Realizing the Power of Data Marts

This paper presents a water and power utility taps nonoperational data with a power system data mart project. Power utilities have enjoyed predictable success at boosting system efficiency, reducing outages, and managing assets more effectively by investing in substation automation projects. But few utilities seem to realize they are short-changing their investment returns by failing to fully tap into the wealth of information collected by these automated components and delivering it to decision makers throughout the organization. The ubiquity of this information gap is as unfortunate as it is unnecessary. Every utility that has implemented microprocessor-based devices and supervisory control and data acquisition (SCADA) technology has the ability to a mass an incredibly detailed historical record of operational and nonoperational data relating to the performance of its generation
