APS doubles its solar generation capacity

Dedicates solar plants in three Arizona communities

PHOENIX, Az., April 10, 2001 — APS doubled its solar generating capacity last week with the dedication of three new solar facilities, bringing the amount of solar energy produced by the utility to nearly one megawatt. One megawatt is enough energy to power 1,000 homes.

As part of the APS Solar Partners Program, three new power plants were dedicated in the Arizona communities of Glendale, Gilbert and Prescott at Embry-Riddle Aeronautical University.

“We are pleased to reach the one-megawatt milestone with the dedication of these three plants, but it’s only the beginning,” said Ed Fox, APS Vice President, Communications, Environment and Safety. “With the need for additional electric supplies in the West, every kilowatt of power generated helps meet customer needs. More importantly, these plants showcase APS’ commitment to developing earth-friendly, renewable energy resources.”

The three new solar plants feed energy directly to the electric grid.

* In Glendale, the City’s municipal airport hosts Arizona’s first commercial application of high-concentration photovoltaic arrays, with the dedication of the plant’s second phase. This technology tracks the sun’s movement and uses special lenses to magnify the sun’s rays 250 times onto each solar cell. The recently completed second phase features 100 kilowatts (kW) of high-concentration arrays to complement the 72-kW flat-plate tracking photovoltaic power plant built last year.

* In Prescott, APS and Embry-Riddle Aeronautical University joined to construct a 175-kW plant.

* The last of the three facilities dedicated was a 125-kW plant in Gilbert. The one-acre site consists of 10 solar arrays, which track the sun from east to west on a single axis. Each solar array (or series of panels) is about 150 feet long and 8 feet wide and sits relatively low to the ground.

APS Solar Program

All APS solar power plants are financed in part by APS and participating customers who, as APS Solar Partners, pay $2.64 per month to have 15 kW hours of their electricity needs generated by solar power. To date, there are nearly 2,500 registered program participants.

APS Solar Partners funds help support the additional costs of building, operating and maintaining the new APS solar power facilities. The rest of the costs are covered by APS and the U.S. Department of Energy through the Utility Photovoltaic Group (UPVG).

Other APS Solar Partner power plants are located in the Arizona communities of Flagstaff, Scottsdale and Yuma. APS plans to have two megawatts of solar capacity installed by the end of 2001. Program registration is available online at www.aps.com or by calling 1-800-659-8148.

APS, Arizona’s largest and longest-serving electric utility, serves more than 857,000 customers in 11 of the state’s 15 counties. With headquarters in Phoenix, APS is the largest subsidiary of Pinnacle West Capital Corporation.
