TVA grows solar portfolio by 44%, includes storage

In its latest quarterly financial call, the Tennessee Valley Authority (TVA) announced the addition of 484 MW of new contracted solar capacity since December, an increase of 44 percent. These five new projects resulted from TVA’s 2019 request for proposals for renewable energy projects and have been matched to customer requests for new renewable energy.

Issued in April 2019, the RFP called on the nation’s top developers to submit proposals to develop 200 megawatts of renewable energy that could be brought online by the end of 2022. A total of 3,700 MW of offers were received, and 484 MW were selected based on current demand.

 “We are moving to contract large volumes of solar for our customers, whether it’s for large business customers through the Green Invest program, or smaller businesses or residential customers who use our Renewable Energy Certificate programs to help offset their carbon footprint,” said Doug Perry, TVA vice president of Commercial Energy Solutions. “TVA is pleased to bring renewable options to the table to help reach their sustainability goals.”

In a first for the agency, 200 MW of solar has been contracted by TVA for its REC programs available to Valley consumers, both large and small. The project was awarded to Origis Energy to construct, own, and operate a solar installation in Lowndes County, Mississippi (Golden Triangle region).

The project also includes 200 MWh (or 50 MW for 4 hours) of battery energy storage, which will make the solar power generated by this installation more efficient and able to be used when it’s most valuable to the system. It’s a key component to enabling the growth of solar while ensuring reliability during peak demand, even when the sun isn’t shining.

Four additional projects have been contracted under TVA’s new Green Invest program on behalf of large business and industrial customers. The first Green Invest agreement between TVA, Nashville Electric Service, Vanderbilt University, and Silicon Ranch for 35 MW of new solar for the university was announced in January.

The details of the remaining Green Invest projects emerging from the 2019 RFP follow, with customer announcements pending through 2020.
