Direct answer
Battery-powered shades may continue local operation during a utility outage if their controls and radio system remain available. Hardwired shades stop when their power supply loses electricity unless that supply is backed up. An internet outage is different: shades with local keypads, remotes, schedules, or automation processors may continue normally, while remote app access and cloud-dependent voice control may stop.
Document the control path for the exact motor and system. Bedrooms, egress-sensitive areas, and very tall windows need a practical manual or local fallback. If backup power is desired, size it for the shade power supply and control components and define expected runtime rather than assuming the network UPS covers motors. Test restoration behavior so shades do not move unexpectedly after a power event.
