At a glance

Development, construction and operation of a biomass district heating network for hot water supply and heating in Guadalajara, with a demand of 100GWh/year for residential, private and public buildings.



This district heating project uses biomass from wood waste for residential heating, reducing dependence on fossil fuels, CO2 emissions and air pollution through the use of gas cleaning systems. The project supports sustainable forest management with PEFC certification, which guarantees that biomass comes from sustainably managed forests and that the entire biomass supply chain meets stringent environmental, social and economic criteria. This includes criteria related to forest management, biodiversity conservation, worker safety and community engagement.


Residential consumers benefit from this technology by reducing installation and maintenance costs, compared to standard heating systems, while offering competitive kWh/price, with lower volatility compared to fossil fuels. Society also benefits from reduced dependence on fossil fuels and the need to import fossil fuels.

How much

Centralised energy production from 31,500 tonnes/year of pellets leads to a significant increase in energy efficiency (23,200 MWh/year) and a decrease in primary energy demand. 1.13 million tonnes of CO2e emissions are avoided.

Core SDGs


Inadequate treatment and conversion of biomass can lead to harmful pollution, such as particulate emissions. However, the installation of gas cleaning systems considerably limits these emissions.
