Booking platform for e-car sharing launched in Mainz
Published
From September, UrStrom eG will offer its e-car sharing users a customer-friendly cooperative booking app. The goal is a common e-car sharing platform for energy cooperatives throughout Europe.
Mainz, 23.08.2019 Select, book and open electric cars with your smartphone. These are the functions of the cooperative booking app "e-Carsharing in Bürgerhand", which the UrStrom BürgerEnergieGenossenschaft in Mainz is the first German energy cooperative to use. "The smartphone becomes the car key," says Klaus Grieger, project manager for electromobility at UrStrom eG. The four-language booking app has already been in use for some time at energy cooperatives in Belgium and Spain. "The app is extremely practical," says Klaus Grieger enthusiastically.
After UrStrom eG, other energy cooperatives in Rhineland-Palatinate will use the booking app. "We first want to optimise the app regionally for use in Germany so that we can then attract energy cooperatives throughout Germany to use the joint platform," says Dr Verena Ruppert, Managing Director of Landesnetzwerk Bürgerenergiegenossenschaften Rheinland-Pfalz e. V. (LaNEG) e.V. There are currently eight energy cooperatives working in LaNEG's e-car sharing working group that want to launch local e-car sharing projects or are already doing so. Energy cooperatives can also use the cooperative app to offer companies and municipalities needs-based e-carsharing solutions. The booking platform is the first step towards establishing the cooperative brand "e-Carsharing in Bürgerhand" throughout Germany.
At the end of 2018, citizen energy cooperatives from four European countries founded The Mobility Factory (TMF) as an umbrella cooperative of European e-carsharing cooperatives. TMF provides a professional e-carsharing platform to its members. Currently, all TMF members can use the booking app as licensees and participate in the further development of the system. In the future, the entire value chain in e-car sharing will be in the hands of the cooperatives and thus be user-oriented and independent of purely profit-oriented corporate structures. "The use and further development will remain in the hands of citizens, in the democratic structures of cooperatives," says Michael König, Chairman of TMF.
Currently, about 100 electric vehicles are in use at member cooperatives in Spain, Belgium, the Netherlands and Germany. In three years, there should be at least 1800 vehicles available to all users of cooperative e-car sharing across Europe.
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.
Sharp decline in coal-fired power
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.
Battery storage systems are developing rapidly
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.
Declining exports and exchange electricity prices
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.
A detailed presentation of the data on electricity generation, imports/exports, prices, installed capacity, emissions and climate data can be found on the Energy Charts Server: www.energy-charts.info/downloads/Stromerzeugung_2023.pdf
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.
What makes a sustainable university? Sustainability Council and 50 university administrations, employees and students are developing a sustainability code for universities. The test phase of the beta version of the university code will start in autumn. In autumn 2014, the German Council for Sustainable Development (RNE) held a stakeholder conference on "From Pilot to Standard: Implementing Sustainability in Research, Teaching and Operations" to discuss the implications [...]
The Munich City Council's Committee for Urban Planning and Building Regulations has decided to promote the construction of new, contemporary timber construction projects. This year, the city council will develop another grant programme for construction using wood and other renewable raw materials.
The subsidy programme is suitable both for individual projects and for larger housing estates and neighbourhoods. The aim of the city administration is to ensure that around 50 percent of the buildings on municipal land are constructed using timber.
