Stadtwerke Ludwigsburg-Kornwestheim is building one of the largest solar thermal plants in Germany with a collector area of over 10,000 m². The way is clear for another forward-looking project in Ludwigsburg: Stadtwerke Ludwigsburg-Kornwestheim GmbH (SWLB) has won the funding call for municipal climate protection model projects as part of the national climate protection initiative of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety in Berlin.
Their funding application for the SolarHeatGrid model project for the 'construction and connection of one of the largest solar thermal plants in Germany to an optimised heating network', in which the City of Ludwigsburg is involved as a cooperation partner, was approved. The official handover of the Municipal Climate Protection Model Project grant to Bodo Skaletz, Managing Director of SWLB, took place on 12 May 2017 by Rita Schwarzelühr-Sutter, Parliamentary State Secretary of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety, in the presence of the Lord Mayor of the City of Ludwigsburg and Chairman of the Supervisory Board of SWLB, Werner Spec, and the Lord Mayor of the City of Kornwestheim and Deputy Chairman of the Supervisory Board of Stadtwerke.
"In terms of the amount of funding, our solar thermal project is the front-runner in the ranking of the seven projects that were also approved. The federal government is contributing 10.4 million euros to the realisation of Ludwigsburg's large-scale project, which should inspire imitation throughout Germany," says a delighted Bodo Skaletz, Managing Director of SWLB.
"This renewal of the district heating network with solar heat is particularly forward-looking with regard to the feasibility of municipal heat supply with renewable energies. Swapping fossil for renewable - it works. I congratulate Ludwigsburg on this major high-tech piece of the puzzle, also in terms of CO2 savings and improved energy efficiency," confirms Parliamentary State Secretary Rita Schwarzelühr-Sutter.
"The 'SolarHeatGrid' is an important building block in the implementation of our overall energy concept for Ludwigsburg," explains Mayor Werner Spec. "We are thus significantly expanding our heat supply on a renewable basis and linking it across municipal boundaries. This is entirely in the spirit of sustainable settlement development: as cities, we must continue to commit ourselves locally with all our strength to environmental and climate protection."
The official start of this lighthouse project is 1 June 2017. The model project is scheduled to take a total of three years. As part of the project, the existing Ludwigsburg district heating network, which already provides heat for large parts of the city using mainly renewable raw materials, will be merged with the Rotbäumlesfeld, Technische Dienste Ludwigsburg (Gänsfußallee 21) and Kornwestheim-Nord networks, which are currently still supplied with fossil fuels. The construction of the solar thermal plant in connection with a large heat storage tank, which is to be built at the location of the CHP plant, will additionally feed high-quality, regeneratively generated heat into the expanded interconnected grid. This will further increase the amount of heat from renewable energies. With the help of the heat storage facility, the energy generated will also be available when there is little or no solar radiation.
The base load heat of the fossil-fuelled heating centres of the individual grids can thus be replaced by the largely regeneratively generated heat of the expanded interconnected grid. Approximately five kilometres of new district heating pipes will be laid over the next three years to connect the solar thermal system and the interconnected grid. In addition to the CO2 savings that will be achieved through the growing share of renewable energies in the expanded district heating network, the declared goal of the large-scale project is to increase energy efficiency. "In order to ensure that energy is used as efficiently as possible, it is not only the heat generation and distribution by SWLB that is decisive, but also the consumer side," Skaletz explains and adds: "As part of the network interconnection, measures are therefore to be implemented to reduce the so-called return temperatures, on which the performance of our district heating network depends to a large extent."
SWLB submitted the funding application in November 2016. The project aims to increase the share of renewable energies in the district heating network and to actively promote local climate protection and the energy transition at the local level by reducing CO2 emissions.

Net public electricity generation reached a record share of 59.7 per cent in 2023. The share of the load was 57.1 per cent. This is the result of an analysis presented today by the Fraunhofer Institute for Solar Energy Systems ISE. New records were set for wind and solar power in 2023. In contrast, generation from lignite (-27 per cent) and hard coal (-35 per cent) fell sharply. Photovoltaics stood out in the expansion of generation capacity: at around 14 gigawatts, the expansion was in double digits for the first time and significantly exceeded the German government's statutory climate protection target. Source of the data is the platform energy-charts.info
Photovoltaic systems generated approx. 59.9 TWh in 2023, of which 53.5 TWh was fed into the public grid and 6.4 TWh was used for self-consumption. At around 9 TWh, June 2023 was the month with the highest solar power generation ever. The maximum solar output of 40.1 GW was reached on 7 July at 13:15, which corresponded to a 68% share of electricity generation. In 2023, the expansion of photovoltaics significantly exceeded the German government's targets: instead of the planned 9 gigawatts, 13.2 gigawatts were installed by November; according to preliminary data, this will be more than 14 gigawatts by the end of 2023. This is a sharp increase compared to 2022 (7.44 GW). This means that PV expansion in Germany has reached double digits for the first time.
