Project Status
Project Update
The project officially commenced in November 2025 and is currently preparing a preliminary analysis of deliverables. The team is actively recruiting Technology Advisory Committee (TAC) members to advise on the project and has begun initial planning for EV submetering hardware and software development.
The Issue
EV submetering at residential homes can help simplify access to EV-specific rates and programs that benefit customers and the grid. However, current EVSE-based submetering solutions require prohibitively expensive hardware ($1,500-2,500), costly installation ($1,000-2,000), and EV chargers can trigger mandatory panel upgrades ($2,000-6,000), creating combined entry costs of $4,000-10,500. The lack of participating residential Meter Data Management Agents (MDMA) and deferred approval of telematics-based submetering approaches also contribute to systemic barriers preventing customer access to residential EV submetering solutions.
Project Innovation
This project will deliver an integrated, modular solution addressing barriers to adoption of low-cost residential EV submetering solutions. First, a multi-pathway measurement framework will be developed to meet the CPUC's mandated accuracy standards (±1% laboratory / ±2% field) through complementary pathways functioning independently or together: CDFA-DMS compliant Circuit Pauser direct circuit metering, precision CT clamp meter monitoring, integrated vehicle telematics from multiple EV manufacturers, and OCPP/API EVSE data streams. Second, an integrated MDMA platform will embed all CPUC-mandated functions, including required data retention (30 days onsite/90 days remote), utility-specific energy data formatting for California IOUs, and comprehensive dispute resolution processes. Third, a grid-interactive architecture will combine precise submetering with code-compliant intelligent load management that automatically prevents panel overloads, eliminating costly panel upgrades for homes with limited capacity.
Project Goals
Project Benefits
The project will deliver ratepayer benefits by reducing EV submetering implementation costs and simplifying access to rates and programs that shift charging load to support the grid.
Equity
Ensures equitable access to EV adoption benefits and EV-specific utility rates in low-income and disadvantaged communities where traditional submetering solutions remain economically inaccessible due to prohibitive costs. At least 50 percent of pilot deployments will be conducted in disadvantaged communities.
Affordability
Reduces total submetering implementation costs through an innovative multi-pathway architecture.
Reliability
Enables low-cost residential EV submetering, which will allow more customers to shift their EV charging load in response to EV-specific rates, dynamic rates, or programs and contribute to grid reliability.
Consumer Appeal
Provides a seamless, user-friendly solution requiring no behavior changes from homeowners while automatically optimizing charging schedules based on utility rates and renewable energy availability. Eliminates the need for expensive networked charging equipment while delivering a comprehensive mobile app experience for monitoring energy savings, charging patterns, and environmental impact.
Safety
Implements cybersecurity protocols with secure data exchange using preferred authentication methods and compliance with IOU-specific requirements.
