Continuing a successful partnership: A new combined cycle power plant gives Evonik a future-viable power supply


• Siemens Energy delivers another highly efficient combined cycle power plant to Marl
• Evonik replaces old backup gas power plant
• Siemens Financial Services arranges customized financing

Siemens Energy is building another highly efficient combined cycle power plant for the specialty chemical company Evonik at its largest industrial location in Marl, North Rhine-Westphalia, Germany. Consisting of one SGT-800 gas turbine, one SST-400 steam turbine, and two generators, the plant will produce power and heat with 90 megawatts of electrical capacity and 220 megawatts of thermal capacity. It will go into operation in 2022 replacing a backup gas power plant. Along with the power plant components, Siemens Energy is also supplying the SPPA-T3000 control system for controlling the cutting-edge plant. A long-term service agreement between Siemens Energy and Evonik will ensure the availability of the power plant and its components.
“Evonik produces sustainable and efficiency-increasing products. That is how we make a significant contribution to reducing CO2 emissions. Overhauling and retrofitting our energy infrastructure represents another way in which we are helping lower the amount of CO2 emissions,” says Rainer Fretzen, chair of the management board of Evonik Technology & Infrastructure.

“We are pleased to have won this contract. Marl VII is another milestone on the road to energy transition supported by our state-of-the-art power plant technologies, generating electricity with an overall efficiency of more than 93 percent. Siemens Energy supports the emission goals of our long-term partner Evonik, and this project will build upon our trusted collaboration,” explained Dr. Jochen Eickholt, Member of the Executive Board of Siemens Energy.

Siemens Energy will develop and build the highly efficient power plant turnkey project as the general contractor. Siemens Financial Services and the KfW IPEX-Bank will fully finance the new plant during the construction phase and after commissioning with a project volume in the lower triple-digit million Euro range.
