Stadiums and other event venues are complex facilities, featuring multiple systems that all must work in tandem during concerts, sporting events, conventions, and any other large scale public gathering. A stadium needs lighting systems, security, point-of-sale, ticket collection, video displays, and many other systems in order to create the right environment for fans, players, performers and personnel. A power surge that damages electronic systems can be catastrophic for the stadium, causing interruptions, downtime and destruction of equipment.
Should one of these systems go down, it creates issues beyond the loss of the system functionality. A point-of-sale system not functioning during an event means that sales cannot go through, resulting in massive losses in revenue from concessions and merchandise. Should ticket collection mechanisms not properly function, tickets could be counted inaccurately, resulting in unauthorized persons sneaking into an event or authorized persons not being granted access.
