Siemens’ Gridscale X redefines system operations and transmission planning
- May 5, 2026
Siemens has announced the next evolution of its Gridscale X platform at the Grid Software Summit in Amsterdam.
Gridscale X provides the digital foundation for utilities to manage their grids at greater speed, and complexity at scale. Siemens also unveiled the next generation of PSS E on Gridscale X, introducing advanced AI-powered, agentic capabilities to the transmission planning software.
As utilities face rising demand and growing system complexity, both transmission planning and grid operations are being pushed beyond the limits of traditional approaches. Electrification, data centers, and AI-driven industries are scaling faster than anticipated, while renewables are injecting volatility that traditional grids cannot absorb. Meeting these challenges requires true system operations. A unified grid model and digital twin enables system-wide visibility to actively manage flexibility, reduce operational risks and operate grids closer to their technical limits with confidence – laying the foundation for autonomous, resilient grids.
Leaner IT landscape
Dutch network operator Alliander, a strategic partner of Siemens, is the first utility to integrate its custom-built applications directly into the platform. Since announcing the partnership in 2024, Alliander has expanded medium-voltage grid coverage from 65 per cent to 100 per cent, migrated 85 applications onto Gridscale X, and achieved a 30 per cent leaner IT landscape. This demonstrates how a shared digital backbone can unlock grid capacity, reduce complexity, and scale at speed.
Gridscale X PSS E
Extending the same platform and shared grid model principles into transmission planning, Siemens has taken a major step toward unlocking the future of agentic transmission planning, unveiling the next generation of PSS E on Gridscale X. The software introduces new AI-powered capabilities that deliver the speed, transparency, and scalability required for resilient, sustainable, and autonomous grids. By combining proven simulation with domain-specific AI-automation and a new user experience, the software accelerates planning studies and workflows, expands team capacity, and improves decision-making end to end. Supported by over 2000 open APIs with automation capabilities, Gridscale X PSS E enables seamless integration, powerful automation, and the foundation for digital twin-based planning.
The latest release directly supports data center and large load integration scenarios, enabling planners to assess, prioritize, and respond to connection requests with significantly greater speed and transparency. A redesigned, cloud-native user experience streamlines workflows and automation for connection studies, cutting response times by up to 50 percent and helping transmission operators manage surging demand while maintaining system reliability.
