The storage power plant project, another storage lake and a pumped storage power plant are being built as the second upper stage of the existing Sellrain-Silz power plant group. With this upper stage, the overall efficiency of the power plant group in electricity generation can be sustainably increased.
The additional storage volume increases the flexibility and functionality of the overall system. More available water enables electricity to be produced over a longer period of time; In phases with a lot of generation from solar and wind power, more energy potential is therefore stored in the large lakes at high altitude.
The planned Kühtai storage facility will not only store water for pump circulation. By capturing water in the rear of the Stubai Valley and in the Sulz and Winnebach valleys, an additional 260 million kWh of electricity can be generated from natural inflow alone.
Length of the bypass system: around 25 km from the rear Stubai Valley to Kühtai
Catchment area: around 68 km2
Electricity generation from nat. Inflow: 260 GWh / year
The Kühtai 2 power plant, including the headrace, connects the Finstertal and Kühtai reservoirs. The cavern excavated for this purpose is located at a depth of 174 m below the surface. The power plant is designed for combined turbine and pump operation. Up to 90 m3 of water per second will flow through the two machine sets.
The cavern has connections to the outside via an access tunnel and a drainage tunnel. Only the portal of these two tunnels are visible in the area.
AFRY''s assignment covers the execution design of the main caverns including structural calculations, coordination with EM parts, preparation of formwork and reinforcement drawings and a 3-D coordination model of the main structures of the PSPP. The 3-D Model form the basis for the incorporation of the system in a BIM Model.
The overall schedule for AFRY''s services is about 66 months.
"This is a continuation of AFRY''s outstanding experience in the development and design of PSPP globally.
"We are very pleased to continue our good co-operation with TIWAG in executing this important project. "
Client: TIWAG – Tiroler Wasserkraft AG

• Pumped Storage Power Plants (PSPP), the world''s ''water battery'', accounts for over 94 per cent of installed global energy storage capacity and retains several advantages such as lifetime cost, levels of sustainability and scale. The existing 161,000 Megawatts (MW) of pumped storage capacity supports power grid stability, reducing overall system costs and sector emissions
• AFRY is one of the largest hydropower consulting engineering companies globally, ranked No 4 in the ENR Global Sourcebook 2020

By the end of 2016 Austria already fulfilled their EU Renewables Directive goal for the year 2020. By 2016 renewable energies accounted for 33.5% of the final energy consumption[2] in all sectors (heat, electricity, mobility). The renewable energy sector is also accountable for hosting 41,591 jobs (full-time equivalent) and creating a revenue of 7,219 million euros in 2016.
87% of Austria''s electricity generation was produced by renewable sources in 2023, the second highest in the EU.[3]
Decarbonization means a drastic reduction of carbon emissions and the replacement of fossil fuels by renewable energy sources. This will only be economically and technically possible through linking power, heat and mobility into an integrated energy system (sector coupling). It is not only in the field of electricity, but also to find appropriate measures in the other sectors to achieve the ambitious goals.[4][5]
The former coalition government consisting of ÖVP and FPÖ have given environment and energy an important role in the new government program 2017–2022. According to both parties an ambitious climate and energy strategy is needed to ensure that the target of 100% renewable electricity by 2030 will be reached.[6][7]
Related to renewable energies there is a law called the Green Electricity Act. The Green Electricity Act regulates the promotion of power generation from wind power, photovoltaics (from 5 kWp), solid, liquid or gaseous biomass, landfill or sewage gas and geothermal energy with feed-in tariffs and hydropower (up to 20 MW) with investment support. Each year, a fixed quota is available for new contracted renewable energy plants; the level of feed-in tariffs is set by ordinance. Financing is provided by a pay-as-you-go system through end consumers.[8]
In the field of energy and climate policy, Austria has committed itself to achieving various objectives. The most important and relevant to the ENERGY2050 strategy process are:
With regard to innovative energy-related technologies Austria has the following strategic documents and plans:
The use of hydropower in Austria has a long tradition. At the beginning of the 20th century, hydropower was mostly used for sawmills, mills and forging hammers. Today it is used to generate hydroelectricity.
Because of its mountainous terrain from being situated in the Alps, Austria has a large share of hydropower resources. The range of hydropower plants installed in Austria goes from small hydro plants with a few kilowatts up to big plants with several hundred megawatts. While the definition of small hydropower may differ by country, in the states of the European Union, small hydropower is up to 10 MW of installed power.[11]
The share of hydropower generation in the Austrian electricity mix in 2017 was 43% from run-of-the-river hydropower plants and 21% from pumped-storage hydropower plants.[12] Together, these two sources deliver 64% of Austria''s electricity needs.
The field of green electricity has experienced a sustained upturn since 2003 thanks to the eco-electricity promotion system. This development will continue in 2017 and a gradual expansion of sustainable power generation will be realized.[13] The share of electricity generated from hydropower increased thanks to this system. 148 large hydro power plants (>10 MW) were built from 2003 until 2016.[14]
Over the next few years, growth will be dominated by the repowering of small hydropower plants of up to 10 MW.[15]There are high potentials above all in the western Alpine federal states and along the Danube in Upper and Lower Austria.[11] The potential of large hydropower plants has been largely exhausted. In the Austrian hydropower industry, there were 6784 employees in 2016. The Austrian hydropower industry generated 2 billion euros in 2016.[2]
Due to the longevity of hydropower plants and the increased penetration of intermittent renewable energy resources, such as solar and wind, in the European electricity system, there is potential for cross-border trade of electricity to convert excess intermittent renewable electricity into potential energy for later use via pumped-storage hydropower plants.
