• Vienna is systematically expanding renewable energy use, planning 44 photovoltaic plants on public transport roofs by end of 2026.
  • The city launches a new €7 million incentive package for innovative solutions such as facade PV systems and green solar roofs.
  • The plants will produce up to 7.7 million kWh annually, equivalent to about 550,000 km of subway travel.
  • The generated energy is used on-site for metro stations, lighting, and escalators.
  • The project is part of the city’s strategy to reach 800 MW installed capacity by 2030.
