In the context of a feasibility study, all kinds of variants for refurbishing Fenne CHP plant were analyzed, among other things the conversion to natural gas, biomass, retrofitting a gas turbine, and erecting a new combined-cycle plant:

• Checking the technical feasibility and creating a concept
• Thermal calculations
• Determining CAPEX/OPEX
• Scheduling
• Operation management concept
• Clarifying the concept by orientation inquiries and supplier conversations regarding electrolysis and compressor
• Approvability
• Funding
• FGD plant assessment based on new SOx limit of 200 mg/Nm³dry daily average
• Creating retrofitting concepts for optimizing FGD plants
