Connect EV Chargers without Rebuilding the Grid
GridFlow keeps EV charger outputs within the limits of your existing grid. Connect significantly more chargers before any reinforcement is needed.
The Grid Was Not Built for Clustered Charging
Public EV charging is scaling fast, but the low-voltage networks carrying that load were built for a different era. Charging arrives concentrated and clustered – retail sites, depots – and it lands first on your weakest assets.
When multiple chargers draw power simultaneously, transformers and feeders can exceed their limits – causing voltage drops, tripped protection, and breaches of power-quality obligations (e.g. EN 50160).
Today that leaves three responses, and all three are expensive:
Reinforce
Dig, lay cable, replace transformers. Slow and capital-heavy.
Refuse or Delay
Turn down new connections. Customer and regulatory pressure follows.
Hope It Holds
Run assets past their limits. Outages, degradation, and voltage problems follow.
Headroom under the transformer changes hour by hour.
GridFlow measures it continuously and adjusts charger setpoints to match.
What is GridFlow
GridFlow is an autonomous control system for EV charging sites, built on dynamic load management. It continuously monitors the grid, predicts potential stress points, and automatically limits charger output to stay within safe operating limits.
It is built to serve charging demand as fully as the grid allows. Charger output comes down only in the intervals where capacity runs short, and only by as much as needed. Charging is shifted within the available headroom – nobody is turned away, and every vehicle still charges.
How GridFlow Helps
Connect More Chargers on the Same Network
Significantly more chargers fit on your current network. Smart charging defers or avoids costly grid reinforcement, and reliability and power quality hold.

Decide How Capacity Is Shared
Give high-value locations more, constrain others, and combine predictive scheduling with continuous real-time control. You set the policy, GridFlow enforces it.
Stay within Limits
Overloads, voltage drops, and tripped protection are caught early, whether anticipated in advance or arising suddenly. Proactive scheduling and a continuous real-time safety net keep your network within its power-quality limits.

Ask Your Network Directly
Ask the built-in AI assistant “what drove last week’s load spike?” and it answers in plain language within seconds. Nobody has to write a query or wait for an analyst.

Built for National Critical-Infrastructure Environments
The OT device stack is hardened in line with ISA/IEC 62443 – zone and conduit segmentation, deny-by-default firewall rules, secure remote access through a VPN boundary, and security event logging.
Not Sure How Your Low-Voltage Grid Is Connected?
GridMapper reconstructs the supply tree from smart meter data – which delivery point sits on which feeder, secondary substation, and phase.
How GridFlow Works
Reads the Grid
Measurements from the secondary substation, combined with smart meter data, give a real-time picture of the load beneath each transformer.
Predicts Risk Windows
A self-learning model calculates grid behavior with and without charging demand, and identifies the periods where capacity runs short – flagging, for instance, that charger output needs to come down between 2:00 and 3:00 PM.
Controls Charger Output
Over OCPP, GridFlow instructs each charger in advance and in real time, adjusting output as grid conditions change – e.g. “limit charger A to 80% in two hours.” Nobody in your control room has to step in.
Protects Locally
GridFlow curtails charging automatically in response to frequency and RoCoF excursions. Where an Edge Control Unit is installed, it makes that decision on site, independently of the cloud connection.
Records Every Action
Dashboards show site loading, headroom, constraint violations, and power-quality KPIs. Every curtailment and alarm is logged with who, what, when, and why, and reports export for compliance.
Four Levers at the Delivery Point
GridFlow solves each constraint with the gentlest lever first, and escalates only when needed.
Tariff
A price signal shifts charging to off-peak hours on its own.
Limiter
Caps power draw at the delivery point to prevent local overload.
Relay
Switches loads for balancing and congestion prevention.
Direct Communication
Instructs the charger over OCPP to reduce or pause in real time.

Edge
Optional. We can supply an Edge Control Unit at the charging site’ s connection point, with a Secondary Substation Kit at the LV bus and an EV Charging Site Kit at each controlled charger’s point of common coupling. With it, protective actions run on site, independently of the cloud connection. Without it, GridFlow works with the data and devices you already have installed.

Cloud
Telemetry, prediction, dashboards, and reporting. Runs in your private cloud environment, including your own Azure tenant, or fully on-premise.
Works with the Systems You Already Run
GridFlow connects to the chargers, meters, and control systems on your network.

Read and set through your metering and RTU
interfaces – DLMS/COSEM, Modbus, IEC 61850.
Operator Systems
Integrates with SCADA, ADMS, and meter data management.
