Maintaining system stability in a low-inertia grid requires a new level of visibility
Real-time, location-specific insight into how inertia behaves across the grid.
“Digital technology plays a big role in energy transition. And technology like from Reactive, is giving our system operators real time information that can help to make better decisions in real time.”
Director of Board, CEN, Chile
Why inertia needs a new level of visibility
Power systems are becoming more dynamic, while overall inertia is declining, making frequency behaviour more sensitive and harder to manage.
At the same time:
- Substantial inertial support from behind-the-meter sources cannot be easily estimated or leveraged
- These contributions are variable and typically not directly measured
- System-level estimates do not reflect regional behaviour or local vulnerability
- This can lead to unnecessary action in both operational and planning timescales
Measuring real inertia, including these hidden contributions provides a clearer view of how stability is actually distributed across the grid.
