Reactive Technologies and Siemens Revolutionize Grid Resilience with Integrated Edge-to-Cloud Inertia Monitoring

Reactive Technologies will use Siemens’ Gridscale X software, PSS®E, to enhance visibility of grid stability challenges

(IN BRIEF) Siemens Smart Infrastructure and Reactive Technologies have formed a strategic partnership to advance grid stability and enhance renewable energy integration. By combining Reactive Technologies’ GridMetrix®—which provides real-time, accurate grid inertia data—with Siemens’ Gridscale X software, specifically the PSS®E module, the partnership offers a cutting-edge solution to monitor and optimize grid performance. This integration enables grid operators to obtain a real-time view of inertia levels and system strength, critical for maintaining stability and unlocking additional renewable capacity. The enhanced system supports comprehensive network studies, precise grid modeling, and improved operational planning. Key executives from both companies emphasize that the collaboration provides actionable insights to mitigate risks, reduce renewable energy curtailments, and guide future investments, ultimately accelerating the transition to a low-carbon energy grid.

(PRESS RELEASE) ZUG, 20-Mar-2025 — /EuropaWire/ —  Siemens Smart Infrastructure has joined forces with Reactive Technologies, a leading innovator in Grid Enhancing Technologies (GETS), to accelerate the transition to a resilient, low-carbon power grid. In this strategic partnership, Reactive Technologies will integrate Siemens’ Gridscale X software, specifically its transmission planning module PSS®E, with its proprietary GridMetrix® technology. This integration is designed to enhance real-time visibility into grid inertia and system strength—key parameters for understanding and mitigating grid stability challenges. Accurately monitoring these factors allows grid operators to better manage power failures and unlock up to 30% additional capacity from renewable sources, reducing reliance on fossil fuels for inertia support.

The advanced solution enables operators to perform more precise network studies, optimize grid modeling, and improve both operational performance and strategic planning. By generating high-resolution, real-time data on the kinetic energy stored in generators, motors, and condensers, the combined system offers a comprehensive view of grid resilience. This facilitates detailed simulations of various grid scenarios, helping operators pinpoint current asset performance and determine where future investments should be targeted to enhance overall system stability.

Marc Borrett, CEO of Reactive Technologies, commented, “Power system simulations are a critical early-stage step in our R&D process. By merging our direct measurement capabilities with the robust simulation power of Siemens’ PSS®E software, we empower grid operators to obtain actionable insights that help mitigate risks, reduce curtailments, and plan renewable resource expansion.” Magnus Torronen, Head of Siemens Grid Software Northern Europe, added, “Reactive Technologies is proving its expertise globally. With PSS®E now integrated into our Gridscale X suite, we are better equipped to provide the high-quality, precise data that the market demands for future investment planning. Our collaboration is essential in driving the power sector’s swift transition to zero-carbon energy.”
