There is one "Area" with many plugs, with probably an 8' table. I haven't gotten the latest on the power situation, but in past discussions getting an industrial generator and hiring an electrician for the setup and maintenance has been tossed around, as has improved local cell service, but no idea what will/will not be implemented.
As far as how, it's pretty much an "AC power provided here" setup. you bring your charger, find an empty plug charge, then you take your charger. Last year we had HEAUGE issues with people abandoning their charger for the day, leaving it plugged in (sometimes with a battery, sometimes not) consuming both table and outlet space and tripping breakers (just because it's not charging the battery doesn't mean the power supply isn't drawing considerable power). fortunately the breaker made for a regular "time to clean up" notice. Whenever it tripped, everyone in the tent who was charging got called over and if you weren't in earshot of the tent, you got unplugged.
This year we hope to NOT repeat the breaker games, and have better posted rules (One more thing I'm going to try to slip this into the "festival etiquette" PSA), but not positive how we're going to manage/police the charging area.
USE YOU OWN.
(I'm not mad, just emphasizing -- FT will only be providing power, and unless you know the person REALY WELL, don't use their charger.)
