ÖBB-Infrastruktur AG, the operator of the infrastructure of the state-owned Austrian rail network on behalf of the Austrian Federal Railways (Österreichische Bundesbahnen or ÖBB), invites bids by 6 October for the supply and installation of the 50 Hz internal supply via a new 20kV medium-voltage network to be built, as well as the electrical equipment for the entire Obervellach II powerplant.
The contract will entail: planning, construction and construction preparation; manufacture and factory assembly; delivery and assembly on site; and, commissioning and documentation.
The Obervellach II project involves the construction of a new 38 MW plant in the southern state of Carinthia to replace two existing run-of-river stations at Lassach and Obervellach, which have supplied energy to power the railways since the beginning of the last century and are at the end of their technical lives. The 16.7 Hz project, which will harness the waters of the Mallnitzbach, Dösenbach and Kaponigbach rivers and make use of pondage with a storage volume of 60 000 m3, is designed to generate 125 GWh/year from a flow of 9 m3/s under a gross head of 488 m.
