Electricity sector in Germany

(Redirected from Electricity in Germany)

Germany's electrical grid is part of the Synchronous grid of Continental Europe. In 2020, due to COVID-19 conditions and strong winds, Germany produced 484 TW⋅h of electricity of which over 50% was from renewable energy sources, 24% from coal, and 12% from natural gas, this amounting to 36% from fossil fuel .[4] This is the first year renewables represented more than 50% of the total electricity production and a major change from 2018, when a full 38% was from coal, only 40% was from renewable energy sources, and 8% was from natural gas.[5]

Gross generation of electricity by source in Germany 1990–2022 showing that the growth of renewables already replaces the soon-to-be-phased-out nuclear (purple), and remaining nuclear partially replacing fossils (gas, hardcoal, lignite)

In 2023, 55% of energy produced was from renewable energy source; a 6.6 percentage points increase from 2022.[6] Within the 55%, 31.1% was attributed to wind, 12.1% to solar, 8.4% to biomass and the remaining 3.4% from hydropower and other renewable.[6]

Germany has consistently produced the most carbon dioxide emissions in the European Union since the turn of the century, a large proportion of this coming from coal and lignite burning power stations, 7 of which are included in Europe's top 10 most CO2 polluting list of 2021.

In 2022, Germany produced nearly 635 million metric tons of carbon dioxide emissions. This was more than the combined emissions produced by the next largest emitters in the EU – Italy and Poland. These three countries accounted for roughly 46 percent of total EU carbon dioxide emissions in 2022.

Germany's installed capacity for electric generation increased from 121 gigawatts (GW) in 2000 to 218 GW in 2019, an 80% increase, while electricity generation increased only 5% in the same period.[7]

Even though renewables production increased significantly between 1991 and 2017, fossil power production remained at more or less constant levels. In the same period, nuclear power production decreased due to the phase-out plan, and much of the increase in renewables filled the gap left behind by closing nuclear power plants. However 2019 and 2020 saw significant reductions in electricity generation from fossil fuel, from 252 TW⋅h in 2018 to 181 TW⋅h in 2020. The German government decided to phase-out nuclear power by end of 2022, however this has been delayed until April 2023 due to supply disruption caused by the Russian invasion of Ukraine,[8] meaning that future growth in renewables will be needed to fill the gap again. Germany also plans to phase out coal by 2038 or earlier.[9]

Electricity prices

edit

German electricity prices in 2020 were 31.47 euro cents per kW⋅h for residential customers (an increase of 126% since 2000),[10] and 17.8 euro cents per kW⋅h for non-residential customers (21.8 with taxes).[11][12][13]

 
Components of the German Electricity Price for Households Source

German households and small businesses pay the highest electricity price in Europe for many years in a row now. More than half of the power price consists of components determined by the state (53%). These taxes, levies and surcharges have tripled since 2000 [from 5.19 to 16.49 Euro Cents]. These include levies for financing investment in renewable energy (22.1%) and for other kinds of taxes (e.g. GST 19%). Grid charges account for almost 25%, and only the remaining 22% are used to actually generate the electricity.

International electricity trade

edit

Germany exported 70,237 GWh of electricity and imported 51,336 GWh in 2021.[14] Germany is the second largest exporter of electricity after France, representing about 10% of electricity exports worldwide. [15][16] Germany has grid interconnections with neighboring countries representing 10% of domestic capacity.[17]: 5 

Electricity per person and by power source

edit

Germany produced power per person in 2008 equal to the EU-15 average (EU-15: 7,409 kWh/person) and 77% of the OECD average (8,991 kW⋅h/person).[18]

On 8 May 2016 renewables supplied 87.6% of Germany's national electricity consumption, albeit under extremely favourable weather conditions.[19]: 11

Germany electricity production by source
 
German electricity generation by source, 2000–2017

According to the IEA the gross production of electricity was 631 TW⋅h in 2008 which gave the seventh position among the world top producers in 2010. The top seven countries produced 59% of electricity in 2008. The top producers were the United States (21.5%), China (17.1%), Japan (5.3%), Russia (5.1%), India (4.1%), Canada (3.2%) and Germany (3.1%).[23]

In 2020, Germany generated electricity from the following sources: 27% wind, 24% coal, 12% nuclear, 12% natural gas, 10% solar, 9.3% biomass, 3.7% hydroelectricity.[4]

Coal

edit
See also: Fossil-fuel phase-out and List of power stations in Germany

In 2008, power from coal supplied 291 TW⋅h or 46% of Germany's overall production of 631 TW⋅h, but this dropped to 118 TW⋅h (24%) in 2020.[4] In 2010 Germany was still one of the world's largest consumers of coal at 4th place behind China (2,733 TW⋅h), USA (2,133 TW⋅h) and India (569 TW⋅h).[23] By 2019 it had fallen to 8th, behind smaller countries such as South Korea and South Africa.[24]

Germany has shut all hardcoal mines by the end of 2018, but still has large open pit mines for lignite in the Western and Eastern parts of the country.

