Commencement of commercial operations of Origis Energy and TVA Golden Triangle II in America

Origis Energy and the Tennessee Valley Authority (TVA) announced that the first of three solar and storage projects in their portfolio in Mississippi have reached commercial stage. Golden Triangle II, a 150 MWac solar project with 50 MW batteries, 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, chief commercial officer and chief development officer at Origis. “Golden Triangle II is the first step in supporting a statewide zero-carbon economy that supports our nation’s economic goals and energy security.”

There are two other Origis renewable energy projects underway in the Magnolia State – Golden Triangle I in Lowndes County, a 200 MWac project with 50 MW energy storage, and the Optimist project in Clay County, a 200 MWac project with 50 MW energy storage. It is the largest battery portfolio under construction in the state and helps TVA maintain its leadership in clean energy generation.

When completed in 2025, Mississippi’s Origis Clean Energy Complex will have a total capacity of 550 MW plus 150 MW of battery storage. About 1.5 million solar panel modules will be installed across the three sites, enough to power about 126,000 homes.

“As a national leader in clean energy, TVA is leading the way in 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 director for the Southwest region. “Together with partners like Origis, TVA is developing carbon-free energy solutions that create jobs and investments in the communities we serve.”

Estimated economic benefits from the three projects include $106 million in short-term construction and employment gains in the area. They will provide another $145 million in estimated regional economic benefits over the life of the solar complex.

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.
