Origis Energy and the Tennessee Valley Authority (TVA) announced that the Golden Triangle II solar and solar energy storage project in Mississippi is now complete. Model with a capacity of 150 MW_AC The 50 MW solar and battery storage project began producing emission-free electricity on May 21, 2024.

“Solar energy enhances Mississippi’s economic competitiveness, and Origis is removing barriers to a cleaner and brighter future by building clean energy infrastructure in the region,” said Johan Vanhee, Origis chief commercial and procurement officer. “Golden Triangle II is the first step in supporting a statewide zero-carbon economy that supports our nation’s economic goals and energy security.”

Two other Origis renewable energy projects are underway in the Magnolia State – Golden Triangle I in Lowndes County, a 200-MW plant_AC 50 MW battery project and Optimist in Clay County, a 200 MW project_ACproject including a 50 MW battery storage facility. This is the largest battery portfolio under construction in the state. When completed in 2025, Mississippi’s Origis Clean Energy Complex will have a total capacity of 550 MW plus 150 MW of battery storage.

“As a national leader in clean energy, TVA is at the forefront of reducing carbon emissions across all sectors of the economy and providing the clean energy needed to fuel our region’s growth,” said Amy Tate, TVA’s Southeast region general manager. “Together with partners like Origis, TVA is developing carbon-free energy solutions that create jobs and investments in the communities we serve.”

Origis Energy has developed, constructed and will operate three projects for TVA. Each location will provide clean energy at competitive prices through power purchase agreements (PPAs) between TVA and Origis. TVA will use this power to help meet the energy needs and sustainability goals of some of its large industrial customers through the Green Invest program, including Meta. Golden Triangle II will support Meta’s operations in the TVA area as part of a project with a capacity of over 1,000 MW_ACcapacity Meta has started cooperation with TVA on.

“Collaborating with TVA through the Green Invest program has made it possible to support our operations in the Tennessee Valley with new solar power built in the region,” said Urvi Parekh, director of renewable energy at Meta. “This solar farm is Meta’s first renewable energy project in Mississippi, and we are excited to see it come online.”

RES provides construction services to Origis across the portfolio, employing an estimated 500 people across the three projects. Once the plant is completed, Origis Energy Services will operate and maintain the plant portfolio with approximately 9 on-site employees throughout the project’s more than 35-year lifespan. Industrial-scale battery storage for each location is provided by Prevalon Energy, a rebrand of battery energy storage company Mitsubishi Power Americas.

“RES is proud to be part of the team supporting Origis and TVA on Golden Triangle II and the rest of the portfolio to provide TVA customers with reliable, clean energy,” said AJ Jain, chief operating officer at RES. “In addition to local contractors, our nearly 500-person team has logged over one million hours without a job loss. Congratulations to the entire team!”
