DNO Application & Notification Process for EV Chargers & Vehicle-to-Grid (V2G) Chargers
Installing an Electric Vehicle (EV) Charger or a Vehicle-to-Grid (V2G) Charger requires a formal notification or application to the Distribution Network Operator (DNO). This ensures the safe integration of charging systems into the electricity grid, avoiding overloads and maintaining network stability.
What is a DNO Application or Notification for EV Chargers & V2G?
The process for installing an EV charger or V2G system depends on:
Charger size and power rating
Single-phase vs. three-phase supply
Impact on local grid capacity
Two main processes apply:
G98 Notification – for small-scale, low-impact EV chargers (≤13.8kW single-phase)
G99 Application – for higher-power chargers (>13.8kW single-phase, three-phase systems, or V2G installations)
What’s Required for an EV Charger or V2G Application?
Installer & Customer Details
Company name & industry accreditation (e.g., OZEV-approved installer, NICEIC certification)
Installer and customer contact details
Site address & property details
System & Connection Details
Charger make & model (e.g., Tesla Wall Connector, Myenergi Zappi, Andersen A2)
Charging capacity (kW rating)
Single-phase or three-phase connection
Export capability for V2G chargers (bidirectional charging details)
Existing electrical load & maximum demand calculation
Technical Documentation
Wiring diagram & charger installation layout
Load assessment & impact study (if required by DNO)
Earthing & protection details
DNO application form (specific to network operator)
Application Submission & Fees
G98 Notification (Up to 13.8kW, Single-Phase)
Notification to the DNO after installation
No formal approval required pre-installation
Typically no application fee
G99 Application (Above 13.8kW or V2G Systems)
Pre-installation approval required from the DNO
More detailed assessment required
DNO application fees apply
Processing time: 30-60 days
What Happens Next?
Once submitted, the DNO will:
Assess the impact on the local grid
Approve the connection or request additional assessments
Recommend any required grid upgrades (for high-demand or three-phase chargers)
Once approved, installation can proceed
A commissioning report may be required post-installation
