The world's most powerful electrolysis process at the time of commissioning in 2013
Alstom Grid's turnkey solution draws on nearly 30 years of experience working together with Alcan - a proven track record that can be traced back to the first Pechiney potlines in Chicoutimi county, Quebec.
Alstom Grid completed its scope of work for the AIS/GIS substation and AC/DC conversion groups at the Jonquière site well in advance of its projected completion in 2013.
The full range of equipment, which included specially developed and patented technology for the new AP60 process, comprised: 161 kV air-insulated (AIS)/gas-insulated (GIS) substation, cables, AC/DC conversion groups, process loop compensation groups, Power Factor compensation and harmonic filter banks and associated Level 1 and Level 2 control systems for the HV power station and AC/DC conversion substations.
