Despite widespread rumors in North America that Germany was abandoning its system of Advanced Renewable Tariffs, the country’s upper chamber of parliament, the Bundesrat, approved the latest revision of its pioneering Renewable Energy Sources Act [PDF] on July 8, 2011.

The action follows approval by Germany’s House of Commons, the Bundestag, on June 30, 2011.

The new version of the law first introduced in Germany in 2000 will go into effect Jan. 1, 2012.

Approval of the latest revisions of the Renewable Energy Sources Act, the Erneuerbare-Energien-Gesetz (EEG) in German, is significant because it follows the nuclear accident at Fukishima, Japan and the debate in Germany about the future of nuclear power.

The 30-year long debate on nuclear in Germany was settled earlier this summer when parliament decisively voted to quit nuclear power by 2022.

Germany is currently ruled by a coalition of the Conservative (CDU/CSU), and the neoliberal (FDP) parties.

Thus, the vote on revisions to the Renewable Energy Sources Act for 2012 follows the decision to quit nuclear power and further expand the role of renewable energy in the electricity sector.

The revisions for 2012 were part of regularly scheduled periodic revisions. Previous revisions occurred in 2004 and 2009.

The 2012 EEG sets a minimum requirement of not less than 35 percent of renewable energy in electricity supply by 2020, not less than 50 percent by 2030 and not less than 65 percent by 2040 and not less than 80 percent by 2050.

However, the law actually sets a target of between 35 and 40 percent of supply within the next decade. This conforms to a decision made by the Ministry of Environment in 2010. See “Germany Ups Renewable Target — Again.”

Rather than reducing its commitment to expanding renewable energy, Germany has codified a more aggressive target than in the previous law.

Final interpretation of the complex 204-page law will be issued by the Ministry of the Environment, the BMU, later this summer.

Some key provisions of the 2012 EEG include

  • Raising biomass tariffs nearly 30 percent from €0.11/kWh ($0.16/kWh) to €0.14/kWh ($0.20/kWh) for plants less than 150 kW in size.
  • Increasing geothermal tariffs more than 50 percent from €0.16/kWh ($0.22/kWh) for small projects to €0.25/kWh ($0.36/kWh) for all projects.
  • Increasing offshore wind tariffs 15 percent from €0.13/kWh ($0.19/kWh) to €0.15/kWh ($0.21/kWh).
  • Increasing the “starter” bonus for offshore wind nearly 25 percent from €0.15/kWh ($0.21/kWh) to €0.19/kWh ($0.27/kWh).
  • Maintaining the 2011 degression for solar photovoltaics (solar PV) into 2012.
  • Maintaining the tariffs for wind energy on land, including the repowering bonus.

Significantly, parliament again stated its support for the rapid development of solar PV in Germany. The 2012 EEG continued the current policy of regulating solar PV development within a “growth corridor” of 3,500 MW per year.

If Germany maintains growth of solar PV of 3,500 MW per year it will remain the world’s largest solar market for the foreseeable future. Both the government and the industry expect solar PV capacity to exceed 50,000 MW by 2020.

Solar PV growth will be regulated by adjustments in the annual degression rate of 9 percent. If the growth exceeds the target, the degression is increased. If growth is less than the target, the degression is decreased.

In addition, the 2012 EEG continues the German reference yield system for wind energy both on shore and off shore. The system is designed to ensure that not only wind energy at windy sites can be developed but also wind energy at less windy sites as well. The system has proven successful. Today, nearly 60 percent of all wind energy in Germany is developed in the less windy interior of the country, taking development pressure off the windy North Sea cost.
