The municipality of Graefelfing relies on a sophisticated electricity and heat supply on the school campus. Instead of supplying the Kurt-Huber-Gymnasium, the elementary and middle school and the gymnasium and swimming pool that is currently being built with electricity from Bayernwerke via their own house connections, this will in future be done by a single district electricity system. The bundling saves the community around 80,000 euros a year. The investment costs of around 200,000 euros – among other things, a transformer house has to be built for the new system – should have paid for itself after around three years. The local council approved the project.
The new type of power supply has another charm: the planned, biogas-operated combined heat and power plant on campus will supply all buildings with heat. The electricity generated in the process – “actually a waste product,” explains Stefan Schädle from the building authority – plus the electricity generated by the photovoltaic systems on the school roofs and on the new gym and swimming pool, will be used entirely for the campus before the remaining one in summer The rest is fed into the grid. Most of the electricity required on campus is generated in-house.
