The above is quoted from the atricle, which on the whole, seems factual and accurate. However, UPS systems are available, in single phase and larger three phase iterations, that will run anything from a small server to a small town, for as long as would be economical for any particular installation, but easily for a nuimber of hours. The 30 minute figure mentioned in the article refers to "standard" run times. Major manufacturers offer extended run time packages to suit most needs, and a few will put together a unit with as much run time as you could reasonably want. There is, of course, a point beyond which an emergency standby generator, used in conjunction with a standard run time UPS, makes more sense, but the key point is that UPS systems can be configured to provide hours, as well as minutes of service.
