Enschede’s district heating most sustainable in the Netherlands

Sustainable heat networks play an important role in the replacement of natural gas in the future. Enschede’s heat network is leading the way, according to Bureau CRG (Database of Controlled Quality Declarations and Equivality Declarations) and has been named the most sustainable heat network in the country. Ennatuurlijk and Twence provide households and businesses in Enschede with sustainable heat.

In short

  • For a sustainable future, we must find alternatives for heat from natural gas
  • Twence and Ennatuurlijk supply sustainable heat from biomass in Enschede
  • Enschede’s heat network has been named the most sustainable in the Netherlands!

Global Goal

The sustainability of a heat network is expressed in the EOR (Equivalent Generation Efficiency). This factor shows the relation between the heat supplied and the use of fossil fuels. Both the primary and secondary network of Ennatuurlijk have an EOR of 600 per cent. This means that 80 per cent less fossil energy is needed to produce and provide enough heat to the connected households and companies.


The EOR is determined by calculating all contributions to the grid’s energy consumption and loss. This includes the generation of heat, the loss of heat during transport, and generation efficiency. Heat suppliers can record the EOR in a CRG quality declaration. This offers benefits to companies, housing associations and governments because it shows the energy performance of affiliated companies and homes.

Sustainable society

“We are proud that a recognised quality declaration now also confirms that the heat network in Enschede has an important contribution to reducing climate change”, says Erik Stronk, managing director of Ennatuurlijk. “Our heat network in Enschede is the most sustainable in the Netherlands. That greatly encourages us to develop this further and set up new collaborations.” Ennatuurlijk is working on a more sustainable society together with the municipality, housing corporations, residents and other parties in Enschede. At the moment, 8.000 homes and businesses in Enschede are connected to the Ennatuurlijk heat network.

Twente biofuel

The sustainable heat, produced from biomass, is supplied by Twence. The fuel for the biomass power plant consists of waste wood, such as wood that is left over from constructions and renovations and can no longer be reused. Since April 2018, a six-kilometre-long heat pipe has been used to expand the heat network. A total of 40,000 households and businesses in Enschede can be supplied with sustainable heat.

Sustainable alternative

“We are taking an important step towards more sustainability in Enschede with the heat network and its expansion”, says Marc Kapteijn, general manager of Twence. “We have enough heat available, and we can provide even more households and businesses with a sustainable alternative through strong partnerships in the region. A beautiful example of the energy transition in the region of Twente.”
