Relay protection, SCADA, Metering, and Cybersecurity for electrical infrastructure.
CIGRE's first dedicated framework for virtualised IEDs will not publish until Q1 2028 — but the vPAC pilots that have to align to it are being commissioned now. Its scope is already public, through the working group's Terms of Reference and a framework article refeatured in ELECTRA 345 (April 2026): what is mandatory, what is deliberately out of scope, and what every 2026 vPAC pilot should already be doing in response.
UK Power Networks' Constellation project replaces bay-level protection relays with virtualized software on substation computers, using IEC 61850 process bus for local protection and R-GOOSE over 5G for wide area coordination. The first site is operating in Maidstone, Kent, with five more planned across South East England.
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.
