Low-voltage grids are flying blind.
The low-voltage grid was never designed for two-way power flows. As the energy transition accelerates, rooftop solar, EV chargers, and heat pumps are being connected to the low-voltage grid faster than it was designed to handle. Most DSOs have zero real-time visibility below the MV/LV transformer.
The result: voltage violations go undetected, hosting capacity is underestimated, and cable reinforcement decisions are based on assumptions rather than data.
- No real-time state insight below the transformer
- Hosting capacity determined by worst-case assumptions
- Cable reinforcement planned without actual load data
Low voltage grid visibility using a sparse sensor network.
Griddle is a low-voltage grid monitoring system that delivers full-network visibility from a fraction of the sensors. Install measurement devices on a small number of feeders. Griddle's state estimation engine infers voltage, current, and power quality across the entire low voltage network.
Precision Hardware
Rogowski coils and voltage probes sample at 8,000 samples per second, capturing up to the 80th harmonic.
Physics-Informed AI
Our PINN-based state estimator enforces Kirchhoff's voltage and current laws as hard constraints, not learned approximations. Accurate voltage and current estimates at every node, even those without a sensor.
Actionable Output
Dynamic Operating Envelopes are computed at the edge, in real time, using live network state rather than static grid models. Connected assets get a DOE that reflects actual network conditions: tighter when the grid is stressed, more generous when it isn't.
Built for the grid, not the cloud.
Griddle runs inference at the edge. No cloud round-trips, no latency, no dependency on connectivity for critical calculations.
