As the oldest renewable energy resource, hydropower is well-established as a reliable source of dispatchable energy. Yet, it is often overlooked and taken for granted. It’s commonly believed that hydro’s

High-voltage power transmission systems are more important today than ever before because power generated at renewable energy sites in remote locations must often be transmitted to distant load centers. Several state-of-the-art projects being done around the world are reviewed below. The majority of major electric power transmission lines in the U.S. are 115-kV, 230-kV, or […]

The Department of Energy (DOE) has initiated a new “enabling” pathway to achieve and sustain a dramatic transformation of the nation’s evolving grid—through its power electronics fabric, with the realization of advanced semiconductor materials, devices, and power module technologies. The agency on Nov. 21 unveiled the agency’s first awards—$42 million for 15 projects across 11 […]

Canada Commits CA$3B to Complete Romania’s CANDU Nuclear Construction. Canada will loan CA$3 billion in available export financing to Nuclearelectrica S.A. (SNN), Romania’s state-owned operator of the

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, […]
