Government on route to ‘Zero’ with renewable energy in the Netherlands


  • Cogeneration is the most efficient way to generate power, achieving efficiencies that exceed 90 percent, and offering significant energy savings when compared to the supply of electricity and heat or steam from conventional power stations and boilers.​
  • CHP is a proven technology that reduces harmful emissions (like CO2) into the environment; similar applications have achieved 15 – 40 % reductions in carbon emissions.​
  • NOx emissions ranging between 2 and 8 ppm.

The Opportunity

Water treatment plants in the Netherlands utilize sludge residue in a digester to generate biogas. This biogas is then harnessed in a Combined Heat and Power (CHP) system, allowing the plants to produce their own electricity and supply the necessary heat for the digestion process.

Waterschap Brabantse Delta, one of the largest Water Authorities in the Netherlands, faced a challenge: replacing three outdated CHP units located at two different sites, which had exceeded their operational lifespan. Recognizing the urgency of the situation, WBD initiated a thorough reassessment and issued a public tender with specific requirements.

First and foremost, the new CHP units were expected to meet stringent efficiency standards, both electrically and thermally, in order to be considered for the project. Secondly, the supplier was required to handle all aspects of the project, adhering to a comprehensive one-stop-shop principle. This streamlined approach ensured that the Water Authorities had a single point of contact throughout the entire process.

Lastly, WBD sought an innovative solution to minimize emissions. As a government entity, they aimed to set an example by adopting environmentally friendly practices.

Given the public nature of the tender, the assessment process was conducted objectively. The final decision was predominantly influenced by the extent to which the proposals fulfilled the aforementioned criteria.

The Solution

The choice of acquiring Guascor G-24HM units was primarily due to the the efficiency of the generator set in conjunction with a flue gas cleaner and extensive experience of Dordtech with various types of fuels, particularly biogas.

The three installations have been successfully installed and operational for several months now. Achieving a total efficiency of almost 90%, including the reclaimed energy from the exhaust gasses (at 180ºC), and with NOx emissions ranging between 2 and 8 ppm, the system has surpassed expectations.

Dordtech, an official distributor of Guascor Energy, serves as the complete supplier and maintenance provider. They handle everything from the biogas pretreatment system to their specially designed exhaust gas cleaner. This, combined with their expertise in Guascor Energy technology, makes them the ideal partner for these projects
