Solar storage systems in Germany exempted from double grid fees

On Friday (November 10), the German Bundestag passed an amendment to the Energy Industry Act (Energiewirtschaftsgesetz, EnWG) that will make it easier to operate solar energy storage systems. The deadline for exempting storage systems from double grid fees will be extended by up to three years. In contrast, the previous regulation only provided that storage systems commissioned by 4 August 2026 would be exempt for 20 years.
The aim is to ensure that electricity which is fed back into the grid from the storage system and then supplied to the end consumer is not charged twice with grid fees, i.e. once when it is stored and then again after it has been fed back into the grid and supplied to the end consumer.
The German Solar Industry Association (BSW Solar) welcomes the simplifications, but regrets that they have not been made permanent. Instead, according to today's decision by the Bundestag, the Federal Network Agency (Bundesnetzagentur, BNetzA) will decide on future regulation.
