Austria had 421.7 MW of photovoltaics at the end of 2012, 234.5 MW of which was installed that year. Most of it is grid connected.
In 2009, the site of Zwentendorf power station became Austria's largest solar power station with an investment of 1.2 million Euro, with the addition of 1000 photovoltaic panels. Zwentendorf was intended to be Austria's first nuclear power plant, but after a vote in 1978 prohibiting nuclear power in Austria, was never completed.
In September, 2011, Austria's largest solar power station, 2 MW, was under construction in the Niedere Tauern mountain range.
Photovoltaic deployment in Austria had been rather modest for many years, while in other European countries, such as Germany, Italy or Spain installations were booming with new records year after year until 2011. The tide has turned in 2012. New PV installations jumped to more than 200 megawatt per year in Austria in an overall declining European solar market. The European Photovoltaic Industry Association forecasts, that Austria, together with other midsized countries, will contribute significantly to European PV deployment in the coming years.
