Siemens’ Gridscale X redefines system operations and agentic transmission planning
Siemens’ Gridscale X redefines system operations and agentic transmission planning
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.
“Gridscale X is the integral digital
backbone that bridges long‑term planning and real‑time operations to
enable true system operations,” said Sabine Erlinghagen, CEO of Siemens Grid
Software. “The platform can support self-developed applications, enabling
utilities to migrate their own applications onto Gridscale X to run and
scale them on a shared grid model, integrating their innovations directly into
system operations workflows. We are delighted that this has already been
deployed by Alliander in The Netherlands.”
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 percent to
100 percent, migrated 85 applications onto Gridscale X, and achieved a 30
percent leaner IT landscape. This demonstrates how a shared digital backbone
can unlock grid capacity, reduce complexity, and scale at speed.
Gridscale X PSS E: Unlocking the future of agentic transmission planning
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.
“For more than 50 years, PSS E has been
widely regarded as the benchmark for transmission planning, trusted by planners
around the world,” added Erlinghagen. “We are incredibly proud to build on that
foundation with the next generation of PSS E. By introducing AI‑powered,
agentic capabilities and a modern user experience, we are giving planners the
tools they need to tackle growing complexity, work faster under increasing time
pressure, and lead the next era of transmission planning with confidence.”
