Balancing power grid

Enexis also reduces power of charging stations to reduce grid congestion

Since this week, in the service area of grid operator Enexis, 2,200 public charging posts for electric cars are switched back during peak hours on the grid. During these hours, the poles deliver less power to prevent overloading the electricity grid. This concerns charging points spread over several regions in the Netherlands.

Grid operator Enexis operates in the provinces of North Brabant, Limburg, Drenthe, Overijssel and Groningen. The company supplies power to some 15,000 public charging points for electric cars. The number of charging points managed by Enexis is expected to double in the coming years.

2,200 of the charging posts in Enexis’ service area will be automatically ‘dimmed’ during peak hours on the grid from this week. That means they provide less power, and EVs connected to them are less likely to charge. Peak hours are from 4pm to 9pm and from 7am to 10am. Only in areas where power demand is ‘critical’ will the power of charging poles be limited. These are 22 different areas spread across the said service area. Earlier this week, grid operator Stedin also announced that this winter in the province of Utrecht, public charging stations will charge more slowly during power peaks than during off-peak hours.

Whereas initially the restriction of power supply will take place at fixed times (during peak hours), from winter 2026-2027 it will have to be ‘flexible’. That is, charging stations can automatically start supplying less power at times when the grid demands it, and also supply more power again as soon as it is possible again.

Balancing power grid

Enexis calls charging stations ideal for balancing the grid, because cars are often connected for longer than necessary. In many cases, charging can be fine postponed or delayed, so charging stations are power consumers that you can influence well if necessary. The grid operator says charging station users will notice little to no impact from this measure. The company also says that at a large proportion of charging posts, the dimming function can be switched off in urgent cases.
