SWE Energie GmbH supplies the city of Erfurt with electricity and heat via two plants: the combined heat and power plant on Iderhoffstraße, which has a peak-load boiler for district heating; and secondly, the Erfurt East combined cycle power plant. Through coupled production, the modernized Erfurt East plant saves 180,000 tons of CO₂ per year compared to separate production. With an average fuel utilization rate of 83% and a maximum efficiency of 90%, it is an outstanding example of a sustainable model.
SWE Energie GmbH’s plants have been operated using T3000 for a long time. For legacy reasons, three T3000 systems with different versions of the T3000 control system were used in the plants, and extensive services will soon no longer be available for one of these versions. Therefore, SWE decided to comprehensively upgrade the entire control system to Omnivise T3000 R9.2.
In order to keep the plants efficient and sustainable, an end-to-end I&C system for all turbines and plant components was needed, ensuring long-term support and easy maintainability.
For SWE Erfurt, it is crucial that its control system is always up to date and fulfills future requirements for critical infrastructure. An IEC 62443-certified system that offers advanced cybersecurity enables optimal protection of power generation facilities and is the basis for meeting KRITIS requirements with which SWE’s generation units must comply.
