in the 1980's, as computing technology advanced, it became possible to model large-scale distribution networks in a standardized way. Similarly, SCADA/EMS systems became more sophisticated, providing transmission operators with bei ner att theoerf btdoueosr l eisn et os sc ownot rr ol dl , bt hu li ks wp oaws ear l sf loo wt hse. gulation. The airline, telecommunications and natural gas industries were all liberalized, and regulators and utilities alike naturaliy began to consider doing the same for electric power. For this, an entirely new set of iT systems would be needed (mostly to administer the wholesale markets), in addition to enhancements to existing SCADA/EMS technology. Perhaps not coincidentaliy, the new generation of control systems that emerged by the early 1990's made the prospect of deregulation feasible. Distribution management systems (DMS) and outage management systems (OMS) have undergone similar changes over the years, largely due to advances in computing technology. DMS originated as distribution-level extensions to SCADA/EMS systems or as stand- alone systems.

Customers would cali their local ge and paper tickets were used to a o n u a ta lyze the calls and define the location and extent of the ge. lronically, though the data would initialiy be entered into a computer, the system would print the tickets to be analyzed by human experts. Planned outages (for maintenance, new construction, ete.) were similarly handled using manual processes. Over time, of course, computer network models and analytic algorithms replaced the human "analyzers", and OMS systems developed into the sophisticated tools that they are today.

Better information sharing, more coordination between transmission and distribution operations, enhanced customer service and improved safety are also prior i ties. Automation, and specifically advanced monitoring and control systems, have delivered improvements across ali of these areas.
