Following its recent announcement to expand utility-scale solar resources to 2,025 megawatts by 2025, Salt River Project has announced three new solar energy plants that will deliver a total of 500MW of renewable energy.  

Facebook announced it will be SRP’s largest off-taker of these new clean energy resources, utilizing 450MW of the combined solar capacity to support Facebook’s newly announced data center in Mesa, and help meet the company’s 100-percent renewable energy commitments. 

The three projects include two 200MW solar plants and one 100MW solar plant. SRP is contracting with subsidiaries of solar developers AESEDP and NextEra Energy Resources to construct and operate the three new plants. The first project is expected to come online in fall 2022 and start of construction for all the new solar plants, which will all be located in Pinal County, will begin at different points in time throughout 2022. 

The Facebook data center in Mesa will receive water credits for its operations from an agreement with Gila River Water Storage, LLC, SRP’s joint venture with the Gila River Indian Community, which provides renewable water in the form of Long Term Storage Credits to entities seeking additional supplies. The data center will procure these LTSCs from GRWS water storage, which means that it will not use any water rights from Mesa’s municipal supply for operations. 

Adding 500MW of renewable solar energy to SRP’s power grid to support the energy needs of Facebook’s data center in Mesa, as well as SRP small business customers, will save hundreds of millions of gallons of water per year than if the same amount of energy were generated by fossil fuel-burning resources. 

Below is further detail on the new solar energy plants: 

West Line Solar, Solar Developer: AES (100 MW) 

The first of the new solar plants scheduled to be commercially operational is “West Line Solar.” The 100MW plant will come online in October 2022 and SRP is partnering with The AES Corporation, a Fortune 500 global energy company, to develop this solar resource which will be located in Eloy.  

West Line Solar will be 650 acres in size and construction is set to begin in spring of 2022. Facebook will receive 50MW of solar energy from this solar plant, leaving 50MW of available renewable energy that SRP will offer to residential and small business customers as part of its new solar offerings available later this year. SRP and AES have worked together to bring online a 100MW solar system, East Line Solar, as well as a 10MW, 40MWh standalone battery-based energy storage system that helps inject power into the grid during times of high customer demand. 

Randolph Solar Park, Solar Developer: EDP Renewables North America (200 MW) 

The next new solar plant to become commercially operational will be “Randolph Solar Park,” which is slated to come online in 2023. SRP is partnering with EDP Renewables, a global leader in renewable energy production, to develop and operate this 200MW solar park located in Coolidge, adjacent to SRP’s Randolph 230kV substation. Randolph Solar will span across 1,346 acres, and construction is anticipated to begin in fall of 2022. Facebook will receive the full 200MW of energy from this solar plant. 

Valley Farms Solar, Solar Developer: NextEra (200 MW) 

The third project, “Valley Farms Solar” is expected to become commercially operational by December 2023. SRP has contracted with a subsidiary of NextEra Energy Resources, the world’s largest generator of renewable energy from the wind and the sun, to develop this 200MW solar plant located in Coolidge. The two companies have previously worked together to develop and contract a 20MW solar generation facility and battery storage system, Pinal Central Solar Energy Center, and a 100MW solar plant, Saint Solar, which began operations in 2018 and 2020 respectively. Additionally, SRP and NextEra have plans to develop two solar-charged battery projects totaling nearly 350MW, Sonoran Energy Center and Storey Energy Center. Valley Farms Solar will be 1,900 acres in size and construction will begin in winter of 2022. Facebook will receive the full 200 MW of solar energy from this solar plant. (Source)
