New Cable System Doubles Power Flow, Hopes to Make Grid More Feasible

ABB unveils innovation to increase green energy efficiency

Swiss engineering group ABB has developed technology that can double the power flow of underground cables, making it cheaper to integrate electricity into the grid from distant offshore wind farms.

The innovation means a single high-voltage direct current (DC) cable can now transmit up to 2.6 gigawatts (GW) of power — enough energy to power two million homes, or serve the electricity needs of Paris, ABB said on Thursday.

Being able to pump more power through underground cables should make it easier to transmit electricity through densely-populated or environmentally-protected areas and even reduce the need for unsightly overhead power lines, said Claes Rytoft, ABB’s chief technology officer.
