plus Grid Stability & Virtual Inertia

Fast Frequency Regulation & Voltage Stabilization

Reliable Synthetic Inertia

As renewables share of the grid’s power supply increases, it introduces new risks due to their lack of inertia and fully current support. E-STATCOMs emulate traditional rotating mass to stabilize low-inertia grids. 

  • Maintains grid frequency within safe limits.
  • Enables high renewable penetration.
  • Ideal for microgrids and isolated systems.