In January 2019 the German Commission on Growth, Structural Change and Employment initiates Germany's plans to entirely phase out and shut down the 84 remaining coal-fired plants on its territory by 2038.[9]

Nuclear power

edit
Main article: Nuclear power in Germany

Germany has defined a firm active phase-out policy of nuclear power. Eight nuclear power plants were permanently shut down after the Fukushima accident. All nuclear power plants are to be phased out by the end of 2022.

Siemens is the only significant nuclear constructor in Germany and the nuclear share was 3% of their business in 2000.[25]

The installed nuclear power capacity in Germany was 20 GW in 2008 and 21 GW in 2004. The production of nuclear power was 148 TW⋅h in 2008 (sixth top by 5.4% of world total) and 167 TW⋅h in 2004 (fourth top by 6.1% of world total).[23][26]

In 2009, nuclear power production saw a 19% reduction compared to 2004, and its share had declined smoothly over time from 27% to 23%. The share of renewable and electricity increased as well as fossil fuels such as natural gas and lignite burning, substituting for nuclear power.[18]

Renewable electricity

Wind turbines in Baltic Sea in 2013

Germany has been called "the world's first major renewable energy economy".[27][28] Renewable energy in Germany is mainly based on wind, solar and biomass. Germany had the world's largest photovoltaic installed capacity until 2014, and as of 2016, it is third with 40 GW. It is also the world's third country by installed wind power capacity, at 50 GW, and second for offshore wind, with over 4 GW.

Chancellor Angela Merkel, along with a vast majority of her compatriots, believes, "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".[29] The share of renewable electricity rose from just 3.4% of gross electricity consumption in 1990 to exceed 10% by 2005, 20% by 2011 and 30% by 2015, reaching 36.2% of consumption by year end 2017.[30] As with most countries, the transition to renewable energy in the transport and heating and cooling sectors has been considerably slower.

More than 23,000 wind turbines and 1.4 million solar PV systems are distributed all over the country.[31][32][when?] According to official figures, around 370,000 people were employed in the renewable energy sector in 2010, particularly in small and medium-sized companies.[33] This is an increase of around 8% compared to 2009 (around 339,500 jobs), and well over twice the number of jobs in 2004 (160,500). About two-thirds of these jobs are attributed to the Renewable Energy Sources Act.[34][35]

Germany's federal government is working to increase renewable energy commercialization,[36] with a particular focus on offshore wind farms.[37] A major challenge is the development of sufficient network capacities for transmitting the power generated in the North Sea to the large industrial consumers in southern parts of the country.[38] Germany's energy transition, the Energiewende, designates a significant change in energy policy from 2011. The term encompasses a reorientation of policy from demand to supply and a shift from centralized to distributed generation (for example, producing heat and power in very small cogeneration units), which should replace overproduction and avoidable energy consumption with energy-saving measures and increased efficiency. At the end of 2020, Germany had 2.3 GW⋅h of home battery storage, often in conjunction with solar panels.[39]

Transmission network

Grid owners included, in 2008, RWE, EnBW, Vattenfall and E.ON. According to the European Commission the electricity producers should not own the electricity grid to ensure open competition. The European Commission accused E.ON of the misuse of markets in February 2008. Consequently, E.ON sold its share of the network.[40] As of July 2016 the four German TSOs are:

In Germany, there also exists a single-phase AC grid operated at 16.7 Hz to supply power to rail transport, see list of installations for 15 kV AC railway electrification in Germany, Austria and Switzerland.

Special features of German transmission network

edit

There are some special features in the transmission network of Germany. Also they have no direct influence on operation, they are remarkable under technical viewpoints.

Garland-type communication cables

edit

Many powerlines in Baden-Württemberg, which were built by Energie-Versorgung-Schwaben (EVS, now part of EnBW) are equipped with a communication cable, which hangs like a garland on the ground conductor. Some of these lines have also a second communication cable hanging on an auxiliary wire, which is usually fixed on the pinnacle of the pylon below the ground conductor. Such devices are usually installed on lines with voltages of 110 kV and more, but there existed also a 20 kV-line near Eberdingen, which had a communication cable fixed like a garland on a conductor rope. Although communication cables fixed like a garland where replaced in the last decades by free-hanging communication cables many of these devices are still in use. If a downlink of the communication cable from the suspension level to the ground is necessary, which is for example the case at amplifier stations, lines built by former Energie-Versorgung-Schwaben (EVS) use therefore a cable in the centre of the tower strung by a pond instead of a cable fixed at the tower structure. This construction type can be found as well on lines using garland-type communication cables as on lines using freely span communication cables.

