The project involved full disassembly of HA1, transport of parts to the UCMH Reșița factory for inspection and repair, and reassembly and rotor-turbine testing on site.
The works were contracted to SSH Hidroserv, which subcontracted execution to UCMH Reșița. The 9,500 mm turbine rotor underwent complex machining using unique, large-scale equipment available only at UCMH.
This is a first for Hidroelectrica: a complex project delivered entirely in-house by Hidroelectrica, SSH Hidroserv, and UCMH Reșița.
Porțile de Fier I, on the Danube between Romania and Serbia, is one of Europe's largest hydro plants and supplies around 40% of Hidroelectrica's output.
