Net electricity generation in the first half of 2020: On July 1st, the Fraunhofer Institute for Solar Energy Systems ISE presented the data on public net electricity generation for the first half of 2020, which comes from the Energy Charts data platform. With a share of 55.8 percent of net electricity generation for public electricity generation - i.e. the electricity mix that comes from the socket - renewable energies set a new record. In February their share was even 61.8 percent. Solar and wind energy systems together fed 102.9 terawatt hours (TWh) into the public grid, compared to 92.3 TWh in the first half of 2019. Electricity production from coal, on the other hand, fell sharply: the share of lignite fell to 13.7 percent, hard coal only comes to 6 percent. Wind energy was once again the strongest energy source with a share of 30.6 percent.

The graphic above shows the net electricity generation from power plants that supply public electricity. This is the mix of electricity that actually comes from the socket. The production from power plants of “companies in the manufacturing sector as well as in the mining and quarrying of stones and earths”, ie industrial production for own consumption, is not taken into account in this presentation.

The consequences of the corona pandemic are noticeable

From the second quarter of 2020 onwards, the fall in demand for electricity became noticeable due to the decline in industrial production caused by the corona pandemic. The load fell to 35.3 TWh in June (June 2019: 37.6 TWh), electricity production fell from 47.9 TWh in January to 36.0 TWh in June. Overall, the load in the first half of the year was 234.2 TWh, a significant decrease compared to the 245.7 TWh in the first half of 2019. Electricity production fell by 21.7 TWh compared to the first half of 2019 to 243.8 TWh. Part of this decline is due to exports falling from 20.1 TWh to 7.5 TWh.

Renewable energies driven by strong winds

Photovoltaic systems fed around 27.9 TWh into the public grid in the first half of the year, an increase of 11.2 percent compared to the previous year (25.1 TWh). The solar power systems benefited from the favorable weather conditions, which allowed more than 6 TWh of electricity production per month from April to June.

Wind energy produced around 75 TWh in the first half of 2020, around 11.7 percent higher than production in the first half of 2019 (67.2 TWh). Due to the numerous winter storms, their share even rose to 45 percent of net electricity generation in February. Hydropower produced around 9.5 TWh in the first half of the year, a decrease of 9 percent compared to the previous year (10.5 TWh). Approximately 23.7 TWh were produced from biomass, a slight increase compared to the previous year.

In total, the renewable energy sources solar, wind, water and biomass produced around 136.1 TWh in the first half of 2020 (previous year: 125.6 TWh). The share of public net electricity generation, i.e. the electricity mix that actually comes from the socket, is around 55.8 percent, a sharp increase compared to 2019 (47 percent). The share of renewable energies in total gross electricity generation is over 50 percent for the first time. Gross production also includes the industry's own production (companies in the manufacturing sector as well as in mining and the extraction of stone and earth) as well as the internal losses of conventional power plants. Neither share is fed into the public power grid.

Coal electricity is declining sharply - “Fuel Switch” to natural gas

Net electricity production from nuclear power plants was approximately 30.1 TWh in the first half of 2020, a decrease of 12.9 percent compared to the previous year's level (34.6 TWh). Lignite power plants produced around 33.6 TWh net. That is 19.1 TWh or 36.3 percent less than in the first half of 2019. Net production from hard coal-fired power plants fell by 46 percent to just 14.4 TWh. The sharp decline is due to the increased costs for CO₂ certificates, which averaged 21.91 euros per tonne of CO₂, and the sharp fall in the day-ahead exchange electricity price of an average of 22.94 euros/MWh (compared to 36.83 euros/MWh in 2019). With emissions of around 1 tonne of CO₂ per megawatt hour of coal-fired power generated, coal-fired power plants were no longer economically viable.

Since the price of natural gas halved in the same period (8.03 euros/MWh instead of 16.38 euros in 2019) and natural gas power plants have lower CO₂ certificate costs, a “fuel switch” from coal to natural gas took place.

Gas-fired power plants increased their production to 28 TWh, an increase of 13.9 percent compared to 24.6 TWh last year. In addition to the power plants that supply public electricity, there are also gas power plants in the mining and manufacturing industries that supply their own electricity. These additionally produced around 20 TWh for their own industrial needs.

