Austria's Power Sources: A Comprehensive Overview

Austria's mountainous geography makes hydropower possible, with the Danube River flowing through the country's largest state, Lower Austria. As a whole, Austria produces around 70% of its electricity via renewables, the highest share in the EU. Lower Austria, which is home to 1.6 million of the country's 8 million people, generates 100% of its electricity from renewable sources, with 63% of its electricity from hydroelectric power, 26% from wind energy, 9% from biomass and 2% from solar.

Hydroelectric power

Austria's mountainous geography makes hydropower a viable option for generating electricity. Hydropower is produced by damming rivers at altitude and then letting the water flow downhill. In 2017, 43% of Austria's hydropower was generated by run-of-the-river hydropower plants, with 21% coming from pumped-storage hydropower plants. Together, these two sources deliver 64% of the country's electricity needs.

Austria's largest state, Lower Austria, which is home to 1.6 million people, gets nearly two-thirds of its electricity from hydropower. This is generated from the Danube, which flows through the state.

Hydropower is a renewable source of energy, and Austria has invested heavily in expanding its use. Between 2003 and 2016, 148 large hydropower plants were built, and in the future, growth will be dominated by the repowering of small hydropower plants of up to 10 MW.

Wind energy

Austria produces around 70% of its electricity via renewables, the highest share in the EU. The country's mountainous geography makes hydropower possible, with 64% of Austria's electricity needs met by run-of-the-river hydropower plants and pumped-storage hydropower plants.

The development of wind energy in Austria has contributed to the country's goal of increasing renewable energy production and reducing its reliance on fossil fuels. Wind energy is a key component of Austria's energy mix, alongside hydropower, biomass, and solar power. The country's investment in eco-electricity and renewable sources has paid off, with Austria leading the EU in terms of the share of electricity produced via renewables.

Biomass

Austria produces around 70% of its electricity via renewable sources, the highest share in the EU. Hydropower, wind energy, biomass and solar provide 100% of electricity for 1.65 million people in Lower Austria, the country's largest state.

The use of biomass for energy has several environmental benefits. It is a renewable resource, meaning it can be replenished naturally, and it helps to reduce greenhouse gas emissions by providing a cleaner alternative to fossil fuels. Additionally, biomass can be produced from waste materials, reducing the amount of waste that goes to landfill.

Austria has invested heavily in renewable energy sources, including biomass. This investment has paid off, with the country now generating a significant portion of its electricity from renewable sources. Biomass plays a key role in this success, and its use is expected to continue growing in the future.

Solar power

Austria generates 70% of its electricity from renewable sources, the highest share in the EU. The largest state in Austria generates 100% of its electricity from renewable sources. Hydropower is the most common renewable source, with 64% of Austria's electricity coming from hydropower plants. Wind energy is the second most common renewable source, with 26% of the largest state's electricity coming from wind.

Austria has invested heavily in renewable energy sources, including solar power. In 2002, the country invested 2.8 billion euros in eco-electricity, which included the development of solar parks. This investment has helped to increase the share of renewable energy in Austria's electricity mix.

Run-of-the-river hydropower plants

Austria's mountainous geography makes hydropower a viable option for generating electricity. In 2017, 43% of the country's hydropower generation came from run-of-the-river hydropower plants, with a further 21% coming from pumped-storage hydropower plants. These two sources alone deliver 64% of Austria's electricity needs.

Run-of-the-river plants can be further categorised into two types: diversion and in-stream. Diversion plants divert a portion of the river through a canal or penstock to the turbine, while the remaining water continues to flow downstream. In-stream plants, on the other hand, use the full flow of the river to turn the turbines. These plants are typically smaller in scale and are often used in remote areas where electricity is needed but the grid infrastructure is lacking.

The use of run-of-the-river hydropower plants has been on the rise in Austria, with a focus on repowering and expanding small hydropower plants of up to 10 MW. This shift towards renewable energy sources has allowed Austria's largest state, Lower Austria, to become self-sufficient in power, generating nearly two-thirds of its electricity from hydropower alone.
