POWER PLANT EXPANSION KÜHTAI, Austria
TIWAG, a Tyrolean hydropower company, has launched the Kühtai pumped storage plant project, an extension of the existing Sellrain-Silz power plant group. The construction site is in the province of Tyrol, approx. 30 km due west of Innsbruck and approx. 2,000 m above sea level. SWIETELSKY was awarded the contract for the Kühtai extension project’s main construction lot as part of a bidding consortium. The contract has a net value of approx. EUR 425 million. Work is scheduled to be completed at the end of 2026. The expansion of the power plant facilities provides for an additional reservoir in Längental with a capacity of 31 million m³ plus an underground pumped storage plant as a second upper stage. The storage capacity can thus be increased by around 50%, with 216 million kWh more electricity generated per year using the additional water.
