Meta on Dec. 11 announced that its Mesa, Ariz., data center will soon be supported by new solar energy from Salt River Project through a contract with Orsted.
Under the contract, Meta (formerly know as Facebook) will receive the majority portion of the solar energy generated by Orsted’s Eleven Mile Solar Center, a 300-MW solar farm and 300-MW, four-hour battery energy storage system currently under construction in Pinal County, Arizona.
Once online in 2024, this will be the largest solar-plus-battery project on SRP’s power grid, and one of the largest battery energy storage systems built in a single phase in the U.S. The solar and stored energy not needed by the Meta data center will be available to SRP’s larger customer base.
In addition to this newly announced project, Meta will also receive an allocation of 50 MW from the 100-MW West Line Solar Facility, which opened earlier this year in Eloy, AZ, and will soon receive a portion of solar energy from the 200-MW Brittlebush Solar Facility in Coolidge, AZ, which is expected to be online in 2024. These projects will each further enable Meta to reach its 100% renewable energy and net zero goals, SRP noted.
“As SRP focuses on responsibly decarbonizing our generation mix, we will need to more than double our power resource capacity by 2035. Strategic partnerships with customers like Meta and renewable energy developers like Ørsted help us get there,” said Bobby Olsen, Chief Planning, Strategy and Sustainability Executive at SRP.
Eleven Mile Solar Center is expected to be operational in 2024. Located on over 2,000 acres, the solar and battery energy storage system is estimated to generate $89 million in tax revenue over its lifetime, which will benefit the local school districts, the cities of Coolidge and Eloy, and Pinal County.
The project’s storage capacity will contribute to the more than 1,100 MW of large-scale batteries that will be online on SRP’s system by the end of 2024.
This announcement follows SRP’s recent Integrated System Plan adoption, which incorporated community and customer perspectives "to develop a reliable, affordable and sustainable plan to meet an expected growth in energy demand by 2035," SRP noted.
SRP’s Integrated System Plan will pursue battery investments, new solar additions and more, backed by modern generation resources like flexible natural gas to ensure continued delivery of affordable and reliable power that SRP customers expect, it said.
SRP’s plan prepares to add 7,000 MW of new renewable resources, which includes 6,000 MW of new, large-scale solar resources by 2035. This will triple SRP’s current extensive portfolio of solar resources scheduled to come online by the end of 2025.
