Arizona Public Service (APS) is a subsidiary of Pinnacle West Capital and distributes power to 1.2 million customers in 11 of 15 Arizona counties, making it the largest electric utility in the state. It operates 5,900 miles of transmission lines and more than 29,100 miles of distribution lines; it generates more than 6,100 MW of capacity, mainly from fossil-fueled and nuclear power plants. APS also purchases power from other suppliers to supplement its company-owned generation capacity.
APS was facing a perfect storm of:
All these changes were requiring operators and field employees to spend inefficient amounts of time using many different software tools to manage the grid. And most importantly, operators did not always have an accurate depiction of the immediate state of the electric grid.
In 2014, APS decided to implement Schneider Electric’s advanced distribution management system (ADMS) suite to consolidate all the tools needed to perform distribution operations activities into one enterprise-wide system that enables operators to maintain awareness of the state of the grid in real-time and make informed decisions.
During the implementation process, APS faced a couple of significant challenges in preparing operators and field employees to utilize the new system and tools effectively:
To equip APS operators and field personnel with the knowledge and skills needed to utilize the new ADMS effectively at go-live, Mosaic rolled out a role-based, scenario-driven training approach that included the following components:
Mosaic’s deep expertise in control room operations, Schneider’s ADMS platform, and process-based training has helped APS increase the speed of system adoption both in the control room and in the field, and has improved the efficiency of transmission and distribution system operators.