Net electricity generation in the first half of 2020: On July 1, the Fraunhofer Institute for Solar Energy Systems ISE presented the data on public net electricity generation for the first half of 2020, which are derived from the Energy Charts data platform. With a 55.8 percent share of net electricity generation in public power generation – ie the electricity mix that comes out of the socket – renewable energies set a new record. In February, their share was as high as 61.8 percent. Solar and wind power plants together fed 102.9 terawatt hours (TWh) into the public grid, compared with 92.3 TWh in the first half of 2019. In contrast, electricity production from coal fell sharply: the share of lignite fell to 13.7 percent, while hard coal now accounts for only 6 percent. Wind power was again the strongest source of energy, accounting for 30.6 percent.

The chart above shows the net electricity generation from power plants for public supply. This is the electricity mix that actually comes out of the socket. The generation from power plants of “companies in the manufacturing industry as well as in mining and quarrying”, i.e. industrial generation for own consumption, is not included in this figure.

Consequences of the corona pandemic noticeable

From the second quarter of 2020, the lower demand for electricity became noticeable due to the decline in industrial production caused by the corona pandemic. Load dropped to 35.3 TWh in June (June 2019: 37.6 TWh), while electricity production fell from 47.9 TWh in January to 36.0 TWh in June. In total, the load in the first half of the year was 234.2 TWh, a significant decrease from 245.7 TWh in the first half of 2019. Electricity production fell by 21.7 TWh to 243.8 TWh compared to the first half of 2019. Part of this decline is attributable to the drop in exports from 20.1 TWh to 7.5 TWh.

Renewable energies driven by strong wind

In the first half of the year, photovoltaic systems fed approx. 27.9 TWh into the public grid, an increase of 11.2 percent compared with the previous year (25.1 TWh). The solar power systems benefited from the favorable weather conditions, which allowed more than 6 TWh of electricity to be produced per month from April to June.

Wind power produced about 75 TWh in the first half of 2020 and was therefore about 11.7 per cent above the production in the first half of 2019 (67.2 TWh). Due to the numerous winter storms, its share even rose to 45 percent of net electricity generation in February. Hydroelectricity production in the first half of the year was approximately 9.5 TWh, down 9 percent from 10.5 TWh in the prior-year period. Approximately 23.7 TWh were produced from biomass, a slight increase compared to the previous year.

In total, the renewable energy sources solar, wind, hydro and biomass produced approx. 136.1 TWh in the first half of 2020 (previous year: 125.6 TWh). The share of public net electricity generation, ie the electricity mix that actually comes out of the socket, is approx. 55.8 percent, a sharp increase compared to 2019 (47 percent). The share of renewable energies in total gross electricity generation exceeds 50 percent for the first time. Gross generation also includes the industry's own production (companies in the manufacturing sector as well as in mining and quarrying) and the internal losses of conventional power plants. Both shares are not fed into the public power grid.

Coal-fired power sharply declines - “Fuel Switch” to natural gas

Net electricity generation from nuclear power plants amounted to approx. 30.1 TWh in the first half of 2020, a decline of 12.9 percent compared to the previous year's level (34.6 TWh). Lignite-fired power stations produced approx. 33.6 TWh net. This is 19.1 TWh or 36.3 percent less than in the first half of 2019. Net production from hard coal-fired power stations slumped 46 percent to just 14.4 TWh. This sharp decline is due to the increased cost of CO₂ certificates, which averaged Euro 21.91 per ton CO₂, and the sharp drop in the day-ahead exchange electricity price of Euro 22.94/MWh on average (compared with Euro 36.83/MWh in 2019) . With an emission load of about 1 ton CO₂ per generated megawatt hour of coal-fired electricity, the economic viability of coal-fired power plants was hardly given.

As the price for natural gas halved in the same period (8.03 Euro/MWh instead of 16.38 Euro in 2019) and natural gas power plants have lower CO₂ certificate costs, a “fuel switch” from coal to natural gas took place.

Gas-fired power stations increased their production to 28 TWh, an increase of 13.9 percent compared with the 24.6 TWh in the previous year. In addition to the power plants for public electricity supply, there are also gas-fired power plants in the mining and manufacturing industries to supply their own electricity. These also produced an additional 20 TWh for the company's own industrial needs.
