The WindNODE objective is to integrate large volumes of renewable electricity into the energy system while keeping the power grids stable, says the CEO of the utility, Thomas Bethke, during an on-site visit. The new heat accumulator, with a capacity of about 1,000 cubic metres, should go operational in the early second quarter of 2020. It will be used as a grid buffer and should be complemented with a Power-to-Heat unit in the future. “Excess electricity from renewable sources, for instance large offshore wind turbines, is converted into heat and stored,” Bethke goes on to explain. This way, the electrically heated water, which is ‘parked’ in the heat accumulator, can be successively fed into the district heating system of the city as needed. The storage unit, with a height of about 18 metres and a diameter of some 10 metres, is being built behind the central heat plant, in the direction of Bahndamm.
“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.
