APS Recognized Among Top 10 in North America for Energy Innovation

–Arizona Public Service Company has been recognized as one of the top 10 electric utilities in North America for energy innovation according to GreenTech Media and GTM Research, a leading source for clean energy news, analysis and trade events.

“The award – titled “The Networked Grid: Top Ten Utility Smart Grid Deployments in North America” – was based on nominations from utilities and vendors and judged by GTM Research analysts.

“Technology is changing everything, including the electricity grid. Our challenge is to make sure APS is investing in technologies that provide value for our customers, make financial sense and are here for the long run. This award is an indication that we are on the right track,” said APS Director of Energy Innovation Barbara Lockwood.

Among its energy innovation projects, APS recently announced the testing of an energy storage system in Flagstaff, Arizona. The system is the size of a shipping container and can generate the equivalent power output of 1,200 hybrid cars. APS is testing several uses in an electrical distribution substation, where it may one day help to dispatch power temporarily during outages. Eventually, the system will support a solar power plant and help to get more renewable energy generation onto the grid.

Flagstaff is home to a number of APS energy innovation pilots including the Community Power Project, which is testing the effects of a high concentration of solar energy in a single distribution area. The study will enable APS to optimize the grid for a future where large percentages of customers in a neighborhood could have solar panels.

APS also is engaged in a self-healing/self-isolating grid pilot and a distribution fault anticipation pilot in Flagstaff. The latter two technologies help predict and manage system faults, resulting in reduced power outages and quicker repair times.

Later this year, a home energy information pilot will test customer benefits of in-home energy displays, programmable thermostats and residential demand response programs.

Earlier this year, APS energy innovation programs were ranked fourth nationally by Intelligent Utility magazine and IDC Energy Insights.

APS, Arizona’s largest and longest-serving electricity utility, serves more than 1.1 million customers in 11 of the state’s 15 counties. With headquarters in Phoenix, APS is the principal subsidiary of Pinnacle West Capital Corp. (NYSE: PNW).

APS Prepared to Meet Summer Demand

Company Provides Annual Update to ACC

APS is well positioned to meet the energy needs of its customers this summer, company officials told the Arizona Corporation Commission (ACC) today.

This message was part of APS’s annual summer preparedness briefing to the ACC. The presentation included this summer’s peak demand forecast, an inventory of available resources to serve that demand, a summary of APS’s system improvements, and the steps the company has taken to prepare for wildfires and other emergencies.

“One of our most important jobs each year is to make sure the APS system is ready when the summer heat arrives,” said Daniel Froetscher, APS Vice President of Energy Delivery. “We invest in the electricity grid, secure an ample supply of power for even the hottest days, and prepare in advance for storms, wildfires and other events that can cause power outages. When outages do occur, our top priority is to get the lights back on quickly and safely, while communicating regularly with our customers about our efforts to restore the power.”

In preparation for meeting the needs of its customers this summer, APS in 2011 invested about $250 million in system improvements. This included more than 40 miles of new and rebuilt power lines and the construction of seven new substations throughout the company’s service territory.

This summer, APS anticipates a peak of 7,067 megawatts (MW), compared with the 2011 summer peak of 7,087 MW, which occurred on Aug. 24, during the hottest monsoon season ever recorded in the Valley. Between its existing generation, and long- and short-term contracts, APS has 8,696 MW of resources available to help meet summer demand.

The all-time APS system peak of 7,236 MW was set on July 21, 2006. (The summer peak – the 15-minute period when APS customers require the most energy – typically occurs in July or August between 5 and 6 p.m.)

APS successfully met peak demand in 2011 while providing its 1.1 million customers with record high levels of reliability. For the year, the typical APS customer experienced 0.79 power outages compared to a national industry median of 1.12 interruptions. Meanwhile, the typical APS customer experienced 69 minutes of interrupted service in 2011, compared with an industry median of 114 minutes. Both marks are APS records and fall within or near the top quartile of the industry.

In the event of large-scale customer outages, the company utilizes its Twitter outage feed, @APSOutageCenter, to provide real-time updates to its customers and other key audiences.

The state’s other major electric utilities also made presentations to the ACC.
