Salt River Project’s board of directors has approved an agreement to purchase the energy produced from Apple’s new 50-megawatt photovoltaic solar power plant in Pinal County east of its data command center in Mesa.

SRP was part of an Arizona team that worked with Apple to locate in the East Valley in 2014. It later built an interconnection near the facility to help facilitate the construction of the Bonnybrooke PV solar plant.

Apple has completed construction of the plant. It is finalizing the commissioning of the large-scale solar array so clean power can feed into SRP’s grid that supports Apple, according to a press release.

“SRP is committed to working with our customers like Apple to meet their energy needs with the accelerated development of renewable resources, such as solar and geothermal, without increasing costs to our other customers,” SRP General Manager and CEO Mark Bonsall said in the release.  “This opportunity is not only economical, but a powerful demonstration of how SRP can be a catalyst for economic development in the Valley.”

By purchasing the output of the Bonnybrooke plant, SRP will reduce the carbon footprint of the fossil fuel resources that serve its more than one million customers in the greater Phoenix metropolitan area, according to the release.

The terms of the 25-year purchase power agreement support new renewable energy and development in Arizona, but do not impact other SRP ratepayers as the energy is purchased by SRP at a wholesale market rate. Apple will retain all of the environmental attributes generated from the solar plant.
