Temporary power is the first design constraint

Most festival grounds run on generators and distributed power that’s carefully budgeted across sound, lighting, vendor stalls, and every bar on site. Equipment that draws more than its allotted circuit can handle doesn’t just underperform, it can trip a line that other vendors depend on. Anything brought in has to be sized to a known, fixed power draw that the festival’s electrical plan can account for in advance, not figured out on site.

Weatherproofing isn’t optional, it’s the baseline

A stadium concession stand is under a roof. A festival bar usually isn’t, or is under a tent that doesn’t fully block wind-driven rain. Equipment that would be fine in a climate-controlled venue needs a real weather rating for outdoor festival use, and dust, humidity, and temperature swings across a multi-day event all take a toll that indoor equipment was never designed to handle.

The wave problem: everyone arrives at once

Festival crowds don’t spread out evenly, they move in waves tied to set times, gates opening, and the walk between stages. A bar near a stage can go from empty to a hundred-deep line in the ten minutes after a set ends. This is a more extreme version of the concession-line rush at a theater or stadium, but compressed into a shorter, less predictable window, and often without the staffing flexibility a fixed venue has to call in more bartenders on short notice.

Cashless and RFID change what “fast” actually means

Most major festivals have moved to RFID wristbands or cashless payment specifically because cash handling slows a line down more than almost anything else. Once payment friction is mostly solved, the pour itself becomes the next bottleneck, and that’s usually where an automated station earns its keep, keeping the physical drink-making step in sync with a payment system that’s already fast.