The Hydropower increased from 17.5 TWh in 2022 to 20.5 TWh. The installed capacity of 4.94 GW has hardly changed compared to previous years.
The Biomass at 42.3 TWh was at the level of 2022 (42.2 TWh). The installed capacity is 9 GW.
In total, the renewable energies approx. 260 TWh in 2023, around 7.2 per cent more than in the previous year (242 TWh). The share of renewable energy generated in Germany in the load, i.e. the electricity mix that actually comes out of the socket, was 57.1 per cent compared to 50.2 per cent in 2022. In addition to net public electricity generation, total net electricity generation also includes in-house generation by industry and commerce, which is mainly generated using gas. The share of renewable energies in total net electricity generation, including the power plants of "businesses in the manufacturing, mining and quarrying sectors", is around 54.9 per cent (2022: 48.2 per cent).
The Load in the electricity grid totalled 457 TWh, around 26 TWh less than in 2022. Due to the high electricity prices and higher temperatures, electricity was probably saved significantly. The increase in self-consumption of solar power is also reducing the load. The load includes the electricity consumption and grid losses, but not the pumped-storage power consumption and the self-consumption of conventional power plants.
After German coal-fired power plants ramped up their production in 2022 - due to the outage of French nuclear power plants, but also due to the distortions in the electricity market caused by the war in Ukraine - their share fell significantly in 2023. As a result, generation in November 2023 was 27 per cent below the same month in the previous year due to the drop in coal-fired electricity exports, but also because of the good wind conditions.
Overall, production from Lignite for public electricity consumption fell by around 27 per cent, from 105.9 to 77.5 TWh. This is in addition to 3.7 TWh for industrial own consumption. Gross electricity generation fell to the level of 1963.
Net production from Hard coal-fired power plants for public electricity consumption was 36.1 TWh (-35 per cent) and 0.7 TWh for industrial own consumption. It was 21.4 TWh lower than in 2022. Gross electricity generation fell to the level of 1955. Natural gas for electricity generation remained slightly below the previous year's level at 45.8 TWh for public electricity supply and 29.6 for industrial own consumption. Due to the shutdown of the last three nuclear power plants in Emsland, Neckarwestheim and Isar on 15 April 2023, the Nuclear power only contributed 6.72 TWh to electricity generation, which corresponds to a share of 1.5 per cent.
The expansion of fluctuating renewable energies also increases the need for grid expansion and storage capacity. Battery storage systems, which are installed on a decentralised basis to buffer the generation of wind and solar power, are particularly suitable. The private household segment is showing strong growth, as is the case with photovoltaic systems. Overall, installed battery capacity almost doubled from 4.4 GW in 2022 to 7.6 GW in 2023, while storage capacity rose from 6.5 GWh to 11.2 GWh. The capacity of German pumped storage plants is around 6 GW.
After an export surplus of 27.1 TWh was achieved in electricity trading in 2022, an import surplus of 11.7 TWh was recorded in 2023. This was due in particular to the lower electricity generation costs in neighbouring European countries in the summer and the high costs of CO2-certificates. The majority of imports came from Denmark (10.7 TWh), Norway (4.6 TWh) and Sweden (2.9 TWh). Germany exported electricity to Austria (5.8 TWh) and Luxembourg (3.6 TWh).
In winter, electricity exchange prices rose again and CO2-certificates became more favourable. This already led to a balance in November and, in conjunction with high wind power generation, to export surpluses in December. In contrast to its neighbouring countries (Austria, Switzerland, France), Germany also has sufficient power plant capacity in winter to produce electricity for export.
The average volume-weighted day-ahead price Exchange electricity price fell sharply to €92.29/MWh or 9.23 cents/kWh (2022: €230.57/MWh). This puts it back at the 2021 level.

The data basis
This first version of the annual evaluation takes into account all electricity generation data from the Leipzig electricity exchange EEX and the European Network of Transmission System Operators for Electricity (ENTSO-E) up to and including 31 December 2023. The quarter-hourly values from the EEX were energetically corrected using the available monthly data from the Federal Statistical Office on electricity generation up to September 2023. For the remaining months, the correction factors were estimated on the basis of past monthly and annual data. The extrapolated values from October to December are subject to larger tolerances.
This is based on the data for the German Net electricity generation to the public electricity supply. It is the difference between gross electricity generation and the power plants' own consumption and is fed into the public grid. The electricity industry calculates with net figures, e.g. for electricity trading and grid utilisation, and only net electricity generation is traded on the electricity exchanges. It represents the electricity mix that actually comes out of the socket at home.
