Building a Flexible Grid: VGI, Policy, and the Path to Electrification

Building a Flexible Grid: VGI, Policy, and the Path to Electrification


The VGIC EVolve Annual Member Meeting event provided a comprehensive look into the future of vehicle-grid integration (VGI) from regulatory, utility, and energy and automotive industry perspectives. Here are some of our team’s key takeaways from the discussions:

  1. Policy and Regulatory Frameworks Are Evolving to include Advanced Rate Design

    Regulatory agencies like the California Public Utilities Commission (CPUC) and other agencies, such as the CEC, are laying the groundwork for unlocking load flexibility through dynamic rates and Vehicle-to-Grid (V2G) integration. The CalFUSE rate design framework and the CPUC’s Demand Flexibility Proceeding aim to unlock societal benefits through flexible energy management to help California meet its grid reliability and decarbonization goals. 

  2. V2G and V2H: Potential Game Changers for Resilience

    Panelists noted that V2G technology can offer significant value, especially for residential customers in high-risk areas where blackouts are common. Customers using EVs for home backup power (V2H) can offset their home load and save on electricity costs, although technical challenges such as panel upgrades need to be addressed. Automakers and utilities are focusing on lowering these barriers, which could help avoid a shift back to internal combustion engine (ICE) vehicles.

  3. Customer Experience and Economic Viability Are Key to Adoption

    Automakers like Ford stressed the importance of creating a seamless and cost-effective experience for customers. V2G and managed charging must provide clear economic benefits to customers to make EVs more attractive than traditional ICE vehicles. Simple, intuitive programs will be essential to achieving mass adoption. Managed charging programs are often seen as "low-hanging fruit" for utilities, offering an accessible starting point for many customers.

  4. Grid Capacity and Infrastructure Challenges

    Utilities face significant challenges when planning for VGI integration and meeting customer needs, particularly with energization timelines,  load management, and distribution system planning. There is a growing need for utilities to consider future electrification needs in their planning processes, with solutions like Automated Load Management (ALM) technology, flexible service connections, limited generation profiles, and Virtual Power Plants (VPPs) being part of the mix. However, utilities must also work faster to meet the electrification goals of various sectors, from drayage fleets to residential customers. Utilities such as Southern California Edison (SCE) are also testing ALM solutions through their Load Constraint Management System (LCMS) pilot, which allows load growth customers to interconnect in a capacity constrained area using ALM technology. This system will allow participating customers to interconnect their EV load while waiting for additional capacity to become available.

  5. Data, Visibility, and Market Fragmentation

    Accurate data is essential for managing grid flexibility, and the California Independent System Operator (CAISO) needs more visibility into VGI activities to improve their forecasts and avoid over-procurement. Market fragmentation, particularly between automakers, utilities, and third-party aggregators, could become a major barrier to progress. Improved collaboration among these players and developing open-source solutions will be crucial for scaling VGI.

  6. Managed Charging: Simplicity and Accessibility

    Managed charging programs are seen as an important way to meet emissions reduction targets, especially as utilities like Xcel Energy look to build up dispatchable capacity and unlock more load flexibility. The design of these programs must be simple to attract mass adoption, and there must be efforts to include disadvantaged and low-income communities in the transition.

  7. Cross-Sector Collaboration and Innovation

    VGI is highly cross-cutting, affecting the energy, utility, and automotive industries and requires a collaborative approach. The event emphasized the need for certainty in VGI’s role in utility planning and encouraged innovative solutions, like bidirectional charging, EV telematics, and leveraging EVs as distributed energy resources as part of VPPs, to address grid resiliency and decarbonization. Cross-sector engagement is critical to ensuring VGI can be a reliable tool for utilities and customers alike.

VGIC’s EVolve Annual Member Meeting underscored the importance of collaboration, innovation, and customer-centric program design in accelerating the adoption of VGI technologies and making electrification work for everyone. Stay tuned for more updates from our team!