Powerline crossings of Elbe river near Stade

edit
 
Elbe Crossing 1 (center) and 2 (right, one mast only)

There are two powerline crossings of the Elbe river near Stade, whose pylons are among the tallest structures in Europe.

Elbe Crossing 1 is a group of masts providing an overhead crossing of a 220 kV three-phase alternating current electric powerline across the River Elbe.[41] Constructed between 1959 and 1962 as part of the line from Stade to Hamburg north, it consists of four masts. Each of the two portal masts is a guyed mast 50 metres (160 ft) in height with a crossbeam at a height of 33 metres (108 ft). One of these masts stands on the Schleswig-Holstein bank of the Elbe and the other on the Lower Saxony bank. Two identical carrying masts 189 metres (620 ft) in height, each weighing 330 tonnes (320 long tons; 360 short tons), ensure the necessary passage height of 75 metres (246 ft) over the Elbe. One stands on the island of Lühesand, the other in the Buhnenfeld on the Schleswig-Holstein side.

Because of the swampy terrain, each mast's foundation is built on pilings driven into the ground. The Lühesand portal mast rests on 41 pilings and the one on the Buhnenfeld on 57. In contrast to the usual construction of such lattice-steel transmission towers, the direction of the line passes diagonally over the square ground cross section of the pylon, resulting in savings in material. The two crossbeams for the admission of the six conductor cables are at a height of 166 metres (545 ft) and 179 metres (587 ft). The mast on the Buhnenfeld bears at a height of 30 metres (98 ft) a radar facility belonging to the Water and Navigation Office of the Port of Hamburg. Each portal mast has stairs and gangways for maintenance of flight safety beacons, and has a hoist for heavy loads.

Elbe Crossing 2 is a group of transmission towers providing overhead lines for four 380 kV three-phase alternating current (AC) circuits across the German river Elbe.[42][43] It was constructed between 1976 and 1978 to supplement Elbe Crossing 1, and consists of four towers:

  • A 76-metre-tall anchor pylon located in Lower Saxony, on the Elbe's southern banks.
  • Two carrying pylons, each 227 metres (745 ft) tall. One is located on the island of Lühesand and the other is near Hetlingen in Schleswig-Holstein, on the northern shore.
These pylons are the tallest pylons in Europe and the sixth tallest of the world. They stand on 95 piers because of the unfavorable building ground. The base of each pylon measures 45 by 45 metres (148 ft × 148 ft) and each pylon weighs 980 tonnes (960 long tons; 1,080 short tons). Crossbeams, which hold up the power cables, are located at heights of 172 (564), 190 (620) and 208 metres (682 ft). The crossbeams span 56 metres or 184 feet (lowest crossbeam), 72 metres or 236 feet (middle crossbeam) and 57 metres or 187 feet (highest crossbeam). Each pylon has a self-propelled climbing elevator for maintenance of the aircraft warning lights; each elevator runs inside a steel tube in the centre of the mast, around which there is a spiral staircase.
  • A 62-metre-tall (203 ft) anchor pylon on the Schleswig-Holstein side.

The enormous height of the two carrying pylons ensures that the passage height requirement of 75 metres (246 ft) over the Elbe demanded by German authorities is met. The height requirement ensures that large ships are able to enter Hamburg's deep-water port.

Electricity pylons

edit
 
Donaumast pylon

Unlike in most other countries, there are only few three-level or delta pylons. Instead, two-level lattice pylons called de:Donaumast are widely used. These carry two cables on the upper and four cables on the lower crossarm. Particularly in eastern Germany one-level pylons were used too. Power lines with less than 100 kV mostly run underground today. Unlike in the USA and many other countries, roadside medium-voltage overhead lines do not exist.[44]

Other features

A 302 metres tall cooling tower of Scholven Power Station at Gelsenkirchen, which is used by four units of these thermal power station is equipped with three booms carrying the conductors of a 220 kV-circuit leaving one of these units.

 
Pylon with observation platform near Hürth (2005)

From 1977 to 2010 a 74.84 metres high strainer of powerline Oberzier-Niedersechtem was equipped with a public observation deck in a height of 27 metres, which was accessible by a staircase. After too much vandalism occurred, which endangered also the integrity of the pylon, this observation deck was removed.

 
Radio relay tower on Goose Neck

As in many other countries, power companies in Germany use radio relay links for data transmissions. In most cases the antennas used therefore are installed on lattice towers, but at some sites concrete towers are used for this purpose. The 87 metres tall radio relay tower on Goose Neck mountain (German: Gänsehals) near Bell is the only of these towers equipped with a public observation deck. It is situated in a height of 24 metres and accessible by a staircase.
