Price increase for Frankfurt: District heating up to 36% more expensive from July!

Mainova AG has announced that it will significantly increase district heating prices from July 2025.

The modernization of the West thermal power plant, which will cost around 350 million euros, is part of this strategy. This switch to gas-based and later hydrogen-capable operation is expected to save around 400,000 tons of CO₂ annually from 2027.

Restructuring of the energy supply

In order to achieve the climate goals, Mainova is planning numerous measures. This includes the planned construction of a biomass power plant that will supply former gas customers, as well as the laying of around 300 kilometers of new district heating pipes in Frankfurt.

In the long term, Mainova aims to make the heating market in Germany climate-neutral by 2045.
