Project Overview

Golden Triangle II is part of a portfolio of projects in Mississippi, including Golden Triangle II and Optimist, with a total capacity of 550 MW plus 150 MW of battery storage. This is the largest battery storage portfolio announced in Mississippi and the largest solar portfolio under construction in the state, maintaining TVA’s leadership in clean power generation.

The three projects were developed, are being constructed and will be operated by Origis Energy, one of America’s leading renewable energy platforms. Each will deliver clean energy at competitive rates under Power Purchase Agreements (PPAs) executed between TVA and Origis. TVA will then use the power to help meet the sustainability goals of some of its large industrial customers, along with residents in Mississippi.

“TVA is a clean energy leader, and we’re working with partners, like Origis, to add solar power to our system to meet customer demand,” said Jeremy Fisher, SVP Commercial Energy Solutions with TVA. “Projects like these, ensure we can continue to provide affordable, reliable, resilient and sustainable energy to fuel the region’s economic growth.”

01

Roughly 1.5 million solar panel modules will be installed at the three sites, enough to power an estimated 126,000 homes.

02

Following the pandemic, TVA’s low-cost, clean and reliable electricity, coupled with unprecedented migration into the area, resulted in a rebound in economic growth in the region of 8% in 2021 and 3.5% in 2022.

04

Upon completion of the plants, Origis Energy Services will operate and maintain the portfolio, employing approximately 9 on-site jobs over the 35+ project life years.

Estimated economic benefits from the three projects include $106 million in near-term construction and hiring gains to the area. Over the life of the solar plants, they will provide another $145 million in estimated regional economic benefits.

ECONOMIC IMPORTANCE

“Partnering with TVA on the Green Invest program has made it possible for our operations in the Tennessee Valley to be supported by new solar energy constructed in the region,” said Urvi Parekh, Head of Renewable Energy at Meta. “This solar farm is Meta’s first renewable energy project in Mississippi, and we’re excited to see it come online.”

“Origis Energy and TVA’s announcement of the commercial operation of Golden Triangle II represents a significant milestone in our commitment to advancing clean energy solutions,” stated Tom Cornell, President and CEO of Prevalon Energy. “We are honored to be part of this project, enabling more renewable generation in TVA’s service territory. By generating carbon-free electricity, this project not only supports Mississippi’s economic competitiveness but also contributes to a cleaner, brighter future for the region. We are excited to be part of this endeavor and look forward to continuing to support sustainable energy initiatives with Origis and TVA.”

ENERGY IMPORTANCE

Golden Triangle II will deliver clean energy and grid resiliency at competitive rates under Power Purchase Agreements executed between Origis Energy and TVA.
