The wastewater treatment plant of the Ager-West wastewater association in Attnang-Puchheim has significantly expanded its photovoltaic system. The original PV system installed in 2019 had a maximum output of 100 kilowatts. This has increased to 400 kilowatts as a result of the expansion. Together with the two combined heat and power plants, the association’s sewage treatment plant now generates 1.6 million kilowatt hours per year. This means that the entire electricity requirement of the sewage treatment plant can be covered. The excess is fed into the grid.
The heart of the entire system is the intelligent control, which saves biogas during the day and in the evening hours, when the PV system is not supplying electricity, supplies the sewage treatment plant with electricity via the combined heat and power plants.
The Ager-West wastewater association consists of the municipalities of Vöcklabruck, Attnang-Puchheim, Regau, Timelkam, Ottnang, Wolfsegg, Aurach, Ungenach, Zell a. P., Manning, Pilsbach, Pühret and Desselbrunn.
