Battery trader The Mobility House restructures around V2G and Eastern European storage markets

German battery storage optimizer and flexibility trader The Mobility House Energy has appointed Peter Dworak to the newly created role of Chief Executive Officer, while co-founder Marcus Fendt will leave the business after 16 years.

Fendt, who helped build the Munich-based company alongside founder Thomas Raffeiner in 2009 and served as Managing Director and Chief Sales Officer of the energy subsidiary, will remain until the end of March to oversee the handover.

Dworak brings more than 30 years of European energy market experience, including senior roles at Swiss utilities Atel and Alpiq, with a background in cross-border portfolio integration and trading desk expansion. A physicist by training, Dworak had already been working with The Mobility House Energy on a project basis since mid-2026, spearheading its commercial entry into Poland and Romania.

The leadership change accompanies a structural split in how the group handles behind-the-meter and grid-scale flexibility. Going forward, parent company The Mobility House (TMH) will operate as an aggregator bundling flexibility from electric vehicles and buildings via vehicle-to-grid (V2G) and vehicle-to-home (V2H) applications. The Mobility House Energy will act as the market-facing optimization partner, trading that aggregated capacity alongside stationary batteries on European wholesale and balancing markets.

This is another indication that V2G is shifting from pilot projects, such as TMH’s commercial V2G rollout with Renault, towards an actual trading desk asset class.

The Mobility House Energy currently manages and trades an active stationary storage portfolio exceeding 1 GW across European power and ancillary service markets, up significantly since it partnered with GESI in 2024 to commercialize an 8 GW German project pipeline. Alongside geographic expansion into Central and Eastern Europe, Dworak has been tasked with upgrading the company’s proprietary algorithmic trading and optimization software.

Thomas Raffeiner, founder and CEO of The Mobility House AG, said Dworak was selected specifically to scale the European partner business. Raffeiner also credited Fendt with driving the company’s commercial expansion over the past decade and a half, noting his role in opening new business segments and establishing early automotive and utility partnerships.
