Electric Vehicle Integration
This initiative is intended to inform actions the OEB may take to ensure the efficient integration of electric vehicles (EVs) with the electricity system.
As part of the Electric Vehicle Integration (EVI) initiative, the OEB completed an analysis of the impact delivery costs have on EV charging service providers and owners of EV fleets. Alternative delivery rate designs are being explored to determine how they may support EV adoption while adhering to sound ratemaking principles. Distributed Energy Resources (DER) Connections Review Issues related to EV connection processes & requirements and system readiness are being reviewed through the DER Connections Review subgroup on EV charging connections. Ultra-Low Overnight (ULO) Price Plan This new price plan supports shifting electricity use to overnight when provincewide electricity demand is lower, supporting the integration of EVs. |
