What happens to the electricity grid if more and more electric cars not only demand power but also feed it back (V2G)? <\/strong>This is the main question ElaadNL researchers set out to answer. They focused on charging and discharging at home, where they expect the fastest growth of V2G. The conclusion is promising: if nearly all cars are eventually equipped with V2G capability, and the necessary ICT systems are well in place, electric vehicle batteries could become a major source of flexible capacity. This flexibility would allow cars not just to avoid adding to peak demand but to actively reduce it, helping to ease pressure on the grid.<\/strong><\/p>\n

The report “Bidirectional Charging: Which Way Is It Going?”<\/em><\/a> was published on August 7, 2025, and presented in a webinar<\/a>. In this report, ElaadNL researchers examine the current state of bidirectional charging and its potential to support the electricity grid. Additionally, a “bidirectional charging dashboard<\/a>” has been developed to provide more insight into V2G charging profiles. An interactive map visualizes the impact at the neighborhood level.<\/p>\n

To quantify the potential of bidirectional charging, or vehicle to grid (V2G), the researchers examined passenger cars and vans charged and discharged on household property. According to the study, this form of V2G is expected to see the fastest adoption. An estimated 19% of charging demand for passenger cars will be charged using a home charger, and 9% for vans. Assuming that people using V2G at home want to minimize costs, V2G charging profiles will emerge. In these profiles, vehicles charge when electricity is cheapest, discharge power back to the grid when prices are high, and maximize the use of self-generated solar power. This creates clear differences compared to non-V2G profiles: on average, vehicles supply energy back to the grid during the evening peak, while the charging peak shifts to the quieter nighttime hours, which is generally beneficial for the local power grid. On average, V2G at home provides to 1 to 2 kilowatts of power per household during peak hours (see Figure 1). For an individual household, this can be as much as 11 kilowatts.<\/p>\n

By combining several factors such as expected share of home charging, expected charging profiles, forecast for number of electric vehicles, and 100% adoption of V2G in 2050, the researchers outline the potential impact of home-based bidirectional charging. The researchers estimate that by 2050, bidirectional home charging points could provide up to 4.5 gigawatts (GW) of flexible capacity to the electricity grid. To put this into perspective: the Netherlands\u2019 current daily peak demand is about 22 GW. By 2050, this is projected to increase to 46.9 \u2013 61.7 GW, depending on the scenario (Netbeheer Nederland).<\/p>\n","protected":false},"excerpt":{"rendered":"
