February 2012 - Phoenix Sky Harbor International Airport and SunPower Corporation dedicated a 5.4-megawatt (MW) solar installation located atop the airport's facilities. SunPower designed and built the solar installation, and will operate and maintain the solar system through a solar services agreement with the airport. The system is expected to generate about 51 percent of the electricity demand at the airport's rental car center, two East Economy parking garages and toll plaza.

The solar project was facilitated in part by Arizona Public Service Company's (APS) Renewable Energy Incentive Program, which offers incentives to customers that help offset the costs of installing solar power. The renewable energy certificates (RECs) produced by the airport's solar system will be used by APS to help meet the utility's renewable energy standard obligation.

September 2010 - Arizona Public Service Co (APS) announced it is developing a 15-megawatt photovoltaic (PV) power plant at Luke Air Force Base in Glendale, Arizona. SunPower Corp. will design and construct the power plant on 100-acres of underutilized land at the base and APS will own and operate upon completion in summer 2011. The plant will use single-axis tracking to increase efficiency and is expected to generate the equivalent of 50 percent of the base's power demand.

This is the second solar project collaboration between APS and Luke Air Force Base. In 2006, APS provided $1.5 million in incentives to reduce the cost of integrating a 375-kilowatt solar system into the base exchange's (BX) new roof.

October 2009 - APS, an electricity utility serving about 1.1 million customers in Arizona, announced it has lowered the price premium for its voluntary renewable energy offering, APS Green Choice Rates, from 1.0¢/kilowatt-hour (kWh) to 0.4¢/kWh. Under the program, customers can purchase Green-e certified renewable energy from wind and geothermal resources in specific increments or as a percentage of their monthly electricity use. Customers also have the option of purchasing solar energy equivalent to half or all of their monthly electricity needs for 16.6¢/kWh.

The 60 percent drop in Green Choice Rates reflects the reduced difference in cost between conventional generation (mostly natural gas) and renewable generation last year when program supplies were purchased. APS expects to have enough renewable energy to meet the needs of residential customers, but may not have sufficient supplies to meet non-residential customer demand. The utility is encouraging nonresidential customers that want to participate to sign up by October 30, 2009.

February 2009 - The National Basketball Association (NBA) announced that it purchased 1.5 million kWh of renewable energy certificates (RECs) for 100% of the expected electricity needs of the NBA All-Star Game and festivities held in February at the US Airways Center and Phoenix Convention Center in Arizona. The NBA worked with Arizona Public Service to purchase the RECs and a portion of the funds will be used to support the development of a new green energy project. The US Airways Center, the home of the Phoenix Suns, is also planning to install solar panels on the center’s parking garage in July.

August 2007 - Arizona Public Service (APS) has unveiled a new green power program that offers customers the option to have either fixed blocks or percentages of their monthly electricity use supplied from renewable energy sources at a rate premium of 1¢/kWh. The Green Choice program will be supplied primarily from wind power purchases from New Mexico and geothermal power purchases from California. Customers must subscribe for a minimum period of one year.

November 2002 - In October, Arizona Public Service (APS) dedicated a 450-kW solar electric generating facility at the Prescott Airport about 100 miles north of Phoenix. The project is financed in part by APS and the 3,000 participants in the utility's Solar Partners program, who pay $2.64 more per month to purchase 15-kWh blocks of solar power.

APS plans to expand the new facility to as much as 5 MW over the next three to five years. In addition to the Prescott project, APS has constructed solar facilities in Flagstaff, Tempe, Scottsdale, Gilbert, Yuma, Glendale and at Prescott's Embry-Riddle Aeronautical University. APS plans to have a total of 3 MW of solar capacity installed systemwide by the end of 2003.

April 2001 - Arizona Public Service (APS) dedicated three new solar facilities that will serve customers of the APS Solar Partners program. The three projects: a 100-kW, high-concentration system in Glendale, a 175-kW system in Prescott, and a 125-kW tracking system in Gilbert, bring the amount of solar energy produced by the utility to nearly one megawatt.

