The Tennessee Valley Authority has issued a request for proposals for 200MW of renewable energy that would need to be online by the end of 2022.
Developers have until 15 May to submit proposals, including energy storage projects, TVA said.
The authority said a similar call in 2017 for 200MW resulted in the development of almost 675MW of solar power to supply Facebook and Google data centres.
TVA said it expects to triple its solar portfolio by 2021 as utility-scale solar installations become an increasingly economical option.
“This growth also aligns to increased demand from large business and industrial customers looking to locate operations in the Tennessee Valley, where they can access new green and clean power to help meet corporate sustainability goals,” TVA said.
