Always check the venue's connection capacity: how many amperes are available and across how many circuits? Heavy users such as LED screens, coffee machines and kitchens consume more than expected. At outdoor events or temporary venues a generator is almost always needed.
Plan this generously: power is the backbone of your technical infrastructure. If it fails, everything fails. Always ensure redundancy and a technical point of contact who knows the venue. Live Impact checks the power supply as standard during the venue search.
