Aluminium smelters, which are supplied by captive power plants, can maintain their production even when disconnected from the external grid, a.k.a. islanded operation, provided that the captive plant can control frequency and voltage in a stable manner. Do you want to know more about this – please read the paper Ensuring Availability of Aluminium Smelters Through Island Operation Capability which Solvina presented at the IBAAS conference in September 2018,  or contact us for more information.
