ABB has secured contracts worth $300m to supply advanced converter transformers for two long-distance ultra-high-voltage direct current (UHVDC) transmission links in China.
The 800kV transmission links, 1,609km Ximeng-Taizhou and 1,231km Shanghaimiao-Shandong, have the capacity to transport more than 10,000MW of electricity. The transmission links are estimated to provide 25% more energy, compared with recent 800kV UHVDC links, via the same narrow transmission corridor.
ABB’s power grids division president Claudio Facchin said: "This latest breakthrough of transmitting 10GW of power over a single 800kV UVDC link underlines ABB’s next-level strategy of delivering innovative solutions for the integration of renewables and efficient bulk power transmission to urban centres.
"Our ultra-high-voltage technologies are enabling countries like China to transmit ever increasing amounts of power over greater distances, with minimal losses and uncompromising reliability."
The links form part of a project aiming to transmit power from Inner Mongolia through long-distance transmission lines. The country’s major load centres are located in eastern regions, while energy resources are located in the west and north-west.
Substantially slashing carbon emissions is an aim of the project, while also lowering sulphur dioxide and mono-nitrogen oxide emissions.
Due to increased demand in the last decade, the country is also planning to increase its UHV transmission capacity, allowing for the delivery of power from new thermal power generation plants near energy reserves, while reducing pollution near cities.
