Capacity Reserve

The German Energy Industry Act ("Energie­wirtschafts­gesetz") in conjunction with the German regulation for capacity reserve ("Kapazitäts­reserve­verordnung") provides regulation regarding the provision of a capacity reserve in the amount of 2 GW.


In the event of threats to or disruptions of the security or reliability of the power supply system caused by supply/demand imbalances on the German electricity market, the capacity reserve shall be used to compensate for these shortfalls. The capacity can be provided by generating plants, storage facilities and variable load. 

The capacity reserve is formed via a public tender held by the German transmission system operators. Further information regarding the capacity reserve can be found on the common platform by the German TSOs
