Wien Energie harnesses the power of the sun.

In order to achieve Austria’s climate target of only consuming electricity from renewable energy sources by 2030, the use of photovoltaics needs to be expanded to as much as 11 TWh, by erecting PV installations both on open spaces and on the roofs of buildings. We will invest a total of EUR 480 million in adding 600 MW of photovoltaic capacity by 2030, turning Vienna into a city of solar power and cutting CO2 emissions by almost 200,000 tonnes every year.

Liesing solar power plant

Our solar power plant in Vienna’s Liesing district not only produces CO2-free electricity, but also provides the optimum environment in the city for species requiring protection. By building the system and caring for vegetation in a particular way, plants and animals – such as bees, grasshoppers or field hamsters – can really thrive.

PV citizen participation

Our citizen solar power plants enable us to offer people a way of participating financially in PV systems, who in turn benefit from a secure investment and favourable electricity tariffs, while promoting the expansion of renewable energy in the city and cutting CO2 emissions.

Solar roof on Haus des Meeres

As part of the refurbishment of the Haus des Meeres, Wien Energie is installing a solar roof consisting of 202 photovoltaic modules with a total output of at least 63 kWp. What is unique about this new solar roof is the use of special bifacial glass-glass solar modules which generate power not only from above but also from below.

Smart drones

Inspections are an important part of the work to ensure that technical facilities remain efficient and able to function for a long period of time, and drones are increasingly being used for this purpose, making it possible for solar power plants, wind turbines and district heating pipelines to be maintained faster, cheaper and more reliably.

Viertel Zwei

Wien Energie is trialling aspects of future urban life by supporting innovative mobility, energy and living concepts in the VIERTEL ZWEI urban development area, in doing so also creating Austria’s first energy community. The residents trade self-generated solar power among themselves using blockchain technology.
