Terms briefly explained
The Renewable Energy Sources Act (EEG) is the most important legal foundation for the promotion of renewable energies. It has been a key driver of the change that was later referred to as the energy transition.
Over the years, the law has been repeatedly updated and adapted to the latest developments. However, the basic principle has always remained the same and is based on the promotion of renewable energies - particularly wind and solar - in the form of the EEG surcharge. This is also known as EEG remuneration.
Which energy sources does the EEG subsidise?
The EEG subsidises electricity generation from the following renewable energy sources (Section 3 No. 3 EEG):
How funding works with the EEG feed-in tariff
A levy was introduced in 2020 to finance the expansion of renewable energies. This obliges grid operators to prioritise the connection of renewable energy systems to their grid and to purchase and forward the electricity generated.
In detail, the mechanism works as follows:
The current version of the EEG dates from 2023. The aim of the EEG 2023 is to transform the electricity supply into a sustainable and greenhouse gas-neutral system based entirely on renewable energies. The Act is the biggest amendment to energy policy in recent decades.
The overarching goals of the EEG 2023
Why was the EEG levy abolished?
Electricity customers have no longer had to pay the EEG surcharge since 1 July 2022. This decision was part of the German government's relief package for citizens. The levy was replaced by financing from the federal budget, more precisely from the special assets of the Climate and Transformation Fund (KTF). This became questionable in autumn 2023 when the financing of the KTF was stopped by the Constitutional Court. However, when the 2024 federal budget was adopted on 2 February 2024, it was decided that the key relief for citizens - such as the abolition of the EEG levy - would be retained. This will be made possible by redeployment, savings elsewhere and the use of other financing channels.
The measures of the EEG 2023
In view of the 1.5-degree target and the recognised need to reduce CO2 emissions across all sectors, the EEG is generally viewed positively. It is no coincidence that around 65 countries worldwide have adopted at least some of its principles.
In particular, the priority given to renewable energies over building law, monument protection or species protection exemptions is seen as positive for the progress of the energy transition. The accelerated approval procedures from the EEG 2023 are also already making themselves felt.
The quota model and the tendering model are often discussed as competing systems. In the quota model, the state sets a quota of renewable energy that must be produced by energy suppliers. In the tendering model, the required amount of green electricity is put out to tender. The winning bidder receives a limited purchase guarantee for the generation. The advantages of quota and tendering models are politically and scientifically controversial.
It is debatable whether the expansion targets are sufficient for the energy supply of the future. In addition, the infrastructure - i.e. transport capacities, storage options and opportunities through flexibilisation - must be adapted in good time to the conditions brought about by volatile generation from renewable energy sources such as wind and solar. This applies above all in connection with the assumption that electricity demand is likely to rise sharply due to the increase in electromobility and the increased use of heat pumps for heating. In this context, there are repeated discussions about what reserve capacities are needed after the nuclear phase-out and the coal phase-out and how these should be fuelled.
Among other things, improvements are expected in the regulations on land use, further clarification of planning and authorisation law and a nationwide standardisation of species protection.
According to Agora Energiewende, there was a record 14.4 gigawatts of solar installations in 2023, which is well above the targets for 2030. In contrast, there was only a slight increase in wind power installations of 2.9 gigawatts. In order to achieve the statutory expansion targets for 2030, the annual expansion of wind power plants must increase to an average of 7.7 gigawatts from 2024.
In addition to energy generation, the opposite side - private, commercial and industrial energy consumers - must also be considered. Government support is needed here for climate-neutral heating systems, the transformation of industry and the electricity, heating and hydrogen grids of the future.
At the beginning of March 2024, the Federal Ministry for Economic Affairs and Climate Protection presented the introduction of climate protection contracts. This new global funding instrument is based on auctions that companies can use to subsidise their transition to climate neutrality. At the time of writing, it remains to be seen how this instrument will prove its worth.
