* Quantity-weighted averages across all tariffs (standard contract with the basic supplier, special contract with the basic supplier, contract with an energy supplier other than the basic supplier) as of April 1, 2020.

EEG = Renewable Energy Act; KWKG = Combined Heat and Power Act.

The statistics show the development of the composition of the electricity price for household customers in Germany in 2020 and 2021. In 2021, the electricity tax for private households in Germany was 2.05 euro cents per kilowatt hour.

• Surcharge for loads that can be switched off – 0.01 cents

* Offshore liability levy until 2018.

The information refers to a 3-person household with an annual consumption of 3,500 kilowatt hours. Some values ​​are rounded. The concession fee refers to the average; it varies depending on the size of the community.

Amount of the EEG surcharge for household electricity customers in Germany from 2003 to 2021 (in euro cents per kilowatt hour)

The values ​​for the years from 2019 were taken from the same publications from the previous year. The values ​​for the years 2010 to 2018 come from the reports of the 4 transmission system operators. The values ​​for the years before 2010 come from the publication “Exemption of energy-intensive industries in Germany from energy taxes” published in 2012.

In 2021, private households in Germany will pay 6.5 cents per kilowatt hour of electricity for the EEG surcharge. The EEG levy serves to promote renewable energies in accordance with the Renewable Energy Sources Act. It is part of the electricity price and represents the difference in costs between the market price for electricity and the subsidy rate for renewable energy sources.

Composition of electricity prices

In 2019, household customers in Germany paid an average of 31.94 cents per kilowatt hour of electricity in the basic supply tariff. The electricity price in Germany is made up of various items. The EEG surcharge, network fees and the “procurement and sales” factor make up the largest share of the total price.

Industrial electricity prices

The price of electricity for industry in Germany has tended to rise since the turn of the last century. However, if the prices are considered without taking into account the imposed electricity tax, a decline in prices can be seen in this country. Just as for private households, the electricity price in industry is mainly made up of the items network fees, procurement and sales as well as the EEG surcharge. In a European comparison, Malta, Ireland and Cyprus are the countries with the highest industrial electricity prices.

South Korea future market for renewable energies – Image: @shutterstock|Anton_Medvedev

When the nuclear disaster occurred in Fukushima, Japan, on March 11, 2011, there was great horror in South Korea, 1000 km away. And the violent earthquake on November 15, 2017, triggered by geothermal drilling in the southeast of the country, where four nuclear reactors are located just a few kilometers from the epicenter, still has an impact today.

“In South Korea, nuclear power has been supported by the government for a good 40 years, primarily because we have no natural resources.” With this statement, Daum Jang from Greenpeace aptly describes South Korea's dilemma. He further mentions in an interview that newspapers that annoy him, such as industry-oriented daily newspapers, use the German energy transition as a negative example and emphasize the costs of German climate policy, but not the benefits. Well, the situation has changed since Fukushima and President Moon Jae-in has confirmed his plans to phase out nuclear power. However, he faces a strong lobby, but the mood of the South Korean population leaves no other choice.

The Austrian Climate Protection Ministry (BMK) also wants to simplify funding for photovoltaic systems on roofs with the future Renewable Energy Expansion Act (EAG). On Thursday, September 10th, Climate Protection Minister Leonore Gewessler presented details of the planned measures: From 2021, as part of the new Renewable Energy Expansion Act (EAG), subsidies for photovoltaics (PV) will also be made much more efficient. The focus is on additional approaches, more transparency and a clearer and more accessible funding system.

PV systems should primarily be installed on buildings or structures (e.g. parking lots, noise barriers, operating facilities). The big advantage lies in the existing infrastructure, for example for network connections. However, many roof surfaces are not yet suitable for PV. In this sense, a corresponding accompanying program is planned to improve the mobilization of roof systems. In addition, a funding program for innovative systems (roof-integrated systems, building-integrated systems, etc.) will be made available from next year.

While power grids with central power generation have dominated so far, the trend is towards decentralized generation systems. This applies to production from renewable sources such as photovoltaic systems, solar thermal power plants, wind turbines and biogas plants. This leads to a much more complex structure, primarily in the area of ​​load control, voltage maintenance in the distribution network and maintaining network stability. In contrast to medium-sized to larger power plants, smaller, decentralized generation systems also feed directly into the lower voltage levels such as the low-voltage network or the medium-voltage network.

An intelligent power grid integrates all actors into an overall system through the interaction of generation, storage, network management and consumption. Power plants (including storage) are already controlled in such a way that the same amount of electrical energy is always produced as is consumed. Intelligent power grids include consumers as well as decentralized small energy suppliers and storage devices in this control, so that, on the one hand, consumption is balanced in time and space (smart power/intelligent power consumption) and, on the other hand, non-disposable generation systems (e.g. wind energy and PV Systems) and consumers (e.g. lighting) can be better integrated.

Due to the larger share of renewable energies, it is becoming more important to align the fluctuations in energy production with the fluctuations in energy consumption. In addition to the possibility of storing electrical energy using energy storage or storage power plants, demand-based electricity generation, e.g. B. through hydroelectric power plants or bioenergy, the expansion of power grids for rapid distribution over a large area, there is also the possibility of adapting power consumption to the power supply.

Photovoltaics: The billion-dollar business with daylight – @shutterstock | 24Novembers

The share of photovoltaics in electricity generation from renewable energy sources is continuously increasing. An important reason is the comparatively low investment costs for the conception and implementation of new systems. It is often possible to attach the modules to existing roofs or buildings, which reduces the space required by the systems to a minimum.

In addition to producers and the environment, hardware producers also benefit from the booming daylight business. There are now over half a dozen companies in the world that each generate sales of over a billion US dollars with solar technology. Above all, the Chinese company Jinko Solar, which recorded revenue of USD 4.3 billion in 2019.

German companies are also involved in the big provider game. Last year, SMA Solar Technology AG from Niestetal in northern Hesse broke the billion dollar sales mark for the first time and thus established itself among the world's leading producers.
