A Heart for the Power Grid - How Heat Pumps Provide Balance in the Energy System

The smarter E Podcast Episode 119 | December 2022 | Language: German

The European Union wants to decarbonize the heating sector with heat pumps. To this end, sales figures are to be doubled in the next five years, which corresponds to a total of 10 million heat pumps. Due to the increasing demand for electricity, the load on the power grids is growing, but at the same time heat pumps can contribute to their balance through their flexibility. According to a recent study by the European smartEn association, an additional 510 TWh of electricity will be needed for heating in 2030, but at the same time electric heating in private households also represents the greatest potential for providing flexibility on the consumption side. Heat pump manufacturer Viessmann is working with transmission system operators and other partners to harness the flexibility potential of residential heat pumps. We asked Egbert Tippelt from Viessmann how this works and what obstacles still need to be overcome.
