With the recent completion of infrastructure build-out and software deployment, Xcel Energy says its SmartGridCity project in Boulder, Colo., has become the world's first fully operational smart grid-enabled city.

The utility explains that all the automated functions of SmartGridCity have been linked, including those related to switching power through fully automated substations; re-routing power around bottlenecked lines; detecting power outages; and identifying outage risks. The deployment integrated more than 20 applications, 95 new interfaces and more than 300 test cases, Xcel says.

The SmartGridCity project also includes automating three of four distribution substations, four computer-monitored power feeders and another 23 feeders that are watched for voltage irregularities. Approximately 200 miles of fiber optic cable, 4,600 residential and small business transformers and nearly 16,000 smart meters are now connected to the system.

In the fourth quarter of this year, Xcel plans to launch an in-home energy management Web portal that will give all Boulder customers with a smart meter the ability to review their in-home energy usage. This service will enable customers to design and personalize energy consumption strategies.

The project launch was a collaborative effort of Xcel's Smart Grid Consortium, which includes Accenture, CURRENT Group, GridPoint, OSIsoft, Schweitzer Engineering Laboratories, SmartSynch and Ventyx.
