The important points of the new renewable energy act (EEG) of Germany are fixed. After notification by the European Commission the new amendment to the EEG is to come into effect in January 2017.

The most important change of the new EEG 2017 is the switch from fixed feed-in tariffs to competitive tenders by the Bundesnetzagentur, the German regulator. Through this change the government aims to introduce a quantity control for the installations of renewable energies. By 2025 renewable energies should have a share of 40 to 45 percent of the total power consumption. For citizen’s energy projects special regulations apply, they do however also have to take part in the tenders.

The yearly quantities of wind power, PV and biomass to be tendered are shown below. It should be noted that the real tender volumes are only published ahead of each tender:

Onshore wind:

  • Tenders for facilities larger than 750 kW
  • 2017 to 2019: Tender volume of 2800 MW (brutto) annually
  • From 2020: Tender volume of 2900 MW (brutto) annually

Offshore wind:

  • From 2021 bis 2025: Tenders of 3.1 GW
  • From 2026: Average tender volume per year 840 MW
  • Target in 2030: 15 GW of installed capacity


  • Tenders for facilities larger than 750 kW
  • Tender volume of 600 MW (brutto) annually
  • Total additions: 2500 MW per year


  • Tenders for facilities larger than than 150 kW
  • 2017 to 2019: Tender volume of 150 MW (brutto) annually
  • From 2020: Tender volume of 200 MW (brutto) annually

The development of installed capacity according to the current version of the EEG 2017 is shown in figure 1. A steady increase in installed capacity can be recognized up until 2040, while the dismantling of old renewable energy plants offsets the installation of new ones afterwards. That implies that net dismantling of renewable energy power plants can occur.

This expansion path is certainly only valid, if no new amendments of the EEG will occur during that time. It is however likely that there will be new amendments changing the renewable energy framework in the future.

In addition, wind power expansion via tenders is limited in grid extension areas, i.e. areas where grid bottlenecks exist. The grid extension areas have yet to be determined and only 58 percent of the average expansion of wind during the years 2013 to 2015 is being tendered there. Simultaneously, in those areas so-called interruptible loads with a capacity of up to 2000 MW can be employed to offset high renewable feed-in.

Regional certificates have been introduced as should enable direct marketing for regionally produced electricity from renewable energy facilities under the EEG 2017 regime.

The energy sector in Germany debates about the positioning of bids in the tenders for onshore wind. It is especially important to determine the position of one’s own bid in the merit-order for the tenders, when compared to the bids of competitors. All participants in the tender therefore have to identify which cost degression for onshore wind can be incorporated into the bids, as the construction of facilities can be delayed up to 30 months after winning in a tender. With the new single-stage reference-yield model it is also very important to conduct an exact assessment for the reference yield of the wind turbines participating in the tenders.

Other important points are the self-consumption and storage. Here it is especially relevant which taxes, fees and levies apply for which use cases. In a similar manner, PV-for-tenants business models attracted attention. In some cases part of the current renewable energy levy can partly be waived. This might make PV-for-tenants a viable business model again and might represent a growing field.
