Could deliver 15 times more value than one-way managed EV charging: report

A new study commissioned by General Motors suggests vehicle-to-grid (V2G) integration could deliver five to 15 times more value per electric vehicle in many electricity markets than one-way managed charging (V1G). The nationwide potential value of V2G is estimated at about $7 billion by 2030, according to energy modeling consultancy E3. GM says “bidirectional-capable” EVs—able to both charge from and discharge to the grid—are expected to become more common even as new EV sales decline this year and utilities have limited full-scale V2G adoption. GM previously urged utilities to improve tariffs, program enrollment, and deployment processes to capture more value.