APS Solar Partners participants pay $2.64 per month to have 15 kWh of their electricity needs generated by solar power. To date, there are nearly 2,500 registered program participants.

April 2000 - Arizona Public Service (APS) plans to add 388 kilowatts (kW) of new photovoltaics (PV) capacity to the more than 500 kW already installed at sites around its service territory. The new projects are planned for Yuma, Prescott, and other areas outside of Phoenix.

The PV additions will be funded, in part, through the utility's Solar Partners program. The most recent projects completed under the program are a 172-kW solar facility at the Glendale Airport and a 2-kW rooftop system on the San Luis City Hall. APS and the U.S. Department of Energy also provide funding for the program.

Earlier this year, APS switched the pricing of the program from a capacity-based charge to an energy-based rate. Participants now pay $2.64 a month for each 15 kilowatt-hour block of solar energy purchased (or 17.6¢/kWh) rather than $3.00 a month for 100 watts of PV capacity. According to the utility, the change represents a savings for most participants and allows customers to more easily calculate the amount of solar energy they receive.

October 1999 - Arizona Public Service (APS) completed its third installation under the company's Solar Partners program, a 34-kW photovoltaic (PV) system located at a covered parking facility in Scottsdale, AZ. The system is financed in part by APS customers who, as APS Solar Partners, pay $2.64 per month to have 15 kWh of their electricity needs met by solar power. The U.S. Department of Energy also provided funds through the Utility PhotoVoltaic Group (UPVG). The City of Scottsdale provided the site for the project.

September 1998 - Peter Johnston of Arizona Public Service reports that the utility is exploring the construction of several new solar plants in response to continued high levels of customer and community interest in the APS Solar Partners program. To date, two plants have been built, in Flagstaff and Tempe, and APS has committed to three additional plants in Flagstaff, Glendale and Scottsdale. Future plans include facilities in Yuma and Prescott Valley. The new projects will involve a greater degree of partnership with the host cities. Johnston made his comments at IBC's 2nd Annual Marketing Green Power Conference on September 18.

April 1998 - On April 17, Arizona Public Service (APS) began operations of a new 82-kW solar power plant built in Tempe to supply the utility's Solar Partners program. Program participants agree to purchase 100-watt blocks of power for $3 per month. To date, more than 600 Valley residents have signed up for the service, prompting APS to pursue plans for constructing more solar power plants in the Valley. APS operates a similar project in Flagstaff.

November 1997 - On October 10, Arizona Public Service declared operational an 82-kilowatt solar plant in Flagstaff, AZ, the first commercial plant in the state to be funded by customer contributions.

September 1997 - Due to an overwhelming response to the recently announced Solar Partners pilot program, Arizona Public Service (APS) has announced that it will expand its program statewide this fall. The response to the pilot well exceeded the utility's initial target. By June, 368 customers had purchased 728 units of 100 watts each, prompting APS to expand the size of the first solar generating plant 41 kW to 81 kW, as well as to announce plans for a second project.

June 1997 - Arizona Public Service (APS) has chosen Flagstaff as the first community eligible to receive power from a PV power plant to be built under its Solar Partners program. Residential customers will be given an option of signing up for 100-W blocks of solar capacity at a cost of approximately $3/month/block. The facility, scheduled for completion in late summer 1997, is expected to generate about 41 kW of capacity. Solar Partners will receive a commemorative pin and certificate marking their involvement in the program. APS has a similar program proposal for industrial and commercial customers under review by the Arizona Corporation Commission.

March 1997 - The Arizona Public Service (APS) Solar Partners program tariff became effective December 1, 1996. The company will develop up to 400 kW of "centralized photovoltaic systems" to supply solar electricity to customers who choose to participate in the Solar Partners program. The power will be sold in 100-W blocks of solar capacity. The effective solar electricity cost will range from 18 to 24¢/kWh, depending on customer class and season of the year. A portion of program costs will be shared with the Utility PhotoVoltaic Group (UPVG). APS will start marketing the program in late April 1997. The program is open to all APS customers.
