Xcel Energy SmartGridCity power grid uses OSIsoft PI system

San Leandro, Calif., September 22, 2009 —Xcel Energy successfully launched operations using OSIsoft’s PI System in Boulder, Colo. as part of the infrastructure for collection and management of time series data required to monitor and implement the SmartGridCity concept.

The PI System stores, in a single database, electricity usage meter data for households, substation performance and status data for all four Boulder substations.

The smart grid requires the electrical transmission and distribution industry to combine data from multiple sources in order to make dynamic grid management decisions. Traditionally, the operating data needed for a consolidated view of the grid and decisions made around that view get stored in separate systems and isolated to different business units.

When this happens, engineers have to spend hours and days trying to access this data and make use of all these resources. Use of the PI System allowed Xcel Energy to consolidate multiple data sources, including advanced metering infrastructure and substation data, into a single system. Also, meter data — which is traditionally used only for billing — now adds to the knowledge of operating conditions.

The PI System installed in SmartGridCity provides this information to multiple users when and where they need.

Founded in 1980, OSIsoft, Inc. is headquartered in San Leandro, Calif., with operations worldwide and is privately held.
