Grid buffer store in Hennigsdorf

On the premises of the Zentrum boiler house, the construction of the grid buffer store of Stadtwerke Hennigsdorf GmbH is underway. It is a model solution for the smart use of surplus electricity from renewable energy sources.

The new heat accumulator, measuring 18 metres in height and ten metres in diameter, is fit to contain 1,000 cubic metres of water and should be ready to operate at the start of the second quarter of 2020. In the future, the storage unit will be expanded with a Power-to-Heat installation, so that surplus electrical energy from renewable sources can be converted into heat and stored. If needed, hot water can then be fed into the city’s district heating system.

‘The construction of the grid buffer storage unit on the site is a model solution that is significant for all of Germany,’ states Thomas Günther, the mayor of Hennigsdorf. As such, the city is distinguishing itself as a committed trendsetter for the energy transition across state borders.’
