Driving the sustainability shift

As Louisiana transitions to clean energy, the Bayou Chicot Solar Project is a flagship initiative supporting the state’s broader climate goals. Designed to power tens of thousands of homes, the project reduces reliance on fossil fuels and fosters a sustainable future. Yet the path forward required careful navigation of environmental challenges, including wetland preservation and wildlife protection. Bisected by wetlands and streams, the site presented complex permitting and design hurdles. With support from Onterris, the project team minimized ecological impact, ensuring long-term sustainability.


Collaboration for clean energy

Onterris worked alongside ibV Energy Partners, a U.S.-based renewable energy firm, to secure permits, conduct environmental assessments and ensure regulatory compliance. With a multi-million-dollar investment, the project strengthened energy reliability and supported job creation across the region. A key environmental milestone was the wetland delineation process. Of the site’s 1,817 acres, 433 were assessed for potential wetland impact. Through thoughtful design and a commitment to responsible land use, disturbance was limited to less than half an acre, below regulatory individual permitting thresholds.

Our commitment to environmental stewardship extended beyond wetlands preservation alone. Onterris evaluated and protected habitats for threatened and endangered species, including monarch butterflies and bald eagles. The result: a solar farm that delivers clean power with minimal ecological disruption.

Field data only matters if it is utilized. The team kept permitting, delineation and design moving together so the project could stay buildable while protecting sensitive terrain.

Community engagement and impact

The Bayou Chicot Solar Project is more than a renewable energy installation; it is a valued community asset. Once operational, it will generate enough electricity to power approximately 30,000 to 40,000 homes. During construction, it will create jobs and stimulate the local economy.

Field teams endured extreme conditions, including temperatures reaching 120°F, to complete surveys and assessments safely and effectively. Their resilience and collaboration ensured the project stayed on track despite the heat.

Community involvement was essential throughout development. Coordination with local officials, including those in Evangeline Parish, reflects a shared commitment to sustainable energy and responsible land stewardship. This project demonstrates how large-scale clean energy initiatives can deliver long-term benefits to both people and the planet.


A replicable model for large-scale renewables in sensitive terrain

More than a solar project, Bayou Chicot is a model for how public-private collaboration, state-based climate change goals and environmental integrity can drive progress. As it advances, this initiative will inspire future renewable energy efforts across Louisiana and beyond, anchoring them in lessons of resilience, reliability and respect for the community they serve.
