In March 2025, Salt River Project commissioned the first confirmed production deployment of virtualized line differential protection using Routable Sampled Values over MPLS WAN, with ABB SSC600. The WAN-connected virtualized relay proved both faster and more consistent than a conventional microprocessor relay on direct fiber.
On 24 September 2025, NamPower commissioned Sekelduin — a 132/66/33 kV indoor switching station near Swakopmund, Namibia, built by ACTOM as Africa's first fully digital substation with IEC 61850 process bus end-to-end.
ENTSO-E's 472-page final report on the April 28, 2025 blackout in Spain and Portugal identifies systemic failures in voltage control, protection settings, and distributed generation visibility — not a single technology — as the root causes of the largest European grid incident in over two decades.
The 11th International Exhibition on Electric Power Equipment and Technology and its twin show, the 10th International Exhibition on Electrical Equipment.
ABB has teamed up with India’s national electricity grid operator Power Grid Corporation of India Limited (POWERGRID) in a mega project worth over $640 million for ABB to deliver a transmission link that will have the capacity to bring reliable electricity to more than 80 million people. The Raigarh-Pugalur 800 kilovolt (kV) ultra-high-voltage direct current (UHVDC) system will connect Raigarh in Central India to Pugalur in the southern state of Tamil Nadu.
