Due to the energy transition there is an increase in the generation of renewable energy. Such as solar parks, solar panels and wind turbines. At times, when the wind is blowing hard and/or the sun is shining fully, the energy grid in parts of the country cannot handle the power. As a result, it is not possible to use all generated energy. And so, windmills must be stopped and solar panels switched off.
To prevent curtailment of renewable energy, an empty battery is the solution. As soon as supply exceeds the demand, the battery stores the amount of excess energy to release this later.
- Prevents curtailment
- Stores excess energy
- Releases energy later
