HVDC

The 19th century battle between Nikolai Tesla’s alternating current (AC) and Thomas Edison’s direct current (DC) technologies had an undisputed winner. The vast majority of the world’s transmission and distribution grids work now on AC. But DC—and high-voltage direct current (HVDC)—is attracting renewed interest. New Applications Emerge for HVDC The benefits of HVDC include its […]

European Grid Operator Secures 22 GW of HVDC Projects. European transmission system operator (TSO) TenneT will lead a charge to install 11 2-GW high-voltage direct current (HVDC) systems by 2031. A long-term

Hitachi Energy has been chosen by TenneT, a transmission system provider for Germany and the Netherlands, to supply several onshore and offshore high-voltage direct current (HVDC) converter stations and associated infrastructure for European power grids. Hitachi officials on March 30 said the agreement, which includes Petrofac—an international service provider to the energy industry—is worth about […]

Hitachi Energy will spearhead the modernization of a key high-voltage direct current (HVDC) system in Canada to support the transmission of 1,500 MW of renewable power between Quebec and New York state’s electrical networks. Hydro-Québec, Canada’s largest power utility, on Dec. 15, picked the global technology firm to supply a “back-to-back” converter station at Châteauguay, […]

Significant advances in high-voltage direct current (HVDC) transmission are in step with rapid changes to energy systems worldwide. Shortly after POWER magazine began publication in 1882, the competitive

Power networks today face two major challenges: aging infrastructure and complex intermittent power flows caused by the worldwide transition from fossil-based fuels to zero-carbon resources. With some of the

Greenlink interconnector will increase power supply security and foster the integration of renewable energy Consortium of Siemens Energy and Sumitomo Electric to supply HVDC cable and converter technology Siemens Energy, together with its consortium partner Sumitomo Electric, have signed a contract with Greenlink Interconnector Limited. Siemens Energy will deliver the high-voltage direct current (HVDC) converter […]

Everyone in the power industry is familiar with Siemens Energy. Its technology is behind about one-sixth of the world’s power generation, and even a larger portion than that in the U.S.—roughly a third. Yet, Siemens Energy as currently organized is a fairly new entity. The company was spun off from Siemens AG and began trading […]
