Germany’s EEG levy on electricity prices to support the expansion of renewables, is likely to decrease to about €0.0674 per kilowatt hour (kWh) next year from €0.0688/kWh this year, according to Berlin think-tank Agora Energiewende.
A predicted rise in wholesale power prices is one reason for the expected lower support payments for renewable energy, the think-tank said.
The surcharge aims to bridge the gap between the wholesale power price and the guaranteed feed-in tariff, it added.
The current €3bn surplus in Germany’s “green energy account” could also be used to lower the levy.
The think-tank said that the introduction of support payments in 2019 for new offshore wind farms would increase the surcharge to more than €0.075/kWh, with the levy expected peak between 2021 and 2023.
