The Vienna Model
With the Vienna Model, Wien Energie has chosen to take a path that enjoys considerable international renown and which shows how a metropolitan area such as Vienna can be efficiently supplied with energy.
The Vienna Model is based on saving primary energy by using waste heat. As much as three million tonnes of CO2 is saved every year thanks to the Vienna Model and its components. The waste heat from electricity produced in the calorific power plants is used for district heating. This so-called co-generation technology (combined heat and power, CHP) makes it possible to combine the production of electricity and district heating while making full use of the fuel’s energy content.
Using highly efficient co-generation technology requires a high-performance district heating network. Around one third of district heat that is fed into Vienna district heating network spanning some 1,200 km is produced from thermal waste recycling.
Core elements of the Vienna Model
- Producing electricity and heating together in an efficient process known as co-generation.
- Using energy from thermal waste disposal.
- Promoting the use of renewable energy sources.
- Comprehensive energy advice on improving efficiency.
- Decentralised types of production such as citizen solar power plants and technology combinations for solar power and geothermal energy green heating products.
