Unlocking Electric Vehicle Flexibility for Savings and Optimization

In a recent study conducted by Eurelectric and EY, it has been revealed that electric vehicle (EV) owners in Europe have the potential to save between €450 and €2,900 annually by utilizing smart and bidirectional charging. This innovation allows for excess electricity to be stored in EV batteries, which can then be sold back to the grid during peak demand periods. Not only does this benefit individual consumers, but it plays a critical role in balancing the power system, decreasing congestion, and integrating variable renewable energies.

The Challenge

Despite the advantages, consumers currently lack clear economic incentives to provide this service. To unlock this immense potential, it's essential to establish clear pricing signals, improve access to flexibility markets, and ensure interoperable data across the electric mobility ecosystem.

With the integration of more renewable energy sources into the system and the electrification of final consumption sectors, the demand for flexibility in Europe is expected to double within the next five years. The study estimates that by 2030, EV batteries could offer approximately 114 TWh of storage capacity, enough to power 30 million households annually, equaling about 4% of projected annual electricity demand in Europe. However, this potential remains largely untapped.

A Dual Benefit

Kristian Ruby, the Secretary General of Eurelectric, highlighted that driving electric cars can be enjoyable and serve as a source of income for drivers while stabilizing the electric system. However, it's vital for consumers to have market options and clear incentives to act. As adoption enters mainstream consumer territory beyond early adopters, the initial high costs still serve as a significant barrier. In 2024, there was a slight decline in EV sales; however, 2025 has shown signs of recovery. By enabling flexibility, consumers could see significantly lower operational costs, ultimately decreasing the total cost of ownership of an EV below that of conventional vehicles.

Infrastructure Concerns

Infrastructure availability remains another pressing issue. Public charging stations saw a 30% increase in 2024, exceeding 820,000 units; this growth must accelerate to meet the European Commission's target of 3.5 million by 2030. This equates to the installation of around 8,600 charging points weekly. Serge Colle, EY's Global Leader for Energy and Utilities, expressed the necessity for the entire electric mobility ecosystem to facilitate options that help consumers view EVs as more than just transportation. User-friendly smart charging solutions with clear economic benefits are key to driving consumer adoption.

Future Savings for Distribution Operators

From a grid perspective, Distribution System Operators (DSOs) could save an estimated €4 billion annually, as increased flexibility would reduce the need for infrastructure expansion. However, this requires DSOs to access real-time digital monitoring systems and interoperable data at no cost, as outlined in the pending EU vehicle data regulation.

To summarize, the path toward realizing the vast potential of electric vehicles involves collaboration among all stakeholders in the electric mobility ecosystem. Clear economic incentives, increased infrastructure deployment, and accessible data will be crucial in making this vision a reality. By doing so, we can turn potential into energy.
