- E3 found V2G could deliver 5 to 15 times more value per EV than one-way managed charging (V1G) in many electricity markets, according to its study commissioned by GM.
- Nationwide V2G potential value could reach approximately $7 billion by 2030, E3 estimated in its energy modeling analysis.
- GM released an open letter last month urging utilities to modernize tariffs and rate structures, sharpen V2G enrollment incentives, and streamline procurement and permitting of bidirectional chargers.
- Regulatory and program design barriers—including pilot rules and retail export structures—limit how much V2G value utilities and ratepayers can capture, E3 found.
- GM has 250,000 bidirectional-capable vehicles on the road already and committed to the technology for all planned EVs going forward; other bidirectional-capable models include the Kia EV9, Hyundai Ioniq 5, and redesigned Nissan Leaf.
- PG&E's northern California grid is a focal deployment: GM aims to put about 52,000 vehicles to work there by 2030—roughly 40% of its fleet in that utility's territory.
- Per-vehicle V2G value ranges from $2,200–$2,750 in constrained regions like ERCOT and MISO territories, $1,700–$2,200 in the WECC's Pacific Northwest and Rocky Mountain zones, and about $700 in southeastern vertically-integrated markets—still higher than V1G's top regions.
Why it matters: GM is staking a commercial bet on V2G while pressing utilities to clear the regulatory barriers currently throttling value capture. Even the lowest-return V2G region—the Southeast at ~$700 per vehicle annually—outpaces V1G's best markets, tilting the economics toward bidirectional hardware and validating GM's 250,000-vehicle existing fleet plus its 52,000-vehicle PG&E deployment target by 2030.
