European cities could cut EV grid bill by 40% with smart charging, study says

What happened

A Siemens study released Tuesday proposes that European cities need almost €25 billion, or $27.94 billion, of charging infrastructure investment by 2030. It says smart charging could cut that electricity distribution grid bill by 40%, saving €10.6 billion, and a European Commission proposal on off-peak prices could help.

Proposed

Global impact / market context

A smaller grid bill lowers the cost of preparing cities for more electric cars, which frees cash for other spending. Utilities and charging firms could face lower capital spending needs, while drivers benefit if off-peak power prices are predictable and cheap.

Analyst inference

The study, backed by charging and auto industry groups, arrives as EU officials consider a proposal on predictable off-peak electricity prices. Grid investment needs concentrate in Germany, Norway, Belgium and the Netherlands, while eastern Europe shows the fastest expected electric car growth from a low base.

Analyst inference

What to watch

1. Watch whether the European Commission's proposal for predictable, cheaper off-peak electricity prices across the bloc advances, since the study says it could help consumers shift charging times. Confirmed
2. Watch whether cities adopt smart meters and time-of-use tariffs that push charging to low-demand hours, because the study says this could cut the €24.7 billion grid investment bill by €10.6 billion. Proposed
3. Watch Germany, Norway, Belgium and the Netherlands for low-voltage grid spending, and eastern Europe for faster electric car growth, since these are where the study sees the biggest needs. Analyst inference
