In a landmark move that will fundamentally reshape Brazil's green energy infrastructure, State Grid Corp of China has broken ground on a 1,468-kilometer ultra-high voltage power superhighway, marking the largest electricity transmission investment in the South American nation's history.
The massive 800-kilovolt direct current transmission line will serve as a vital energy artery, channeling bundled wind, solar and hydropower from Brazil's resource-rich northeast directly to major central and eastern load centers, it said.
Independently invested, constructed and operated by State Grid's Brazilian subsidiary under a 30-year concession agreement, the megaproject leverages China's mature UHV technology.
UHV transmission lines refer to power transmission cables operating at voltages exceeding 800 kV of direct current or 1,000 kV of alternating current.
Scheduled for full operation by 2029, the project, in addition to the nearly 1,500-km transmission line, features two newly built converter stations and related supporting facilities, and boasts a rated transmission capacity of 5 million kilowatts, it said.
