Following the completion of testing, Italian cabling giant Prysmian revealed it was ready to launch the new global standard for high voltage direct current (HVDC) submarine cable systems qualifying the use of 525 kV cables at an increased operating temperature of up to 90°C.

Founded on the higher withstand temperature of the cable plastic insulation while operating, this means that the maximum power that can be transmitted through a single 525 kV link increases from the current standard of 2 GW to 2.5 GW, and this power can already be deployed in the existing HVDC network infrastructure with no impacts on the rest of the system.
