Octopus Energy's Vehicle-to-Grid (V2G) Model Faces Challenges in Germany
The British energy company, Octopus Energy, is set to launch a Vehicle-to-Grid (V2G) pilot project in Germany, following its success in the UK. However, the German market presents unique challenges that differ from the UK's more mature market.
V2G, an innovative concept that allows excess renewable electricity to be stored in electric vehicles (EVs) and later fed back into the grid, could become the norm in Germany, as the German Association of the Automotive Industry (VDA) predicts. Yet, the implementation of this technology faces hurdles due to the complex grid connection procedures and high grid fees in Germany.
In contrast, the UK, with over 30% EV penetration, has advanced V2G tariffs and pilot programs. Octopus Energy has launched specific V2G tariffs in the UK, aiming to incentivize EV owners to participate actively in grid services. The UK's market structure, with its somewhat more flexible arrangements, makes V2G implementation easier compared to Germany.
The complex regulatory framework in Germany, with over 100 legislation pieces relevant to the automotive and energy sectors, makes implementation and scaling more difficult. Regulatory complexity and slow grid reform at the EU level block faster adoption of wholesale V2G integration. The need for grid modernization and investment to handle bidirectional energy flows is ongoing but not yet fully realized.
Market price signals in Europe are less volatile compared to places like Texas, reducing strong financial incentives for consumers to participate in V2G at scale. Coordination between multiple stakeholders—vehicle manufacturers, energy providers, grid operators—is intricate under current policy regimes, delaying smooth rollout.
Despite these challenges, Octopus Energy plans to launch pilot projects in Germany. The company will install special wall boxes at customers' homes at no extra cost, allowing them to feed electricity from the grid into their car and vice versa. The pilot project will not be on the same scale as their offering in the UK, but it will still provide valuable insights for all involved.
The leasing model involves storing electricity in the batteries of vehicles and later feeding it back into the grid via a bidirectional wall box. Suitable wall boxes for V2G are still rare, but their availability is expected to increase in the near future. This allows customers to benefit not only from free electricity but also from their vehicle contributing to the stabilization of the power grid.
Despite government subsidies and strong EV sales, Europe’s overall EV market and V2G uptake face slower-than-expected growth due to these structural challenges. Millions of unused car batteries could replace up to 92% of stationary storage systems across Europe, potentially saving 8.4 billion euros in costs per year.
Initial lab tests by RWTH Aachen and electric vehicle service provider The Mobility House have shown that the battery's range is hardly affected by regular charging and discharging. Currently, 22 vehicle models already support bidirectional charging, with more to come.
