Remediation

Hydro-Québec has updated the majority of charging stations to disable OCPP, mitigating the risk of exploitation. Hydro-Québec has also implemented authentication systems to mitigate the issue for certain charging stations which are still reliant on OCPP. Contact Hydro-Québec with any additional questions.
