Arizona Utility to Deploy Advanced Control Systems Distribution Automation

Advanced Control Systems has contracted with Arizona’s Electrical Power District No. 3 of Pinal County (ED3) for the deployment of an ACS distribution management and automation system.

ED3 made its selection after a careful review of available solutions on the market. With project engineering and implementation support from ACS, ED3 is deploying an ACS PRISM system comprising dual redundant Linux servers and Linux-based operator terminals. ED3 will also deploy ACS Connex 60 substation managers as part of the integrated system solution.

ED3 chose the integrated ACS system to improve the security, quality and reliability of electrical power service to its rapidly growing customer base. In subsequent phases, ED3 plans to roll out additional solutions from ACS including advanced DMS applications and feeder automation.

“We selected ACS because of its smart grid vision for distribution applications and automation, its history of customer success and for its cost-effective approach that integrates our current and ongoing infrastructure investments,” said Joseph Herrera, director of engineering and operations for ED3.

Created in 1926 and headquartered in Maricopa, Arizona, Electrical District No. 3 of Pinal County supports a rapidly growing area of 133,000 acres 20 miles south of Phoenix, Arizona. Between 2000 and 2006 the district’s customer base grew from 500 irrigation and residential customers to more than 16,000 new residential and it continues to add over 300 new customers per month. ED3 operates nine substations that feed a growing 12.47 kV distribution system comprised of overhead lines and underground service connections.
