ABB has announced a new 525 kV extruded high-voltage direct current (HVDC) cable system that the company says can help make renewable energy installations more efficient and better accessible to distant utilities.
According to ABB, the new cable offers a 64% power increase over 320 kV, currently the highest voltage deployed for this type of technology. The company claims this latest system will more than double the power capacity to about 2.6 GW from 1 GW. It will also expand the cable's reach to distances of 1,500 km, up from less than 1,000 km, while keeping transmission losses under 5%, the company adds.
The 525 kV cable system can be deployed in subsea and underground applications, thus enabling countries and utilities to integrate more renewable energy being generated by distant solar and wind installations, including offshore wind farms.
"This major technology breakthrough will change the feasibility of renewable energy projects and play a defining role in using underground and subsea high-voltage cables to integrate renewables over long distances," says Ulrich Spiesshofer, CEO of ABB.
