The Federal Network Agency is planning to ration the power supply to heat pumps and EV charging stations in order to protect the distribution grids from collapse. Charging times of three hours to charge electric cars will be allowed so that they can cover a distance of 50 kilometers.

Electric cars, heat pumps and private solar systems are booming. This is pushing the power grids in cities and communities to their limits.

An expert quoted by the “FAZ” warns that the local power grids are in danger of becoming the bottleneck for the energy transition. According to estimates, expanding it would cost a three-digit billion amount.

The Federal Network Agency wants to ration electricity for consumers to prevent a collapse in supply.

Electric cars are booming, as are heat pumps and private solar systems on roofs. This should only be the beginning of the energy transition in Germany. But the energy industry is already warning that the local power grids in cities and communities are reaching their performance limits. This has been reported by the “Frankfurter Allgemeine Zeitung” (FAZ). According to the report, the Federal Network Agency is planning to temporarily ration the power supply to heat pumps and charging stations in order to protect the distribution grids from overload.

A year ago, the network agency confirmed a “network development plan” in which up to seven million heat pumps in households are expected for 2035. So far there have been around one million heat pump systems.

Enormous growth is also expected in electric vehicles. For large network operators such as Eon, the current figures are a challenge. “The applications for the connection of new systems are going through the roof, and we assume that the growth rates will continue to grow,” said Eon board member Thomas König. According to the “FAZ”, the electricity supplier registered around 100,000 new charging stations for electric cars in 2021.
Local power grids threatened to become the bottleneck for the energy transition, Krzysztof Rudion, professor at the Institute for Energy Transmission and High Voltage Technology at the TU Stuttgart, told the newspaper. “The expansion of the distribution network simply cannot keep up with the boom in heat pumps, electric cars and solar systems.”

In order to arm the distribution grids, between 100 and 135 billion euros would have to be invested in Germany in the next decade and a half, the FAZ reports, citing a new study by the management consultancy Oliver Wyman.
