ANDRITZ to supply hydro- and electro-mechanical equipment for the new Abdelmoumen pumped storage hydropower plant, Morocco

GRAZ, MARCH 6, 2018. International technology Group ANDRITZ has received an order – as part of a consortium – from l’Office Nationale de l’Électricité et de l’Eau potable (ONEE) for supply of hydro- and electro-mechanical equipment for the new Abdelmoumen pumped storage hydropower plant located on the River Issen in Taroudant Province, about 140 km southwest of Marrakech, Morocco. The order value for ANDRITZ is over 120 million euros. Construction work will start in the first half of 2018 and is expected to be completed in 2022.

ANDRITZ’s scope of supply comprises design, manufacturing, delivery, installation, supervision, and commissioning of two 175 MW reversible pump turbines, motor generators, and electrical power systems. The consortium leader, the French company VINCI CONSTRUCTION GRANDS PROJETS, will perform all of the important civil engineering work for the project. Both companies are combining their expertise to jointly realize the technically challenging 3 km steel-lined waterway, consisting of a 2 km-long penstock, more than 700 m of tunnels made of sections of between 3.5 and 5 m in diameter, and three shafts up to 60 m in height.

To provide a reliable base for the design of the pump turbines, ANDRITZ conducted broad research and model testing activities. Operating under the outstanding, high net head of about 554 m, the ANDRITZ design ensures that the two pump turbines are able to accommodate 20 rapid mode changes per day and at the same time meet both the high efficiency and reliability requirements for many years to come.

Abdelmoumen will cover peak-load energy demands and provide rapid response power to regulate the Moroccan grid.
