ANDRITZ to supply new spherical valves for Dinorwig power station in North Wales, United Kingdom, one of the largest pumped storage plants in Europe

2021/07/28

International technology group ANDRITZ has received an order from First Hydro Company, UK, covering a contract for the supply of six new spherical valves for the Dinorwig pumped storage plant in Llanberis, North Wales, United Kingdom. First Hydro Company is owned 75% by ENGIE and 25% by Brookfield.

The first two valves will be installed in mid-2023, and the other four in mid-2025.

ANDRITZ's scope encompasses the design, manufacture, supply, installation, and commissioning of six spherical valves with a diameter of 2,500 millimeters and a pressure of 60 bar, including governors and the fire protection system.

With a total installed capacity of about 1,728 MW, Dinorwig is one of the largest pumped storage plants in Europe and provides balancing services including reserve and response. At peak, water flows through the turbines at 360m3 per second - the equivalent volume of a typical 25-meter length swimming pool.

The new ANDRITZ spherical valves will contribute to maintaining the overall availability of the entire plant, which has been in operation for nearly 40 years. Dinorwig plays a vital role in the safeguarding of Great Britain’s national grid.

First Hydro placed great confidence in ANDRITZ as a recognized worldwide specialist for spherical valves. ANDRITZ is proud to be part of the refurbishment project for Dinorwig power station.
