“The energy transition can only succeed with a consistent expansion of photovoltaics, hydropower and wind power,” says ASFINAG CEO Hartwig Hufnagl. “With this initiative in Carinthia, we are taking another important step towards achieving our goal of being self-sufficient in electricity by 2030. We will therefore follow up with many more such projects.”
New Solar Power Installation for Ehrentalerberg Tunnel
A new solar power system will be installed at the east portal of the Ehrentalerberg tunnel from spring 2024. More than 2600 solar electric panels with a total output of 1100 kilowatts peak will ensure that the tunnel can be operated in an energy-neutral manner in future. Completion is scheduled for the end of 2024.
Diverted Karawanken Mountain Waters Supply Electricity
Construction work on ASFINAG's third small hydropower plant has already started in 2023. Normally, tunnel seepage water is diverted from a tunnel without being utilised. In the case of the Karawanken tunnel, all this mountain water will be collected and channelled to the north portal, where it will be used to generate energy in a hydroelectric power plant. The mountain water is discharged very evenly throughout the year, which means that it can be expected to operate continuously for 60 years or more. The output of the power plant will be around 470 megawatt hours, which is as much as around 100 single-family homes need per year. The electricity generated will be fed directly into the tunnel. Around 30 per cent of the electricity required – not including ventilation – can be covered by hydropower in future.
