The Vehicle to Grid (V2G) concept is no longer just a theoretical solution for grid resilience. In 2025, Maryland has positioned itself as a frontrunner in the transition to smart, distributed energy systems. With new rules adopted in 2024, the state offers a working model of how policy, technology, and market dynamics can align to mainstream bidirectional EV charging.

What Makes Maryland’s Policy a Turning Point for V2G?
Maryland's recently approved V2G interconnection rules represent a structural shift in how electric vehicles are treated within the grid. For the first time, EVs are legally recognized as distributed energy resources. This classification allows EVs to participate in ancillary grid services, energy arbitrage, and demand response programs.
The updated COMAR regulations ensure:
- Consistent and transparent approval procedures for V2G charging stations
- Interoperability across vehicle brands and charging hardware
- Alignment with national safety and performance benchmarks
This eliminates prior uncertainties around approval delays and technical requirements, creating a replicable model for other states.
How Will This Impact V2G Commercialization and Grid Integration?
Commercializing V2G relies on both regulatory alignment and utility cooperation. By clarifying technical and procedural expectations, Maryland paves the way for scalable deployment of V2G systems across residential, commercial, and fleet segments.
Utility benefits include:
- Greater access to flexible load and energy storage
- Cost savings through reduced grid congestion and infrastructure deferral
- Real-time energy balancing through aggregated EV fleets
With policy now enabling the technical integration, commercialization is expected to accelerate across stakeholder groups.
What Are the Implications for the EV Charging Ecosystem?
The EV charging sector will be central to implementing V2G solutions. The new rules encourage innovation in:
- Bidirectional EVSE designs
- Communication protocols that support grid signals
- Load management algorithms for real-time response
Manufacturers and energy service companies now have a clear mandate to develop compliant, scalable infrastructure that can capitalize on emerging V2G incentives.
Could Maryland's Model Be Adopted Nationally?
Given its comprehensive nature and stakeholder-friendly approach, Maryland’s framework could serve as a template for other states. The clarity of definitions, technical guidance, and alignment with IEEE/UL standards makes it both rigorous and adaptable.
States that are revisiting interconnection guidelines may find Maryland’s model effective for:
- Streamlining application processes
- Encouraging private sector investment in V2G technology
- Reducing the operational risk for utilities and service providers
If replicated, this could standardize V2G adoption at the national level, enabling a more responsive, sustainable energy grid.
Summary of Strategic Impact
- Maryland legally integrates EVs into the grid as energy assets
- Bidirectional EVSEs receive streamlined regulatory support
- The move can influence national V2G policy and infrastructure investment
Bullet Recap:
- Maryland sets regulatory precedent for bidirectional charging
- Grid operators can now leverage EVs for real-time support
- Charging providers must scale interoperable solutions
- National replication could accelerate V2G adoption
Next Steps:
- Scale bidirectional charger installations in line with Maryland’s safety and compliance rules.
- Forge state-utility collaborations to replicate this framework across other jurisdictions.
- Refine fleet strategies to integrate V2G into logistics, public transit, and commercial delivery.
- Invest in workforce training for EV technicians specializing in grid-interactive hardware.
- Track policy developments to align business models with evolving regulatory landscapes.
