Aligned with their mission to optimize grid reliability and quality and ensure sustainable power, Belgian national electricity transmission operator Elia is continually exploring digital technology and workflows for infrastructure development and asset management. This project focuses on transitioning their obsolete drawing file management system and engineering processes to a centralized digital platform and smart digital workflows. Elia needed an integrated technology management and digital twin solution that included reference file support (BS 1192) and intelligent connections, as well as improved hand-off with third parties.Elia selected ProjectWise as their file management system, optimizing accessibility and traceability for more efficient planning management, estimated to save up to EUR 150,000 per year. Using OpenUtilities Substation and iTwin enables efficient substation design, lightening protection and controls, clash detection, visualization, and digital analysis via hybrid modeling and digital twin simulation, which is expected to save 30,000 resource hours annually. Bentley’s collaborative technology facilitates intelligent engineering and effective management workflows.
