2025 in Review: More Products, Clearer Rules, Better Deployment Models
By Zach Woogen
As 2025 draws to a close, one thing feels unmistakably different than even a year ago: vehicle-grid integration (VGI) solutions are no longer confined to pilot programs and conference breakouts. The topic is showing up in national headlines, in utility program application budgets totaling tens of millions of dollars, and – in the case of bidirectional charging systems – in more products customers can buy and use today.
Amid these high notes and a year of shifting tides for overarching EV topics, VGIC’s vision remains unchanged: making it possible (and normal) for EVs to charge and discharge in ways that support both customer needs and a reliable, affordable, and efficient electric grid. What has changed is the momentum behind that mission.
Below is a quick look back at what moved forward in 2025 and a preview of what VGIC is preparing for in 2026.
2025 in Review
1) VGI concepts broke beyond the “insider” crowd and into mainstream media
This year, VGI began to break through in a significant way at the nation’s most prominent outlets, including the New York Times, Wall Street Journal, Washington Post, USA Today, and other forums for public discourse, with references from Governors, State Commissioners, and political pundits. The conversation is shifting from “is this real?” to “how can customers access this, and how fast can we scale it?”.
This awareness has driven bold response, focus, and progress from utilities, regulators, and other key decision-makers.
2) New products, including the emergence of residential grid-parallel bidirectional charging
We also saw a meaningful emerging VGI product trend: bidirectional charging systems are increasingly being marketed and deployed for use in grid-parallel configurations, not just for use when islanded from the grid.
These grid-parallel configurations enable:
Customer bill savings (e.g., time-of-use optimization),
Participation in grid programs (e.g., Demand Response or “Virtual Power Plant (VPP)” offerings), and
Real-world “stress-testing” of utility interconnection processes, to ensure grid safety and reliability while informing future interconnection streamlining efforts.
For example, Ford recently launched its Home Power Management solution, which enables customers in select areas to leverage their bidirectional charging system to save money on their electric bill. Volvo and Polestar also launched their grid-parallel bidirectional charging collaboration with dcbel, while Kia and Hyundai launched and later expanded rollout of grid-parallel bidirectional charging from the Kia EV9 to the Kia EV6 and Hyundai Ioniq 9.
3) Interconnection progress: rules are starting to catch up
Interconnection was VGIC's first-ever strategic focus area back in 2020, and it remains our most important initiative to this day. In 2025, we saw significant progress on this front:
Maryland: First comprehensive vehicle-to-grid (V2G) interconnection rules took effect, serving as a model framework that can be replicated in other states.
Michigan: The Commission issued a declaratory ruling clarifying that systems operating in bidirectional charging mode only when islanded from the grid do not need to move through an interconnection process.
California: The major utilities committed to - and the Commission approved - incorporating the alternative V2G AC certification pathway (i.e., the forthcoming UL 1741 CRD for distributed energy resources (DER) Systems) at least as an interim solution. Once UL 1741 SC is published, the state’s V2G AC Interconnection Working Group will re-convene to incorporate V2G AC configurations into Rule 21. Note that in 2020, the Commission clarified that V2G DC systems were already eligible to interconnect under Rule 21.
With additional engagement and developments on deck in Nevada, Texas, New York, and Massachusetts, VGIC is eager to continue its focus on clarifying and streamlining interconnection processes in 2026.
4) New deployment models: making bidirectional charging systems easier to access
In 2025, the industry and funding environment continued its shift from small demos to new, larger “deployment initiatives” that reduce friction for a larger number of early adopters.
In Massachusetts, the MassCEC’s Vehicle-to-Everything (V2X) Demonstration project offers free bidirectional charging systems, including installation costs, to up to 100 residential, commercial, and school bus customers.
In California, Bidirectional Energy and dcbel are offering deeply discounted bidirectional charging systems. This California Energy Commission-funded initiative ties these adoption incentives directly to program participation, encouraging grid-interactive charging and discharging.
Bidirectional Energy is also offsetting upfront bidirectional charging system costs for customers in Connecticut, backed by the state’s Innovative Energy Solutions program.
Specifically in Pacific Gas & Electric’s (PG&E’s) service territory, up to 1,000 customers can access enrollment incentives and other upfront cost support for bidirectional charging systems.
These larger-scale deployment initiatives are already yielding new lessons and insights to support the next stage of scale-up for bidirectional charging systems.
5) Building consistency for managed charging programs: VGIC’s Utility Collaboration Forum published Best Practices for Program and Pilot Development
Although there were many exciting developments in the bidirectional charging space in 2025, VGIC is proud to report on continued advancements for managed charging solutions. In March, VGIC published its Utility Collaboration Forum (UCF) Best Practices document, developed collaboratively with its 40 members as well as BC Hydro, Con Edison, National Grid, PG&E, Puget Sound Energy (PSE), Southern California Edison (SCE), and San Diego Gas and Electric (SDG&E). These Best Practices focus on VGI program and pilot development, offering guidance to utilities and commissioners on how to ensure new pilots and scaled-up programs are:
Simple for customers,
Workable for utilities, and
Durable amid affordability concerns.
This work focused on shortening the learning curve for everyone and, in turn, accelerating the path to widespread VGI.
Two Developments to Come in 2026
1) A strong pipeline of emerging financial opportunities for customers
2026 is poised to be the year that VGI business models crystallize, from residential managed charging platforms and DER-backed fleet charging deployments to bidirectional charging systems and flexible service connection solutions for multi-family EV charging sites.
We’re tracking and proactively developing a growing list of pathways where VGI business models can become reliably financeable and scalable. See just a few of these emerging opportunities in the examples below:
California: Proposed utility rate designs can provide more durable compensation for V2G customers, while utility proposals funded by the Low Carbon Fuel Standard regulation can supercharge distribution-optimized managed charging efforts. Meanwhile, critical utility-led efforts, including the Emergency Load Reduction Program and PG&E’s V2X pilots, provide a bridge while policy stakeholders cement a landscape of customer-centric, cost-effective compensation pathways.
New York: Long-term reforms are on the docket as the state looks to tap into EVs (both unidirectional and bidirectional) as the largest source of load flexibility through 2040.
Maryland: The Commission has ordered utilities to return in early 2026 with much stronger proposals for VPP and V2G programs that scale enrollment and have a far greater impact than those proposed in 2025.
Colorado: The Commission is slated to adopt a customer- and aggregator-friendly VPP framework positioned to attract a significant number of EV customers.
Connecticut: Forthcoming stakeholder work to ensure V2G can be incorporated into the state’s successful energy storage program.
Virginia and Illinois: Growing legislative and regulatory activity to expand VPP programs and EV access to net metering tariffs, respectively, enabling VGI solutions to play a central role in the next generation of demand-side management and DER compensation.
In addition to these many “program dollars” activities, we also expect more industry engagement on behind-the-meter (BTM) time-of-use (TOU) optimization as a near-term customer value proposition, especially as many of these long-term financial opportunities await adoption.
2) Finish line in sight for standards that support V2G AC interconnection
Standards development work isn’t glamorous. Working groups are technically complex and, at times, political. Yet, we are encouraged by increased alignment and activity from key standards development bodies.
In 2026, we expect key progress on the two AC interconnection pathways (UL 1741 SC and the UL 1741 CRD for DER Systems). Once these pathways are published, we can expect attention to shift to incorporating these standards into utility interconnection rules and processes. This will support a repeatable model, ensuring familiarity and comfort for utilities tasked with maintaining safety and grid reliability.
