Nuclear power in Germany

The Grafenrheinfeld Nuclear Power Plant in Germany.

Nuclear power in Germany accounted for 23% of national electricity consumption,^[1] before the permanent shutdown of 8 plants in March 2011. German nuclear power began with research reactors in the 1950s and 1960s with the first commercial plant coming online in 1969. It has been high on the political agenda in recent decades, with continuing debates about when the technology should be phased out. The topic received renewed attention at the start of 2007 due to the political impact of the Russia-Belarus energy dispute and in 2011 after the Fukushima I nuclear accidents.^[2]

On 30 May 2011, Germany formally announced plans to abandon nuclear energy completely within 11 years. The plan includes the immediate permanent closure of six nuclear power plants that had been temporarily shut down for testing in March 2011, and two more that have been offline a few years with technical problems. The remaining nine plants will be shut down between now and 2022. The announcement was first made by Norbert Röttgen, head of the Federal Ministry for Environment, Nature Conservation and Nuclear Safety, after late-night talks.^[2][3]

Chancellor Angela Merkel said the phase-out of plants, previously scheduled to go offline as late as 2036, would give Germany a competitive advantage in the renewable energy era, stating, "As the first big industrialized nation, we can achieve such a transformation toward efficient and renewable energies, with all the opportunities that brings for exports, developing new technologies and jobs". Merkel also pointed to Japan's "helplessness" – despite being an industrialized, technologically advanced nation – in the face of its nuclear disaster.^[4] Some German manufacturers and energy companies have criticized the plans, warning that Germany could face blackouts.^[5]

History

Nuclear power plants in Germany

Germany, like most countries in the world, generates the majority of its electricity from traditional fossil fuel sources. Nuclear power was developing as a major source of generation until political pressure stopped its growth in the mid-1980s. Since then no new generating stations have been constructed.

At the time of the Japanese disaster, Germany was getting just under a quarter of its electricity from nuclear power, which is about the same percentage as the United States.^[4]

West Germany

As in many industrialised countries, nuclear power in Germany was first developed in the late 1950s. Only a few experimental reactors went online before 1960, and an experimental nuclear power station in Kahl am Main opened in 1960. All of the German nuclear power plants that opened between 1960 and 1970 had a power output of less than 1,000 MW and have now all closed down. The first commercial nuclear power plant started operating in 1969. Obrigheim, the first grid station, operated until 2005. (Neckarwestheim.)

A closed nuclear fuel cycle was planned, starting with mining operations in the Saarland and the Schwarzwald; uranium ore concentration, fuel rod filling production in Hanau; and reprocessing of the spent fuel in the never-built nuclear fuel reprocessing plant at Wackersdorf. The radioactive waste was intended to be stored in a deep geological repository, as part of the Gorleben long-term storage project.

East Germany

The Rheinsberg Nuclear Power Plant was the first (mostly experimental) nuclear power plant in East Germany. It was of low power and operated from 1966 until 1990. The second to be commissioned, the Greifswald Nuclear Power Plant, was planned to house eight of the Russian 440 MW VVER-440 reactors. The first four went online between 1973 and 1979. The other four were cancelled during different stages of their build-up. In 1990, during the German reunification, all nuclear power plants were closed due to the differences in safety standards. The Stendal Nuclear Power Plant, which was under construction at the time, was cancelled.

Politics

See also: Anti-nuclear movement in Germany

During the chancellorship of Gerhard Schröder, the social democratic-green government had decreed Germany's final retreat from using nuclear power by 2022, but the phase-out plan was initially delayed in late 2010, when during the chancellorship of center-right Angela Merkel the coalition conservative-liberal government decreed a 12-year delay of the schedule.^[8] This delay provoked protests, including a human chain of 50,000 from Stuttgart to the nearby nuclear plant in Neckarwestheim.^[9] Anti-nuclear demonstrations on 12 March attracted 100,000 across Germany.^[10]

On 14 March 2011, in response to the renewed concern about the use of nuclear energy the Fukushima incident raised in the German public and in light of upcoming elections in three German states, Merkel declared a 3-month moratorium on the reactor lifespan extension passed in 2010.^[11] On 15 March, the German government announced that it would temporarily shut down 8 of its 17 reactors, i.e. all reactors that went online before 1981.^[12] Former proponents of nuclear energy such as Angela Merkel, Guido Westerwelle, Stefan Mappus have changed their positions,^[13] yet 71% of the population believe that to be a tactical manoeuvre related to upcoming state elections.^[14] In the largest anti-nuclear demonstration ever held in Germany, some 250,000 people protested on 26 March under the slogan "heed Fukushima – shut off all nuclear plants".^[15]

