Civil engineering contract awarded for Austria’s 940-MW Koralm pumped-storage plant

Pumpspeicherkraftwerk Koralm GmbH has selected ILF Consulting Engineers and AF-Consult to provide engineering services for the 940-MW Koralm pumped-storage hydropower project in Austria.

The pair will provide a project review and feasibility study before preparing tendering documents, construction design and providing site supervision services.

The Koralm plant will include an upper and lower reservoir, headrace, penstock and tailrace, surge tank, cavern powerhouse and access tunnel, transmission line and switchyard. The plant is expected to have a head of about 650 meters and will the largest hydroelectric plant in Austria upon its completion.

HRW-Hydro Review magazine noted in a recent edition that pumped-storage hydropower is experiencing a surge in Austria given its increase in other forms of renewable generation, including wind and solar.
