Three heating plants with combined gas and steam cycle.

Already in 1989, Papier- und Kartonfabrik Varel invested in its initial gas and steam turbine power plant based on the patented Hutter process of double-cogeneration.

The power plant park provides an independent supply of electricity and contributes to nationwide CO² reduction in addition to the low emissions.

The expansion of the power plant in 2007 resulted in the natural gas as a primary energy source and biogas generated from our process water treatment system to yield a utilisation rate of 92%. This makes the power plant one of the most modern of its kind.

The paper and board mill produces significantly more power than is needed and feeds 5-15 MW into the public grid. Enough to power a medium-sized town like Varel.

  • Combined heat and power generation plant
    The patented method of double cogeneration enables the most efficient utilisation of the primary fuel source natural gas.

    The cogeneration plants Varel 1 (1989) and Varel 2 (2002) were complemented by another powerful thermal power station in 2007. Cogeneration plant Varel 3 features a 90 t Baumgarte high pressure radiant boiler with two upstream Taurus 65 gas turbines of the 6.3 megawatt class.

    The plant can handle uninterrupted operation of 8,600 hours per year with a fuel efficiency of 92%.

  • Biogas
    The biogas mass that accumulates during anaerobic water treatment is used to generate power in our biogas plant. About 9.0 million m³ of biogas are produced annually. This corresponds to approximately 58,000 MWh.

  • Solar energy
    On part of our warehouse we have been operating a photovoltaic system since 2010. The plant has an installed capacity of about 1 MWp and uses up about 18,000 m² of surface area. The electricity produced through solar energy is enough to power the more than 30 electric forklifts, which are operated 24/7, seven days a week.

    In comparison to the average CO² emissions of conventional electricity generation in Germany, about 750,000 kg CO² is saved annually. This corresponds to approximately 6,250,000 kilometres of motorway travelled by a car with CO² emissions of 120 g/km.