Decision to abandon nuclear power

On 30 May 2011, the German government announced a plan to shut all nuclear reactors by 2022.^[16] Environment Minister Norbert Röttgen stated of the decision, "It's definite. The latest end for the last three nuclear power plants is 2022. There will be no clause for revision".^[2] Prior to the decision, Germany's renewable energy sector already provided 17% of Germany's electricity and employed about 370,000.^[4] The decision to phase-out nuclear power has been called the swiftest change of political course since unification.^[17] Only a year earlier Angela Merkel's government overturned a decade-old decision to close all nuclear plants by 2022.^[17]

Merkel stated that Germany "[does not] only want to renounce nuclear energy by 2022, we also want to reduce our CO₂ emissions by 40 percent and double our share of renewable energies, from about 17 percent today to then 35 percent". The chancellor, who holds a PhD in chemistry, noted the "helplessness" of Japan to manage the Fukushima Daiichi nuclear disaster. Merkel asserted that Germany's energy policy would be safe, reliable, and independent from imports, with affordable prices for both consumers and industry. Increased investment in natural gas plants would provide a backup to ensure consistency for those times when the solar, wind and hydroelectric sources did not meet demand.^[4]

By turning to the Czech Republic, France and Austria to ensure supplies, Germany is raising the risk of outages as it leads Europe’s economic recovery. The change risks straining utility networks in at least seven countries, Bundesnetzagentur, the nation’s electricity-grid regulator, said in May 2011.
 To make up the shortfall, Germany is moving power south from wind parks in the north, requiring transmission along neighboring grids run by Poland’s PSE-Operator SA and CEPS AS of the Czech Republic because its own system lacks the capacity. That leaves those grids at risk because they were built at least 30 years ago to handle domestic demand two decades before the countries joined the European power-trading system.

Germany will be a net importer of about 4 terawatt hours (TW·h) of power in 2011 after exporting 14 TW·h last year, Deutsche Bank said in a July 5, 2011 report. The German system needs about 10 billion euros ($14.3 billion) of upgrades by 2020 if the country is to stop using neighboring networks, according to the German Energy Agency (DENA), a researcher part-owned by the government. The upper house of parliament approved a bill July 8 to speed up improvements.

Renewable energy to replace nuclear

Main article: Renewable energy in Germany

Since nuclear power generates almost a third of the electricity in Germany, many thought that the country would have to import energy as the nuclear phase-out progressed. However, Germany is still selling more electricity than it buys, due to its renewable energy industry.^[18] Renewable energy supplied a record 20.8% of Germany’s electricity in the first half of 2011, from wind power, solar power, biomass and hydro. Germany installed over 7,400 MW of solar in 2010 and another 7,000 MW will be added in 2011. Solar and wind capacity is expected to grow by 32% from 2012–2013. The surge in renewable energy is credited with driving down the price of electricity in Germany.^[18]

Germany has combined the phase-out with an initiative for renewable energy and wants to increase the efficiency of fossil power plants in an effort to reduce the reliance on coal. According to the former German Minister for the Environment Jürgen Trittin, in 2020, this would cut carbon dioxide emissions by 40 percent compared with 1990 levels. Germany has become one of the leaders in the efforts to fulfill the Kyoto protocol. Critics of the German policy have called it a mistake to abandon nuclear power, claiming the only alternative to nuclear power was coal and abandoning nuclear power was therefore contradictory to the goal of lowering CO₂ emissions.^[19]

As a result of its efforts and subsidies, Germany has developed advanced non-conventional renewable energy for electricity generation, particularly in photovoltaic and wind turbine installations. At the same time, Germany continues to rely heavily on coal power, with usage increasing to offset the phase-out of nuclear energy.^[20]

The German nuclear industry has insisted that its shutdown would cause major damage to the country's industrial base. The cost of replacing Germany's nuclear power generation with renewable energy has been officially estimated by the German Ministry of Economics at about €0.01/kW·h (about €55 billion for the next decade), on top of the €13 billion per year already devoted to subsidizing renewables. However, unofficial estimates of the ministry, and of the Rhenish-Westphalian Institute for Economic Research (RWI), German Energy Agency (DENA), Federation of German Consumer Organizations (VZBV), and the government-owned development bank (KfW), put the cost several times higher, at about €250 billion ($340 B) over the next decade.^[21][22]
