The VSC HVDC system features four interconnected stations in a ring network and can transmit up to 4,500MW of clean energy.

The grid will also enable the integration of remote wind, solar and hydro energy in a transmission ring to ensure optimal power flow.

“ABB’s participation in this project reflects SGCC’s ongoing confidence in ABB’s proven HVDC expertise.”

ABB will supply several critical components, including an HVDC Light valve, transformer components, high-voltage capacitors and power semiconductor devices.

ABB Power Grids division president Claudio Facchin said: “ABB pioneered commercial HVDC technology more than 60 years ago and introduced crucial innovations like HVDC Light and ultra-high HVDC (UHVDC) transmission to ensure reliable and efficient power supplies.
