The Institute for Energy Management (ifem) at Mittweida University of Applied Sciences, in collaboration with exceeding solutions GmbH from Halle, has launched the BRIDGER research project, which got off to a successful start on 1 January 2024. The aim of this project is to develop an innovative metering system designed to revolutionise the billing of electricity supplies in blocks of flats. This represents a decisive step in the energy transition, particularly with regard to the use of roof space for photovoltaic systems.
Professor Ralf Hartig, the project leader, explains that whilst the installation and billing of photovoltaic systems in detached houses works without any problems, the situation in blocks of flats is more complex. Whilst the existing ‘tenants’ electricity’ model offers a solution, it presents challenges that can be particularly off-putting for landlords. These include the complexity of energy metering, which becomes necessary when landlords act as energy suppliers.
BRIDGER’s aim is to develop an innovative solution that enables the precise allocation of electricity consumption and generation through the use of virtual meter registers. Using blockchain technology, this system enables flexible and fair billing and allows tenants to enter into contracts with both their landlord and external electricity suppliers simultaneously. This innovation reduces the financial risk for landlords whilst encouraging tenants to opt for cheaper and more environmentally friendly PV electricity. It also promotes more efficient consumption patterns and reduces the strain on the electricity grid. Furthermore, BRIDGER opens up new possibilities for the installation of photovoltaic systems on blocks of flats and can also be expanded to include other applications, such as electric vehicle charging points.
By the end of the project on 31 December 2024, the team plans to develop a fully functional demonstrator to demonstrate the system’s feasibility. This demonstrator will also serve as a real-world laboratory for the partner exceeding solutions, enabling them to demonstrate the system’s practicality and benefits to potential customers.
The project participants have already discussed the next steps at a kick-off meeting in Halle and are optimistic about the project’s future. With BRIDGER, Mittweida University of Applied Sciences and exceeding solutions GmbH are setting new standards in energy billing and making an important contribution to promoting sustainable energy sources and supporting the energy transition.
