As the UK shifts towards electric vehicles (EVs) to reduce carbon emissions, some fear the increased electricity demand could lead to blackouts. Skeptics warn that relying on intermittent renewable energy sources like wind and solar may not suffice during peak times, potentially overwhelming the grid.
However, industry experts argue that these fears are misplaced and that EVs offer a chance to create a smarter, more resilient energy system. The transition will indeed require more electricity, but smart technology can shift demand away from peak times. For example, home charger company myenergi suggests that balancing services could offer the grid over 1GW of demand shift flexibility, surpassing most UK fossil fuel generators.
Octopus Energy, the UK’s largest energy supplier, demonstrates the effectiveness of smart chargers with its Go electric tariff. By managing the charging of 150,000 EV batteries during off-peak hours, it saves customers an average of £600 annually. This smart charging system helps balance the grid, reducing pressure during peak demand times.
Chris Pateman-Jones, CEO of Connected Kerb, believes EVs can act as a “massive sponge,” absorbing excess renewable power during low-demand periods. Data from Connected Kerb shows most cars complete charging by midnight, allowing flexibility in energy usage.
Vehicle-to-grid technology presents another promising solution. By using car batteries as portable power packs, EVs could feed energy back into the grid during high-demand periods. Though widespread implementation of bidirectional charging faces challenges, several carmakers are beginning to incorporate this technology.
Despite uncertainties in business models, Fiona Howarth, CEO of Octopus Electric Vehicles, remains optimistic. She envisions a future where 10 million EVs could potentially power the entire UK during peak times. Electric cars, she argues, are “batteries on wheels” that could help keep the lights on.
As the UK navigates this energy transition, the integration of smart technology and innovative solutions could turn potential challenges into opportunities, ensuring a stable and green energy future.
