Project Description

A savings account on the roof

The energy system transformation requires the involvement of citizens. Our citizen solar power plants enables us to offer people a way of participating financially in photovoltaic 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. In this way, individuals can help to secure a sustainable supply of energy for the future. So far, over 10,000 people have invested more than EUR 37 million in 27 solar power plants. Since 2012 120,000 megawatt hours of green electricity have been produced, saving around 40,000 tonnes of CO2.

Project details

Wien Energie has already built a number of citizen power plants in Vienna and Lower Austria. We construct, plan and operate the plant, feed the green electricity into the grid and cover all the expenses incurred. The participating citizens benefit from having a secure investment and being able to use of green electricity as well as promoting the expansion of renewable energies.

Investing in a solar power plant transforms citizens from passive energy users to active prosumers contributing to the energy system transformation. Not only does a PV system protect the environment, but it also improves the quality of life for people living in a city. Moreover, investing in a solar power plant is a wise, sustainable and safe way to invest your money because the compensation received is very attractive when compared to the conditions available on the capital market.

Wien Energie offers different investment models:

  • The ‘Sale-and-lease-back’ model enables individual panels of a PV system to be purchased. Wien Energie then leases this share (panel) back from the buyer, for which the latter receives annual compensation for their contribution.
  • The ‘Tenant participation’ model enables people living in residential buildings to invest in a PV system on their own roof. Tenants can buy panels for which compensation is paid at an interest rate of 1.75 percent over a term of up to 25 years. On top of this, the tenants are supplied with solar power from the roof of their own building.
  • The ‘Voucher’ model, offered in cooperation with SPAR, involves Wien Energie equipping SPAR buildings with PV systems. SPAR customers can support the construction and, in return, receive shopping vouchers by way of compensation every year.

Wien Energie’s citizen power plants are not only popular among the general public, but are also loved by the environment, having generated almost 40,000 megawatt hours of green electricity since 2012. This is equivalent to the power consumption of 440,000 refrigerators and saving over 15,000 tonnes of CO2 every year. When put together, the citizen solar power plants cover an area the size of 19 football pitches.”

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.

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.
