Overview：Of all the European countries, Germany's "energy transformation plan" should be the most famous. This is not unreasonable: although Germany has a relatively small share of renewable energy generation compared with Denmark, Portugal and Spain, Germany produces more electricity through renewable energy than any of these countries.
Of all the European countries, Germany's "energy transformation plan" should be the most famous. This is not unreasonable: although Germany has a relatively small share of renewable energy generation compared with Denmark, Portugal and Spain, Germany produces more electricity through renewable energy than any of these countries.
In addition, as the world's fourth largest economy, Germany's economy is larger and more industrialized, so there is a greater demand for reliable energy. In 2014, 24% of Germany's electricity demand was met by wind, biomass and waste power plants.
Most impressive is that Germany has integrated more than 38GW of solar photovoltaic power. The world's largest photovoltaic power generation provided Germany with more than 6% of its electricity supply in 2014. The subsidy policy enacted in 2000 simplifies the process of building solar and other renewable energy projects and sells these interconnected power to local power supply departments at fixed prices. This policy has led to the rapid development of the solar energy industry, set up a model for many other countries, and has been widely adopted.
The strong combination of the German grid and the wider European grid has made the transition to renewable energy much easier in Germany than in Spain or Portugal. Overall, the German government's support for renewable energy is stronger than that of other countries, and it is not susceptible to political turmoil.
However, there are also some problems in the energy transformation policy.
Despite the rapid expansion of the German solar industry, all distributed power generation devices, including solar photovoltaic facilities, will automatically disconnect from the main grid if the system frequency exceeds 50.2 hertz, i.e. when the electricity supply exceeds the demand, under the existing German standards for power interconnection. At noon, when the sun is strongest, solar power sometimes exceeds 40% of Germany's total electricity demand, so this standard may lead to huge photovoltaic capacity offline.
In 2012, Germany began requiring all photovoltaic systems to reset their frequencies to compensate for these shortcomings. This means that at least 315,000 existing devices equipped with smart converters will be revamped to automatically reduce power output when the frequency is too high, and the estimated cost of such revamping is 65 million to 170 million euros.
In addition, Germany must eliminate the constraints of its transmission network. Germany currently plans to have 30 GW of wind power installed in the north by 2020, but new transmission facilities will have to be built to deliver these electricity to densely populated cities in the south.
To make matters worse, when the new coalition government came into power in 2013, its attitude towards renewable energy was even more uncertain than that of the previous one.
In August 2014, a new bill drafted by German Minister of Energy and Economy, Sigmar Gabriel, came into force. Other things aside, the bill excludes large systems from subsidies and imposes surcharges on owners who consume electricity generated by their own photovoltaic systems. This restricts the promotion speed of the photovoltaic industry. The installed capacity of the new photovoltaic industry has decreased from 3.3GW in 2013 to less than 2GW in 2014. This has led to a sharp decline in Germany's transition to renewable energy. So, although Germany's energy transformation has not ended, it has actually slowed down dramatically.
