Project Summary:

Arizona Public Service (APS) is a utility company headquartered in Phoenix, Arizona. With a generation capacity of about 4000 MW, APS serves more than a million electricity consumers in the northern and central parts of Arizona [1].

In early 2010, Arizona Corporation Commission approved APS solar pilot project in Flagstaff. APS expected to install utility-owned solar arrays on approximately 200 homes, solar water heaters in about 50 homes, and small-scale, stand-alone wind turbines on approximately six properties in a limited distribution area in northeast Flagstaff [2]. The technologies employed in the APS smart grid project include, for example, intelligent diagnostics, automation technologies, and central distribution information management systems. These technologies allowed APS to measure and track the effects of weather, equipment failure, customer usage, and other types of operational impacts on the distribution system.

According to [3], Flagstaff Smart Grid Pilot was deployed in 95% of Flagstaff, and portions of Coconino County. As of May 2010, APS had:
- Installed 36,000 Automated Metering Infrastructure (AMI) meters by Aug 2009.
- Automated 15 distribution feeders out of 4 Flagstaff substations.
- Provided sensing technologies to detect power outages and fault indications.
- Adopted self-healing technologies on 4 feeders.
- Deployed large pipe fiber communications.
- Installed 1.5MW distributed solar energy and energy storage systems.

The company began its first phase of deployment in 2005 with more than 160,000 meters by contracting with PowerOne Data [1]. The company had partnered with KORE Telematics for the wireless communications services and Elster Integrated Solutions for the data collection services with new electric meters to achieve its AMI [5]. The Meter Data Management Software for APS’ AMI had been developed by Aclara [5].
This Community Power Project is located within the boundaries of APS’s Sandvig 4 electrical distribution feeder in the Doney Park and Timberline neighborhoods of northeast Flagstaff. APS expected to generate 600 kW from area homes, 400 kW from commercial installation, 500 kW from a small, utility-scale renewable energy generation site, including 8kW of wind energy and energy storage [6].
