There are industrial machines that do just this. They move 100% of their lifetime in a specific spot so they're always tethered. Also farms are the premium spot for electrification. Tractors need to run for long times (especially in the HUGE farms in the US that are bigger than some countries...), but there are other vehicles that can be electrified like ATVs, forklifts and other small tools. The best thing is that many farms can produce their own electricity from biogas on-site. Or use the biogas directly in CBG converted engines.
