high-voltageswitchgear evacuation for Power Supply

I'm currently in the process of specifying the electrical system for an evacuation lift for a new site. I've only ever heard of using a generator, battery inverter or a separate supply from a different substation. However, in BS9999:2017 under section G.2.2 Power Supplies it gives the impression (to me at least) that you could potentially use a single incoming supply to provide both lift ...
