Unlocking the Power of Electric Vehicles: Savings and Grid Optimization

Eurelectric's recent study highlights how electric vehicle (EV) owners in Europe can save between €450 and €2,900 each year by utilizing smart and bidirectional charging options. This innovative approach allows EV batteries to store excess electricity and trade it back to the power grid during peak demand hours. The result? Not only are drivers benefiting financially, but the electrical grid is also stabilized, reducing congestion and facilitating the integration of renewable energy sources.

However, the research reveals a significant barrier; consumers currently lack adequate economic incentives to engage in such practices. To truly harness the potential of EV technology, clear pricing signals and greater access to flexibility markets are vital. Furthermore, interoperability across the e-mobility ecosystem plays a pivotal role in ensuring that both consumers and utilities can reap the benefits of advanced charging technologies.

As Europe advances towards a greener energy future, the demand for grid flexibility is projected to double within five years. This surge will coincide with increasing dependencies on renewable energy sources and the electrification of various end-use sectors. With estimates suggesting that EV batteries could provide approximately 114 TWh of battery capacity by 2030, it's clear that EVs could potentially power 30 million homes annually, accounting for about 4% of Europe’s projected power demand.

Yet, this vast potential remains largely underutilized. Eurelectric's Secretary General, Kristian Ruby, emphasizes the financial advantages for drivers, stating, “Our study shows EVs can help drivers make money while stabilising the power system, but customers need choice in the market and clear incentives to act.” The transition from early adopters to mainstream acceptance of EVs is crucial, especially as high initial purchase costs continue to deter consumers. Although there was a slight decline in EV sales in 2024, 2025 has witnessed a resurgence with the growing awareness of the benefits of EV flexibility.

This flexibility not only translates to savings for consumers but could also play a significant role in lowering operating costs, adjusting the overall cost of EV ownership to be competitive against traditional vehicles.

Another critical issue facing the EV market is the availability of charging infrastructure. In 2024, the number of public charging stations grew by 30%, surpassing 820,000 units. However, to meet the European Commission's goal of 3.5 million chargers by 2030, the rate of installation must accelerate significantly, requiring about 8,600 chargers to be built each week.

Serge Colle, EY's Global Power and Utilities Sector Leader, asserts, “For consumers to play an active role in flexibility, the entire e-mobility ecosystem must help them consider EVs as something more than simply a means of getting from A to B. Easy-to-use smart-charging propositions with clear cost benefits are critical.”

On the grid management front, Distribution System Operators (DSOs) could save roughly €4 billion annually through improved flexibility, which may help reduce the need for extensive infrastructure expansion. However, successful implementation hinges on the capacity for real-time digital oversight and access to interoperable data at no additional cost.

In summary, there's a unique opportunity to transform potential into reality by optimizing the balance between consumer savings and grid reliability. The adoption of smart and bidirectional charging practices is an essential step toward achieving a sustainable and economically viable future for electric vehicles. As the EV market evolves, focusing on consumer appreciation, infrastructure growth, and operational flexibility will be key to maximizing benefits for all stakeholders involved.
