Combined heat and power generation (CHP)

Decentralised heat and power provision is proving increasingly relevant. Viessmann offers solutions that can contribute towards levelling out the volatility of electricity supply from renewables.

Wind farms and photovoltaic plants were built in large numbers to replace nuclear power stations and conventional large scale power stations. However, as the availability of these renewables fluctuates and, consequently, cannot be scheduled, controlled combined heat and power plants (CHP) have become important components in the push towards a successful energy transition. This development is led by the political target of increasing the share of power generated by CHP plants to 25 percent by 2020.

Decentralised power generation

Where there are shortages in volatile power generation, micro CHP units and CHP plants can make an important contribution to covering demand. Because this happens locally and the power is generated on site, this also reduces pressure on power grids. Generating your own electricity by means of CHP units is now a viable replacement for drawing power from the grid.

Decentralised, heat bias CHP units

Power is generated in comparatively small units where the heat by-product does not have to be transported over long distances simultaneously (which would incur heat loss), but can be used directly on site. There are also no losses arising from power distribution.

Because of their great flexibility combined with maximum efficiency, CHP plants already perfectly complement the more volatile energy sources of sun and wind.
