Wind-to-heat storage

Wind-to-heat storage systems use surplus renewable energy to generate and store heat. To do this, electrical current is converted into heat via a heating element and stored in large hot-water tanks.

This principle – also known as ‘power-to-heat’ – makes it possible to use electricity from wind and solar energy when it is not currently needed in the grid. The energy is not lost, but is stored in the form of heat and used later.

In the ENERTRAG Verbundkraftwerk®, wind-heat storage systems help to utilise energy from renewable sources even more efficiently. Surplus electricity from wind energy can be converted directly into heat and made available to local heating networks.

This balances out fluctuations in electricity generation and ensures that renewable energy is utilised in full, rather than having to curtail plant output. At the same time, it creates a climate-friendly local heat supply.

In this way, the Verbundkraftwerk links the electricity and heating sectors into a single energy system – efficient, regional and renewable.
