This ARENA Insights Report delves into the impact of alternative network tariff arrangements on the support of Vehicle-to-Grid (V2G) operations. Specifically, the report focuses on how these arrangements influence outcomes for Electric Vehicle (EV) owners and the overall electricity grid. enX, utilising technoeconomic and Powerflow modelling, has found that V2G has the potential to significantly decrease substation critical peak demand whilst also lowering consumer energy bills.

The report highlights the importance of dynamic tariff structures in optimising benefits for the grid. Dynamic tariff structures are identified as the most grid-beneficial arrangement, contributing to the highest rate of peak demand mitigation. This suggests that flexible and responsive pricing mechanisms play a crucial role in enhancing the effectiveness of V2G operations and their positive impact on the electricity grid.

ARENA - Vehicle to Grid - Network tariffs report - Cover This report was commissioned by the Australian Renewable Energy Agency (ARENA) to explore the role of alternative network tariff arrangements in supporting vehicle-to-grid (V2G) operation, and how they contribute to outcomes for EV owners the electricity grid.

While V2G is largely nascent in the Australian market, it is an opportunity we need to prepare for. enX has previously estimated at the storage capacity in Australia’s EV fleet will exceed all other form of storage in Australia’s national electricity market (NEM) by the mid 2030’s. Unlocking a small proportion of this capacity in the form of V2G could result in substantial
consumer energy savings at a relatively low upfront cost.

While the V2G technology scenario is future-focussed, the pricing arrangements we explore are based on current offerings in the market. We have also sought to accommodate the current regulatory constraints on tariff design.
