ChargePoint operator explores submetering benefits for electric vehicle cost savings

The California Public Utilities Commission (CPUC) held a pivotal workshop on April 17, 2025, focusing on submetering and telematics, which could reshape the landscape of electric vehicle (EV) charging in the state. Key discussions centered around cost allocation, energy savings, and innovative business models that could enhance the EV charging experience for drivers.

One of the primary outcomes of the workshop was the recognition of significant energy savings that could be achieved through submetering. Stakeholders emphasized the importance of fairly distributing these savings among site hosts, drivers, and Meter Data Management Agents (MDMAs). The consensus was that while MDMAs need to cover their operational costs and generate profit, the majority of savings should benefit drivers, making EV charging more affordable.

Participants also explored the potential for ChargePoint Operators (CPOs) to take on the role of account holders for submetering. This model would allow drivers to pay CPOs directly for their electricity usage, streamlining the billing process and potentially increasing profitability for CPOs. This innovative approach could not only simplify transactions but also enhance the overall efficiency of the EV charging ecosystem.

The workshop highlighted the enthusiasm from various sectors, including fleets, educational institutions, and commercial real estate, all eager to adopt submetering solutions. Stakeholders expressed a commitment to exploring partnerships with MDMAs to expedite access to these technologies.

Looking ahead, the discussions underscored the need for submetering to align with existing programs, such as solar energy and flexible pricing initiatives. This integration could maximize the benefits of submetering, creating a more sustainable and cost-effective charging infrastructure.

As California continues to lead the charge in EV adoption, the outcomes of this workshop signal a significant step toward enhancing the accessibility and affordability of electric vehicle charging for all residents.
