Implementing back-up control centers [for power systems]

Summary form only given, as follows. The original power system control center backup plan was to have redundant systems to avoid hardware problems. In today´s environment, it is necessary to have back-up systems that provide security and functionality that go well beyond the basic redundant system. In addition to regulatory pressure for back up control centers, there is also the internal need to improve security and reduce operating costs. This presentation describes what companies are doing to provide back-up control systems to address a multitude of requirements such as network and equipment security, multiple time zones, data integration, communication issues and system support.
