EVs will not upset electricity grids: French operator RTE says

Electricity grids will not falter when millions of electric vehicles (EVs) will be plugged in during peak hours across France in the future, the leading electricity system operator has assured. France is still far behind compared to other European countries in adoption of electric vehicles.

Amid the ongoing shift from conventional internal combustion engines (ICEs) to EVs, many critics have warned that electricity grids will falter, causing widespread power outages, as the system will not be able to handle stress when millions of people will be charging their electric cars at the same time.   

However, France’s electricity system operator Réseau de Transport d'Electricité (RTE) tried to tackle this claim and explain why EVs will not be an impending threat to conventional electricity systems like hydroelectric grids, even when a large number of EVs will be charged at the same time across the country. 

The French electricity operator conducted a study to find how much burden its electricity system will have to bear due to EV charging in 2035, when almost all passenger vehicles will be fully electric. After analyzing the data, the operator reached the conclusion that EV charging, even during peak hours, will represent just 10 per cent of the country’s electricity consumption in 2035. It worth-mentioning here that France is planning to eliminate conventional petrol/diesel-powered vehicles from the public road by 2040. Utility companies in the UK are also considering adding charging network.

According to RTE, the estimated 10 per cent consumption of electricity by EVs by the mid of next decade will be very manageable. It will be less of an impact than the change in France’s energy consumption between 2000 and 2010. At present, the Western European country has 500,000 EVs on public road, but RTE claims that it will be able to accommodate up to 15 million EVs in 2035 without any big concern. 

Among electric vehicle manufacturers, Tesla Motors has been setting up a wide and effective network of charging stations. Other automobile manufacturers have also planned to setup their own charging networks but many companies also provide options for people to have their home charger. 

One of the proposed strategies to decrease the load on the power grids is the vehicle-to-grid (VTG) system, which will allow stationary EVs with surplus power to supply electricity back to the grids to be used by others. Thus, millions of vehicles will be able to replenish the grids in hours of need or an emergency, such as floods. In a similar way, the surplus energy stored in a bike or car’s battery could supply power to a home, or feed into the entire grid system when the demand is very high. RTE also pointed out that the electricity grid systems could accelerate charging during the off-peak hours of the day or when solar energy is in abundance.
