CIS Digital Power Systems: Russia’s Stability Margin Monitoring System Deployed for the First Time on Cross-Border Transit With Belarus
In December 2025, Russia’s System Operator of the Unified Power System and Belarusian state utility Belenergo commissioned a Russian-developed digital Stability Margin Monitoring System on the key cross-border power corridor linking central Russia and Belarus.
A Cross-Border Deployment
The project was implemented on three high-voltage transmission lines rated at 750 kV and 330 kV, forming a critical corridor for electricity flows between the two countries. This marks the first-ever international deployment of Russia’s grid stability monitoring technology and represents a milestone in the digitalization of power systems across the CIS.
At the core of the system is continuous, real-time calculation of the maximum amount of power that can be safely transmitted through the grid at any given moment. The calculations take into account actual generation loading, grid conditions, and overall system balance. Before the system was introduced, dispatchers performed such assessments in advance and for a limited number of scenarios. As a result, operators often built in excessive safety margins and were unable to fully utilize available network capacity.
The new system now automatically analyzes telemetry from both sides of the border in cycles of tens of seconds, providing Russian and Belarusian dispatchers with a shared, up-to-date operational picture. This enables higher utilization of the cross-border corridor without compromising grid stability. According to data from trial operations, the deployment has unlocked an average of about 100 MW of additional available transmission capacity.
Beyond capacity gains, the system improves reliability and operational flexibility. It allows more precise control of cross-border flows, simplifies the provision of mutual emergency assistance, and lays the groundwork for more efficient commercial electricity exchanges between the two countries.
IT Evolution and Export Potential
The successful launch opens up broader perspectives for Russian digital energy solutions. It demonstrates their readiness to operate in complex cross-border power systems. The Stability Margin Monitoring System could become part of an export offering for other CIS countries facing similar challenges related to transit optimization and grid resilience.
A logical next step in the system’s development is the integration of artificial intelligence and machine learning elements for predictive analytics, automated identification of optimal operating modes, and early prevention of emergency situations.
The experience of jointly tuning models and exchanging data between the Russian System Operator and Belenergo can be replicated elsewhere, supporting deeper cross-border integration of power markets and dispatching services across the CIS.
From Pilot Projects to an International System
International deployment represents a natural stage in the evolution of the Stability Margin Monitoring System. Developed domestically by JSC NTTS UES, a subsidiary of the Russian System Operator, the system has been rolled out across Russia since the early 2020s. Over the past five years, the digitalization of dispatch control has become a clear trend, shifting operations from preventive, manual calculations toward adaptive, dynamic grid management.
By the end of 2025, the system was already operating on more than 600 monitored interfaces within Russia’s Unified Power System, demonstrating both effectiveness and reliability. The Belarus project, initiated in September 2024 following decisions by the CIS Electric Power Council Commission, served as a testbed for cross-system interaction. The Belarusian side played an active role by supplying model data and real-time telemetry, laying the foundation for future shared operating standards.
Energy Security for Eurasia
The deployment of the Stability Margin Monitoring System on the “Center – Belarus” corridor is more than a localized IT project. It showcases the technological maturity of Russia’s digital power sector and represents a practical step toward building smart cross-border grids.
The project illustrates how digitalization can address fundamental challenges – improving the efficiency of existing infrastructure while strengthening energy security across Eurasia. By 2030, similar real-time monitoring systems could become standard across all critical transmission corridors, enabling economically efficient and technically reliable cross-border electricity exchange.
