17 green energy generation in Vienna, austria Vienna’s drinking water comes from mountain springs through two long-distance pipelines. The elevation drop allows the gravity flow to turn turbines installed within what are commonly referred to as drinking water power plants (DWPPs), which generate electricity while reducing the water pressure to levels suitable for the city’s drinking water infrastructure. This provides the energy necessary to operate the system itself, as well as surplus electricity which is then sold to utility companies. The use of such energy-generating systems was temporarily suspended in the 1970s due to economic considerations mainly arising from stagnant energy prices. New pipes with valves to control water pressure were installed to bypass the turbines. In the mid-1990s, however, electricity prices recovered and renewable energy resources became increasingly sought in Austria. This led to the re-operationalization of Vienna’s abandoned water turbines and the construction of new plants. The DWPP at Mauer, along the Second Mountain Spring Pipeline, was the first new plant to be constructed, while the older DWPP at Reithof, located along the First Mountain Spring Pipeline, was upgraded to boost its initial capacity of 45 kW (in 1929) to 340 kW. The turbines neither alter water quality nor block water flow to jeopardize reliable water supply. By 2011, more than 65 million kWh electricity was being generated annually by 14 such plants located within and around the city of Vienna, contributing towards achieving the European Community target of a 20% share of energy from renewable sources by 2020 (Directive 2009/28/EC). The city is actively seeking further potential sites for such plants, as well as drawing 17.1 An energy self-sufficient wastewater treatment plant Ebswien, Vienna’s main wastewater treatment plant, purifies approximately 220 million m3 sewage per year. The power used by the plant accounts for almost 1% of the city’s total electricity consumption. Confronted by rising energy costs, however, city officials have turned to innovative approaches to reduce Ebswien’s energy consumption. The plant uses a number of renewable energy technologies, such as hydropower, solar energy (thermal and photovoltaic), wind power and methane, to lessen dependency on carbon-based energy sources and to decrease greenhouse gas emissions. These technologies have been carefully implemented to function in an integrated manner. A turbine installed at the point of discharge, where the treated effluent is drained into the Danube River, generates approximately 1.5 GWh electricity annually. Solar thermal and photovoltaic power units are also built into the compound, and a small wind turbine generates sufficient current to power the exterior lighting. An integrated block heat and power station utilizes approximately 20 million m3 methane that has been recovered during the treatment process, producing 78 GWh electricity and 82 GWh heat output per year. In addition, the plant’s energy consumption has been reduced significantly through process optimization and infrastructural measures such as using energy saving bulbs and efficient heating technologies. As a result of these combined technologies, the Ebswien wastewater treatment plant is not only energy self-sufficient until 2020, but also produces a surplus of approximately 15 GWh electricity and 42 GWh heat output annually. The reduction in greenhouse gas emissions is estimated at approximately 40,000 tonnes per year, equivalent to that of a town of 4,000 inhabitants.
