EVs can function as efficient energy storage systems

The concept of time-of-day (ToD) tariffs offers a game-changing solution. If ToD tariffs are implemented, EVs could act as storage during periods of renewable energy surplus.

Energy storage systems and renewable integration have become the focal points in the modern energy discourse. While these topics are widely discussed, a critical analysis reveals a glaring gap in the approach regulators and system managers take. The current emphasis is predominantly on generation-side management, with measures such as round-the-clock supply, firm dispatchable renewable energy (FDRE), and storage-inbuilt solutions being designed to make renewable energy more reliable. However, this approach largely neglects demand-side management, an area ripe with opportunities for innovation and efficiency.

One of the most promising yet underexplored avenues for addressing renewable integration challenges is effectively using electric vehicles (EVs). The energy sector can achieve remarkable advancements by leveraging EVs as decentralised energy storage units. Currently, the dominant strategy is to make generation follow the load curve, but little attention is paid to managing it. This creates inefficiencies and limits the potential for optimal utilisation of renewable resources.
