Hudiksvall Housing Association's Electric Vehicle Initiative Saves Thousands Through V2G Technology

In an innovative pilot project underway since 2021, the Stenberg housing association in Hudiksvall is reaping substantial energy savings through a vehicle-to-grid (V2G) and vehicle-to-home (V2H) initiative, supported by major companies including Volkswagen, Energy Bank, Ambibox, and Vattenfall. All residents in this community utilize electric vehicles (EVs), enabling them to avoid electricity costs while contributing to stabilizing the local energy grid.

Each household reportedly enjoys savings of up to 28,000 SEK annually by supplying support services back to the grid, which translates to a collective reduction of approximately 30% in electricity costs for the association, equating to about 9,000 SEK saved monthly. Klas Boman, a key entrepreneur involved in the project, noted that the simple requirement for residents is to plug in their EVs when they arrive home. The project strategically took root in Sweden due to favorable regulations and an abundance of willing partnerships.

Looking towards the future, Energy Bank intends to roll out an additional 200 pilot projects targeting both individual consumers and businesses, aiming for commercial deployment by late 2025 or early 2026. As the technology matures, Vattenfall projects that the widespread use of V2G systems could lead to significant savings for individual users. With an estimated one million Swedish cars expected to participate by 2030, corresponding energy supplies could match the output of 15 nuclear reactors during peak demand periods.

Christian Jacobsson from Energy Bank assured that advancements in smart charging will enable these electric vehicles to enhance the energy grid rather than disrupt it, reinforcing the potential of such technologies to proactively contribute to Sweden’s energy ecosystem.

This initiative showcases the growing synergy between electric vehicles and renewable energy infrastructure, setting a precedent for community-driven sustainability initiatives.
