Project Details

The pumped storage station Snowy 2.0 will connect two existing dams of the Snowy Scheme, Tantangara Dam and Talbingo Dam, through underground tunnels and an underground power station with pumping and generating capacity.

The underground power station will house six reversible Francis-type pump turbines. The capacity of the plant is designed for 2.000 megawatts and allows 175 hours of storage. The first power out of Snowy 2.0 is expected early in 2024. The project can thus make a significant contribution, both to grid stabilization and to the further expansion of power generation from renewable energy.

The Voith order includes the supply of six reversible pump turbines, each with a rated output of 333 megawatts, three of which are variable speed.I addition the order includes six motor generators, the auxiliary systems and the complete power plant automation.

All Purchasing activities will be executed by Purchasing Departments of Voith Hydro Germany and China and will take place from calendar year 2019 until 2026.

The Voith Group is a global technology company. With a broad portfolio of systems, products, services and digital applications, Voith sets standards in the markets of energy, oil & gas, paper, raw materials and transport & automotive. Founded in 1867, the company now has more than 19.000 employees, sales of 4.2 billion Euros and locations in over 60 countries worldwide and is thus one of the largest family-owned companies in Europe.

The Group Division Voith Hydro is part of the Voith Group and a leading full-line supplier as well as trusted partner for equipping hydropower plants. Voith develops customized, long term solutions and services for large and small hydro plants all over the world. Its portfolio of products and services covers the entire life cycle and all major components for large and small hydro plants, from generators, turbines, pumps and automation systems, right through to spare parts, maintenance and training services, and digital solutions for intelligent hydropower.

The Future Generation Joint Venture (a Joint Venture between Salini Impregilo, Clough and Lane) and the technology group Voith signed the contract at the beginning of April 2019. Operator of the plant is Snowy Hydro Ltd.

With the six units, Snowy 2.0 will achieve a total output of 2,000 megawatts and provide the national electricity with 175 hours of continuous large-scale storage. The project can thus make a significant contribution, both to grid stabilization and to the further expansion of power generation from renewable energy.
