From the outside you cannot see what is happening inside. The concrete, with street art brightened up front, parallel to the Leidsevaart, has no windows. A company name is also not on the facade. Only the continuous, low-frequency hum gives a hint as to what the building is for. But since a few weeks the hum has also disappeared.

Since the end of September, there has been no buzz around Boterplein in the city center of Haarlem. At that time, the large-scale work to renew the electricity grid around the city center was completed. “That was earlier than planned,” says Jessica ter Maat, area manager of grid operator Liander. The work was actually expected to last until November.

Technicians who know the city center well

“It doesn’t happen often that we complete such a large project in such a short time,” says Ter Maat. “The challenge was mainly due to the fact that there is little space in the city center. Then you cannot simply connect a generator everywhere to maintain the power supply. Thanks to technicians who know the city center well and good cooperation with the municipality, the operation went smoothly.”
