Arevon Energy has commenced the construction of its Kelso solar project in Scott County in the US state of Missouri in a significant step forward for renewable energy in the region.

The project, with a combined capacity of 430 megawatts defined conditions, is expected to bolster local economies and support Meta’s regional operations through long-term environmental attributes purchase agreements.

In March 2024, Arevon and Meta entered two long-term environmental attributes purchase agreements for the Kelso solar project.

Kelso, which is Arevon Energy’s first utility-scale renewable venture in Missouri, is now underway with the ground-breaking of its two phases, Kelso 1 & 2, in Scott County.

The first phase is set for completion by the end of 2025, with the second to follow in early 2026.

Arevon chief executive officer Kevin Smith stated: “Kelso Solar marks Arevon’s entrance into Missouri and when operational, will boost the state’s installed solar capacity by almost 50%. This major project furthers Arevon’s growing presence in the Midwest region of the US, which is a priority market for our company’s development activities.

“Celebrating the project’s construction alongside our partners and stakeholders also gives us the opportunity to recognise the immense economic benefits the project provides. I am grateful to Scott County for its partnership as well as its leadership in expanding homegrown and cost-effective energy in the state.”

The project’s development has already spurred economic growth in the area, with over 450 local workers expected to be employed at the peak of construction.

Primoris Services Corporation’s Renewable Energy business is tasked with the engineering, procurement and construction of both phases.

Over its operational lifespan, Kelso is projected to contribute more than $34m to local government, supporting schools, infrastructure and emergency services.

Arevon Energy achieved financial close for the project in March 2025, securing $509m in funding, comprising a $245m bridge loan, a $172m construction loan and $92m in credit assistance, with the Canadian Imperial Bank of Commerce serving as the administrative agent, left lead arranger and bookrunner.
