of power.
The increasing demand for cost-effective solutions for long distance power transmission, ease in controlling the active power link, the possibility of bulk power transmission, and low loss in transmission of power (over HVAC) are some of the significant factors that drive the HVDC transmission systems market.
The EU, power generation mix, is expected to change considerably in favour of renewables over the next few years, with countries such as Germany, Spain, Belgium and France increasingly moving towards low carbon economy. The European Union has several policies in place, such as the EU's Renewable energy directive and national renewable energy action plans that support the transition to a low carbon energy system. Offshore wind power remains heavily concentrated in a small number of countries in the European region, with the majority (approx. 98%) of it in UK, Germany, Denmark, the Netherlands and Belgium. According to WindEurope, Europe had installed 3.1 GW of new offshore wind power capacity in 2017, out of which Germany accounted for 1.3 MW.
With increasing integration of renewable energy sources, and growing need to enhance the security of supply, HVDC grid technology is expected to evolve in the region. Moreover, increasing investments in offshore wind industry, solar photovoltaic, grid expansion and energy storage projects as well as the implementation of smart energy infrastructure will be necessary for the country to balance the fluctuating supply of renewable sources, thereby increasing the scope for HVDC transmission systems.
HVDC electricity transmission has become a key enabler of the emerging single energy market of 34 interconnected European countries. In addition, the countries of the European Union are working together to transfer renewable energy across borders, including links between Belgium and the UK, Norway and Germany, Germany and Belgium, Germany and Denmark.

Australia, a vast continent with low population density, is a net energy self-sufficient country rich in energy resources, from fossil-based to renewable energy. Although coal and natural gas account for major share of electricity generation in Australia, the country plans to retire approximately 63% of the existing coal generation fleet may retire by 2036. Furthermore, Australia has signed numerous environment agreement such as the COP 21 Paris agreement to increase the share of renewables in its energy generation mix.
The country has witnessed the large-scale implementation of renewable energy projects in the recent years, which are located at far off places, and needs to be grid-connected. Therefore, the growing share of renewables in the country is expected to significantly supplement the demand for HVDC transmission systems in Australia as most of the renewables projects are located at far off places from the demand centres.
The major players include – ABB, Siemens AG, C-EPRI Electric Power Engineering Co. Ltd, General Electric, Toshiba Corporation, Mitsubishi Electric Corporation, Prysmian Group, amongst others.
