Sustainable Energy Solution from E.ON for DSM Nutritional Products


  • Contract for decentralized power generation extended for at least 15 years
  • Installation of a new gas and a new steam turbine with a total output of 30 megawatts

DSM Nutritional Products - a global company active in the health, nutrition and materials sectors - and E.ON have announced their intention to essentially modernize the existing distributed power plant at Grenzach-Wyhlen in Baden-Württemberg. The fuel-efficient combined heat and power plant from E.ON has been producing process steam and electricity to manufacture vitamins and carotenoids for more than 13 years. However, the energy demand at the production site has recently changed and the facility is also nearing the end of its lifetime.

As energy partner to DSM Nutritional Products, E.ON developed a modernization concept tailored to the site's long-term needs that will allow further sustainable operation of the combined heat and power plant. The core of the upgraded facility is a new gas turbine with 22 megawatts (MW) of electrical capacity. The heat recovery steam generator will be fully overhauled to allow a highly efficient steam generation by using waste heat from the gas turbine exhaust. Before DSM can use the steam for manufacturing, it flows through a new and more efficient steam turbine that can generate up to 8 MW of electricity during peak hours.

According to Sjef Arets, chairman of the supervisory board at DSM Nutritional Products GmbH in Grenzach-Wyhlen, "The upgraded facility will supply energy to DSM Nutritional Products for 15 years. This long-term agreement also sends a positive signal to the future of the production site located in the region on the borders between Germany, Switzerland and France. The reduction of energy costs by an efficient energy generation is a vital contribution for site’s future viability in a competitive environment."

"For companies in the chemical industry a secure energy supply is of high importance. We feel honored that DSM Nutritional Products is extending our partnership and awarding us a new project. We are also proud of our bespoke solutions contributing to the future security of the site," says Bernd Schumacher, CEO of E.ON Connecting Energies.
