Report: Leipzig Model to integrate PV electricity into the general power supply
Rising electricity prices and climate change pose major challenges for the energy supply. The German government has set itself the target of reducing CO2 emissions by 55 % by 2030 and by 80 to 95 % by 2050 compared to 1990. Sustainable energy supply through renewable energies and energy efficiency plays a key role in this.
The expansion of renewable energy for tenants in particular is an important part of this strategy. One possible sustainable and efficient response to rising electricity prices is the use of solar energy on residential buildings to produce electricity. While photovoltaic systems (PV systems) on roof surfaces are primarily suitable for homeowners, as they can benefit from solar power due to the self-supply privilege, the majority of the population lives in apartment blocks and cannot benefit from this. They generally only have the option of paying attention to energy consumption and efficiency.
In order to find possible solutions, WSL Wohnen & Service Leipzig GmbH carried out a study on tenant electricity, a model with which the electricity generated on site can also be used by the resident tenants. As part of the SPARCS project, which aims to transform existing districts in Leipzig into positive energy districts (PEDs), the Leipzig model was developed, which will be presented in more detail in this report. The Leipzig model is a balance sheet model that aims to integrate PV electricity as a volume component into the general electricity supply through an intermediate virtual power plant.
