Kia and Hyundai, together with energy company Vattenfall, have launched a large-scale pilot project in the Netherlands in which electric vehicles are used as mobile home batteries, allowing users to supply electricity back to their homes and the grid. This makes the Netherlands a world first, as it is the first country to run this type of consumer trial on this scale.A total of 80 consumers are participating in the pilot. The first phase begins in the second half of 2026 and involves 40 private owners of the electric Kia EV9.
